MK-CONFIGURE(7)

NAME
mk-configure - lightweight replacement for GNU autotools

DESCRIPTION
mk-configure is a collection of include files for bmake (portable version of NetBSD make) and a number of executables. It is intended to simplify crossplatform development and software building.

There are only a few top-level makefiles: mkc.init.mk, mkc.mk, mkc.configure.mk, mkc.minitest.mk. Everything else (mkc_imp.*.mk files) is included implicitely. Do not use mkc_imp.*.mk files directly! If you do, I cannot guarantee backward compatibility. mkc.configure.mk is included automatically by mkc.mk, but can be included explicitely. mkc.minitest.mk provides a trivial support for regression tests and should be included explicitely. Usually mk-c makefiles consist of variables assignments and inclusion of mkc.mk in the and. One can also use mkc.prog.mk, mkc.lib.mk, mkc.files.mk, mkc.subdir.mk and mkc.subprj.mk instead of mkc.mk. The latter activates mkc.lib.mk if variable LIB is set, mkc.prog.mk if variables PROG or PROGS are set, mkc.subprj.mk if variable SUBPRJ is set, mkc.subdir.mk if variable SUBDIR is set, and mkc.files.mk otherwise.

To get system-wide configuration parameters, mkc.init.mk loads "${MAKECONF}" file if it exists. Otherwise, it loads @sysconfdir@/mk-c.conf if it exists. If neither ${MAKECONF} nor @sysconfdir@/mk-c.conf exist, it tries to load @sysconfdir@/mk.conf file. If "${SRCTOP}/Makefile.common" file exists it is also included by all subprojects. Unless SRCTOP variable is set, "../Makefile.inc" is also included if exists. These files may define any of the variables described below. Compiler-specific defaults are also loaded from "~/.mk-c" or system directories. This compiler-specific defaults are determined at build time or with the help of mkc_compiler_settings utility.

Below in square brackets the default value for variables are specified. In triangle brackets -- typical way of use, where I means "Initialized by mk-configure", Iu means "Initialized by mk-configure but may be overriden by user", Im means "Initialized by mk-configure but may be set in Makefile", U means "Usually set by user", M means "May be set or changed in project's Makefile" and Mu means "May be set in project's Makefile but may be initialized or overriden by user".

  Targets
Mk-configure provides the following targets:

all build everything.

clean
    clean temporary files and directories with the help of ${CLEANFILES_CMD} and ${CLEANDIRS_CMD} commands.

cleandir
    remove all of the files removed by the target clean, as well as cache files created by mkc.configure.mk.

installdirs
    create target directories.

install
    install programs, libraries, files, include files, manual pages etc. to the target directories with the help of ${INSTALL} program.

uninstall
    remove installed files with the help of ${UNINSTALL} command.

configure
    check for MKC_ERR_MSG variable and fails if it set printing an error message

depend
    create .depend_${.CURDIR:T} file containing list of dependencies (see mkdep(1)).

filelist
    output a list of destination files of the project, one per line, e.g.
      /usr/local/bin/hello
      /usr/local/man/man1/hello.1

obj if MKOBJDIR is "yes", creates object directories (${.OBJDIR}) according to MAKEOBJDIR and MAKEOBJPREFIX variables. Current umask is used for this.

mkgen
    See mkc_imp.foreign_autotools.mk.

bin_tar, bin_targz, bin_tarbz2, bin_zip, bin_deb
    build software, install it to a temporary directory (using DESTDIR) and create .tar/.tar.gz/.tar.bz2/.zip/.deb archive containing all installed files. The target bin_deb expects debian control files in DEBIAN subdirectory, see examples/files for the sample.

NOTE: Commands associated with targets all, install, clean, cleandir, depend, test, installdirs, uninstall, configure and filelist in Makefile override the standard behaviour.

NOTE: All targets in this list have pre_*, do_* and post_* counterparts. See ALLTARGETS for details.

MKINSTALLDIRS
    If "yes", install target directories (target installdirs) before installing files (target install). <Iu> [yes]

MKOBJDIR
    If "yes", the target "obj" creates object directories, if "auto", object directories are created automatically. Otherwise object directories are not created. <Iu> [auto]

BMAKE_REQD
    Minimal required version of bmake. If it is older, mkcmake exits with error. <Im>

MKC_REQD
    Minimal required version of mk-configure. If required version is not found, mkcmake fails. This variable should be set before mkc.init.mk is included, directly or indirectly. <M>

MKC_VERSION
    Version of mk-configure. This variable is always set to non-empty value when mkc.*.mk include files are used, so you can use it to initialize mk-c variables in mk.conf. For example: @sysconfdir@/mk.conf:
       ...
       .ifdef MKC_VERSION
       COPTS?= -O2 -Werror
       SHRTOUT= yes
       .endif # MKC_VERSION <I>

PROJECTNAME
    The name of a project. By default it is set to ${PROG}, ${LIB} or ${.CURDIR:T}. For a top-level project using either mkc.subdir.mk or mkc.subprj.mk it makes sense to set this variable explicitely in project's Makefile. This variable is initialized before including mk.conf, so you can use it to change build options, e.g. during development process. @sysconfdir@/mk.conf:
       ...
       .ifdef MKC_VERSION
       ...
       .if ${PROJECTNAME} == "foo"
       SHRTOUT= yes
       PROG.gcc= /usr/bin/gcc
       CC_TYPE= gcc
       COPTS= -O0 -g
       .endif
       .endif # MKC_VERSION <Im>

CC_TYPE
    C compiler type. This variable is set by mk-configure and can be overriden by user. It can get the following values: Value Description ---------------------- gcc GNU C/C++ compiler pcc Portable C compiler icc Intel C/C++ compiler msc Microsoft C/C++ compiler hpc HP-UX C/C++ compiler sunpro SUNWspro C/C++ compiler ibmc IBM C/C++ compiler (Visual Age for C/C++?) bcc Borland C/C++ compiler watcom Watcom C/C++ compiler como COMO C/C++ compiler decc DEC C mipspro MIPSpro C compiler <Iu>

CC_VERSION
    C compiler version. <I>

CXX_TYPE
    C++ compiler type. This variable is set by mk-configure and can be overriden by user. It can get the same values as CC_TYPE variable. <Iu>

CXX_VERSION
    C++ compiler version. <I>

LD_TYPE
    Linker type. This variable is set by mk-configure and can be overriden by user. It can get the following values: Value Description ---------------------- aixld AIX linker darwinld Darwin linker (MacOS-X) gnuld GNU linker hpld HP-UX linker interixld Interix linker scold SCO linker sunld SunOS linker osf1ld OSF1 linker (Tru64) irixld IRIX linker <Iu>

SHRTOUT
    If not "no", output messages about compiling, linking and creating libraries are shortened and formatted. <Iu> [no]

CFLAGS.warns.<cctype>.<warn-level>, CXXFLAGS.warns.<cxxtype>.<warn-level>
    These variables are set by mk-configure and enable warning messages for C or C++ compilers according to their types (CC_TYPE and CXX_TYPE) and warning level (WARNS). <Iu>

CFLAGS.dflt.<cctype>, CXXFLAGS.dflt.<cxxtype>
    Additional flags passed to C or C++ compilers according to their types (CC_TYPE and CXX_TYPE). <Iu>

CFLAGS.pic, CXXFLAGS.pic
    Options for C and C++ compilers for generating position independent code. On some platforms it makes sense to override these variables (initialized by mk-configure) for better performance, for example, one may use -fpic instead of -fPIC with GNU C/C++ compilers. See SHLIB_MAJOR, MKPIE etc. variables for more information. <Iu>

CFLAGS.pie, CXXFLAGS.pie
    Options for C and C++ compilers for generating position independent executables. On some platforms it makes sense to override these variables (initialized by mk-configure) for better performance, for example, one may use -fpic instead of -fPIC with GNU C/C++ compilers. See MKPIE variable for more information. <Iu>

CFLAGS.ssp, CXXFLAGS.ssp
    Options for C and C++ compilers for generating stack protection code. See USE_SSP variable for more information. <Iu>

USE_SSP
    If "yes", enables stack protection code, which detects stack overflows and aborts the program. This enhances security but imposes some performance penalty. <U> [no]

SRCTOP
    Top-level project's directory which defaults to ${.CURDIR} if ${.MAKE.LEVEL} is 0. If set, "../Makefile.inc" is not included. Also, the following command
       mkcmake -C subproject target

       cd ${SRCTOP}; mkcmake target-subproject <Iu>

OBJTOP
    Top-level object directory which defaults to ${.OBJDIR} if ${.MAKE.LEVEL} is 0. <I>

DPLIBDIRS
    See LIBDEPS in section mk.subprj.mk.

DPLDADD
    See LIBDEPS in section mk.subprj.mk.

Libraries are ranlib'd when made. mkc.lib.mk includes mkc.files.mk and therefore supports all variables supported by it.

The order of options passed to the C and C++ compilers are the same as in mkc.prog.mk.

  mkc.subprj.mk
The include file mkc.subprj.mk handles subprojects (subdirectories) organized as a dependency graph. It provides all targets provided by mkc.prog.mk. Variable SUBPRJ contains a list of pairs depdir:dir which mean that subproject dir depends on depdir. mkcmake all command will build all subprojects listed in SUBPRJ in a correct order (starting with subprojects having no dependencies and so on). There is also a target which allows the command bmake <subdir> where <subdir> is any directory listed in the variable SUBPRJ. The following targets are also provided: <target>-<subdir> where <target> is either of the following: all, clean, cleandir, depend, installdirs, install, uninstall and filelist. Also provided are: targets nodeps-<target>-<subdir> and subdir-<target>-<subdir>. Difference between <target>-<subdir> and nodeps-<target>-<subdir> is that mkcmake <target>-<subdir> runs the specified <target> for <subdir> and all its dependencies while mkcmake nodeps-<target>-<subdir> -- only for <subdir>. A target subdir-<target>-<subdir> is a synonym for nodeps-<target>-<subdir> See examples/hello_dictd subdirectory for the sample of use.

mkc.subprj.mk provides the following variables:

SUBPRJ
    List of subprojects (subdirectories) and dependencies. If the subdirectory doesn't exist the subproject becomes "virtual" and may be used to group several subprojects into a new virtual one. <M>

LIBDEPS
    A list of library dependencies. Each token is a colon-separated pair. Its first component is a library subproject (dependency), the second one is the subproject for library or executable. The value of this variable is automatically added to SUBPRJ. Library dependencies listed in LIBDEPS automatically change CPPFLAGS0, LDFLAGS0 and LDADD0 of approptiate subprojects. <M> Suppose, we have <library:program> pair in LIBDEPS, also suppose that variable library is set to "library" subdirectory and variable program is set to "program" subdirectory. ${SRCDIR_library}/linkme.mk file is automatically included from ${SRCDIR_program}/Makefile if it exists. In this file DPLDADD [${library:T:S/^lib//}], DPLIBDIRS [${OBJDIR_${library:S,/,_,g}}] and DPINCDIRS [${SRCDIR_${library:S,/,_,g}} ${OBJDIR_${library:S,/,_,g}}], may be set to non-default values. These three variables then changes LDADD0, LDFLAGS0 and CPPFLAGS0 respectively in subproject "program". The dependency graph specified by variable LIBDEPS is available to all subproject via environment.

STATICLIBS
    A list of subprojects (basenames) with static libraries. If dependency is mentioned in this variable, the suffix _pic is automatically added for PIE-executables or shared libraries that depend on this library. This variable is automatically passed to subprojects via environment. <Mu> []

INTERNALLIBS
    A list of subprojects (basenames) with internal libraries. These libraries are static and not installed by target "install". <M> []

COMPATLIB
    Subproject's basename for compatibility library. If this variable is set, MKC_SOURCE_FUNCLIBS and FEATURES do not change SRCS for subprojects other than ${COMPATLIB}. <M> []

SUBPRJ_DFLT
    List of projects built and installed by default. The default is all projects listed in SUBPRJ. <IMu>

EXPORT_VARNAMES
    List of variables to export before running make for subdirectories. <Mu> [MKC_CACHEDIRSRCTOPOBJTOPSTATICLIBSCOMPATLIB]

NOEXPORT_VARNAMES
    List of variables excluded from EXPORT_VARNAMES. <Mu> []

NODEPS
    This variable specifies a list of patterns that describes edges from dependency graph in targdep-prjdep:targ-prj or targ-prj:targ formats to be excluded from dependency graph. <M> []

NOSUBDIR
    If for some reason you want to exclude some subdirectories from build, list them in this variable. <U> []

OBJDIR_<dir>
    Value of ${.OBJDIR} inside dir subdirectory. Slash symbols inside <dir> are replaced with underlines. In addition, OBJDIR_<dir:T> variable is set to ${OBJDIR_<dir>} if ${SHORTPRJNAME} is "yes".

SRCDIR_<dir>
    Value of ${.CURDIR} inside dir subdirectory. Slash symbols inside <dir> are replaced with underlines. In addition, SRCDIR_<dir:T> variable is set to ${SRCDIR_<dir>} if ${SHORTPRJNAME} is "yes".

TARGETS
    A list of recursive targets. "Recursive" means that the target will be called for all subproject recursively (See mkc.subprj.mk and mkc.subdir.mk). <Im> [all, install, installdirs, uninstall, clean, cleandir, depends, test, configure, filelist, obj] By setting this variable in the Makefile one can add new targets for special purposes, for example, static code analysis, partial builds etc.

ALLTARGETS
    A list of targets for which pre_*, do_* and post_* counterparts exist, for example, pre_all, do_all and post_all. pre_* target runs before do_* target which in turn runs before post_*. Unless action is provided for do_* targets they implement the standard behaviour of mk-configure. No action is provided for targets pre_* and post_*, so they are for user's extensions. The standard behaviour for ${ALLTARGETS} may also be extended by adding new prerequisites to targets do_*.

SHORTPRJNAME
    If "yes", special targets with last component of the subprojects are provided. <Im> [yes]

MKRELOBJDIR
    If "yes", object directories ${OBJTOP}/dir are used. Unlike MAKEOBJDIRPREFIX object directories do not contain top-level ${.CURDIR} in paths. <Iu> [no]

SUBPRJSRCTOP
    This variables contains ${.CURDIR} directory and is passed to subprojects. <I> [${.CURDIR}]

mkc.subprj.mk provides the following targets:

<subdir> and <subdir:T>
    <subdir> is a subdirectory listed in SUBDIR or SUBPRJ. This target is equivalent to all-<subdir>. <subdir:T> means the last component of the directory and is created if ${SHORTPRJNAME} is "yes".

<target>-<subdir>
    Runs the specified <target> for the specified <subdir>. The target <target>-<subdir:T> is provided if ${SHORTPRJNAME} is "yes".

subdir-<target>-<subdir> and nodeps-<target>-<subdir>
    Runs the specified <target> for the specified <subdir> without dependencies. Targets subdir-<target>-<subdir:T> and nodeps-<target>-<subdir:T> are provided if ${SHORTPRJNAME} is "yes".

print_deps
    Outputs the dependency graph on targets in tsort(1) format taking NODEPS and NOSUBDIR variables into account.

  mkc.subdir.mk
The include file mkc.subdir.mk contains the default targets for building subdirectories. It provides the same targets as mkc.prog.mk. For all of the directories listed in the variable SUBDIR, the specified directory will be visited and the target made. There is also a default target which allows the command bmake <subdir> where <subdir>
 is any directory listed in the variable SUBDIR. As a special case, the use of a token .WAIT as an entry in SUBDIR acts as a synchronization barrier when multiple make jobs are run; subdirs before the .WAIT must complete before any subdirs after .WAIT are started. See bmake(1) for some caveats on use of .WAIT and other special sources. SUBDIR variable is provided as well as all variables provided by mkc.subprj.mk except SUBPRJ.

SUBDIR
    List of subdirectories <M> mkc.subprj.mk

  mkc.configure.mk
mkc.configure.mk is an auxiliary include file for checking platform's features like headers, function or variable declarations, function implementation in a particular libraries, data types sizes etc. This include file is included by mkc.prog.mk and mkc.lib.mk automatically but in some cases it makes sense to include it explicitly. mkc.configure.mk itself includes mkc.init.mk, then mkc.conf.mk , and finally internal include file which updates CPPFLAGS, CFLAGS, LDADD and SRCS. mkc.configure.mk supports the following variables.

MKCHECKS

MKC_CHECK_CUSTOM
    A list of custom checks (list of names). MKC_CUSTOM_FN.<custom_check_name> is a "C" or "C++" source filename or an executable program for your custom check, e.g., filename.c, filename.cc, subdir/filename.cxx, filename.C, filename.cpp or subdir/executable_script. mk-configure tries to compile or run the specified file and sets CUSTOM.<custom_check_name> variable to 1, 0 or other value. If MKC_CUSTOM_FN.<custom_check_name> is unset, it defaults to custom_check_name.c. Also -DCUSTOM_<CUSTOM_CHECK_NAME>=1 is added to CPPFLAGS if the specified check succeeded unless MKC_NOAUTO is set to 1 and MKC_CUSTOM_NOAUTO.<custom_check_name> is set to "yes". Here <CUSTOM_CHECK_NAME> is uppercase for <custom_check_name>. If MKC_CUSTOM_LINK.<custom_check_name> is "yes", then C or C++ source file is compiled and linked into executable. Also, CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS, LDADD, MKC_CUSTOM_CPPFLAGS.<custom_check_name>, MKC_CUSTOM_CFLAGS.<custom_check_name>, MKC_CUSTOM_CXXFLAGS.<custom_check_name>, MKC_CUSTOM_LDFLAGS.<custom_check_name> and MKC_CUSTOM_LDADD.<custom_check_name> flags are passed to the compiler.

        Find flex, bison, GNU awk, GNU m4 or GNU make respectively by analysing program's help and/or version messages. If found, BUILTIN.prog_<progname> is set to the path, otherwise it is set to empty string. Note that gawk may be found as awk, bison as yacc, gm4 as m4, flex as lex and gmake as make.

    prog_mkdep, prog_nbmkdep
        Find traditional BSD mkdep(1) or recent NetBSD version of it respectively.

    endianness
        BUILTIN.endianness variable is set to either little, big or unknown depending on a hardware.

MKC_REQUIRE_BUILTINS
    The same as MKC_CHECK_BUILTINS, but failure is treated as a fatal error (See configure target).

MKC_CHECK_PROGS
    List of <progname>s to check. As a result of the check bmake's variable HAVE_PROG.<progname> is set to either 1 (true) or 0 (false). Also PROG.<progname> is set to a full path of a program or to an empty string.
     Ex: MKC_CHECK_PROGS += lua ruby gawk runawk
     Res: HAVE_PROG.lua = 1
          PROG.lua = /usr/pkg/bin/lua
          HAVE_PROG.ruby = 0

    A list of checks (list of names) for C function prototypes. MKC_PROTOTYPE_FUNC.<name> is a C function prototype. MKC_PROTOTYPE_HEADERS.<name> is a list of headers separated by space or comma. mk-configure verifies that the specified prototype is correct and if so, HAVE_PROTOTYPE.<name> bmake variable is set to 1 and -DHAVE_PROTOTYPE_<NAME>=1 is added to CPPFLAGS unless MKC_NOAUTO is set to 1. Otherwise, HAVE_PROTOTYPE.<name> variable is set to 0. Ex.
      MKC_CHECK_PROTOTYPES = posix_iconv const_iconv
      MKC_PROTOTYPE_FUNC.posix_iconv =
        size_t iconv(iconv_t,char**,size_t*,char**,size_t*)

     CFLAGS += -DHAVE_PROTOTYPE_CONST_ICONV=1

MKC_REQUIRE_PROTOTYPES
    The same as MKC_CHECK_PROTOTYPES, but incorrect prototype is treated as a fatal error (See configure target).

MKC_CHECK_CC_OPTS
    A list of C compiler options to check. If ${CC} -c support the specified option, variable HAVE_CC_OPT.<option:S/=/_/g> is set to 1 and 0 otherwise. Double underline in the option is considered as a single space character. Ex.

MKC_CHECK_CCLD_OPTS
    Same as MKC_CHECK_CC_OPTS except that option "-c" is not passed to the compiler, so, executable is created. As a result HAVE_CCLD_OPT.<option:S/=/_/g> is set to 1 or 0.

MKC_CHECK_CXXLD_OPTS
    Same as MKC_CHECK_CCLD_OPTS but for C++ compiler. As a result HAVE_CXXLD_OPT.<option:S/=/_/g> is set to 1 or 0.

MKC_CACHEDIR
    Directory where intermediate and cache files are created. It defaults to ${.OBJDIR}. By default MKC_CACHEDIR variable is exported for subprojects. As a result cache files for subprojects are created in the top-level directory. If cache directory doesn't exist, it is created automatically.

MKC_SHOW_CACHED
    Setting it to 0 will hide
       Checking ... (cached) ... messages, that is, messages about fetching results from cache files.

MKC_DELETE_TMPFILES
    If set to 1, temporary files are removed.

MKC_NOCACHE
    All results are cached unless MKC_NOCACHE variable is set non-empty value

MKC_FEATURES
    This is a list of "features" required by project. In general, a feature is something that has problems with portability. This may be a function name or header missing on some platforms, for example. What developer needs to do is to add FEATURENAME to MKC_FEATURES variable and add #include <mkc_FEATURENAME.h> where it is needed. Internally, system requiremets are checked in the automatically included mkc_imp.f_FEATURENAME.mk file and all required actions (includes, define checks etc.) are made in mkc_FEATURENAME.h header file. Currently the following features are provided:

    arc4random
        This feature provides arc4random(3), arc4random_buf(3) and arc4random_uniform(3) functions available in BSDs. If these functions are absent on your system, install libbsd library.

    bswap
        This feature provides bswap16(3), bswap32(3) and bswap64(3) functions available in *BSD.

    dprintf
        This feature provides dprintf(3).

    efunc
        This feature provides esetfunc(3), efopen(3), ecalloc(3), emalloc(3), erealloc(3), estrdup(3), estrndup(3), estrlcpy(3), estrlcat(3), easprintf(3), and evasprintf(3) functions from NetBSD.

    err This feature provides err(3), errx(3), verr(3) and verrx(3) BSD-isms.

    errc
        This feature provides errc(3) and verrc(3) BSD-isms.

    fgetln
        This feature provides fgetln(3) BSD-ism.

    fts This feature provides fts_open(3), fts_read(3) etc. functions available on BSDs and Linux. If it is absent on your system, you have to install libfts (both headers and library). libfts is a part of musl project.

    getdelim
        This feature provides getdelim(3) from POSIX.

    getline
        This feature corresponds to getline(3) function which is a part of POSIX2008 unavailable on some systems. mkc_imp.f_getline.mk checks whether getline declaration is available in stdio.h and implementation is available in libc. If not, getline.c provided by mk-configure is added to SRCS and declaration is provided in mkc_getline.h header.

    libdl
        This feature checks whether libdl library is available and dlopen(3) is declared in dlfcn.h. If yes, -ldl is added to LDADD. mkc_libdl.h provides declarations for dlopen(3), dlsym(3), dlclose(3) etc.

    libl
        Adds -ll or -lfl to LDADD depending on which one is available. One can use this feature instead of LIBLEX variable.

    libm
        This feature checks whether libm is available and if yes, adds -lm to LDADD. Most UNIX-like systems have libm but Haiku, for example, does not. mkc_imp.f_libm.mk checks whether libm library is available and if yes, -lm is added to LDADD.

    posix_getopt
        It is well-known that glibc getopt(3) does not conform to POSIX by default. This feature provides POSIX-ly correct getopt.

    progname
        This feature provides getprogname(3) and setprogname(3) functions available in *BSD.

    raise_default_signal
        This feature provides function raise_default_signal(3) from NetBSD.

    RB SPLAY
        BSD systems provide sys/tree.h header where RB_* and SPLAY_* macroses are defined for red-black tree and splay. These features check whether sys/tree.h and appropriate macroses are available.
