ANN: mk-configure-0.26.0

[Aleksey Cheusov <cheusov%tut.by@localhost>]

I've released mk-configure-0.26.0.

In short, this is a bmake-based build system with functionality similar
to autotools, cmake etc. As it is based on bmake and shares the same
design principles (well, more or less) as BSD mk files I believe it can
be a friendly build system for BSD developers who develop portable
software.

Version 0.26.0 is available in pkgsrc (devel/mk-configure). Older
versions are available in FreeBSD, Debian, AltLinux and maybe others.

Major changes in latest two releases is below.

======================================================================
Version 0.26.0, by Aleksey Cheusov, Mon,  3 Feb 2014 00:32:51 +0300

  "Features" framework was implemented (variable MKC_FEATURES).  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: strlcat, strlcpy,
  getline, libm, libdl, RB, SPLAY, SLIST, SIMPLEQ, STAILQ, LIST, TAILQ
  and CIRCLEQ. Original idea was stolen from pkgsrc.

  mkc_imp.pkg-config.mk:
    - New variables MKC_CHECK_PKGCONFIG and MKC_REQUIRE_PKGCONFIG were
      introduced.  They work just like other MKC_{CHECK,REQUIRE}_*
      variables from mkc.configure.mk. Thanks to Andrew Shadura for
      pushing me to this direction.

  mkc.configure.mk:
    - MKC_{CHECK,REQUIRE}_PROTOTYPES were introduced.  With their help
      mk-configure is able to check C function prototypes.  This
      feature was proposed by Andrew Shadura.

  If ${MKC_CACHEDIR} does not exit, it is automatically created.

  ${SRCTOP}/Makefile.common is included by all subprojects if it
  exists. It can be used as a replacement or addition for
  ../Makefile.inc.

  Valiables SRCDIR_<dir>, SRC_PATHADD, MKC_SOURCE_DIR, LDFLAGS0 and
  LDADD0 were introduced.

  Wrongly named builtin 'endianess' was renamed to 'endianness'.
  Thanks to Andew Shadura for the report and fix!

  mk-configure itself is now 2-level project.
  This allows me to run an arbitrary regression test like the following
     bmake test-examples/hello_world
  Hurray! :-)

  mkc.subprj.mk:
    - Now it works correctly if NOSUBDIR is not empty.
      Also, NOSUBDIR affects NODEPS and therefore the dependency graph.
    - New target "print-deps" that outputs the dependency graph was
      introduced.

  -O is added to CFLAGS if USE_FORT==yes, seen on Linux/ppc64/gcc

  Documentation: clean-ups, grammar fixes, minor improvements.

  Fix. Some @@ patterns in mk-configure.7 should not be replaced with
  directories. Thanks to Andrew Shadura for the report!

  This release was successfully tested on the following platforms:
  NetBSD-6.1/amd64, FreeBSD-8.3/amd64, OpenBSD-{4.9,5.3}/x86,
  DragonFlyBSD-3.4/x86, Linux/{x86,amd64}, SunOS-5.10/sparc,
  SunOS-5.11/x86.

Version 0.25.0, by Aleksey Cheusov, Wed,  1 Jan 2014 19:28:55 +0300

  Build infrastructure for mk-c itself was completely reimplemented.
  Now it looks much better and is more flexible for further extensions.

  NetBSD version of mkdep(1), traditional BSD mkdep(1) or
  makedepend(1) is needed at build time.

  LDCOMPILER defaults to "yes".

  Variable TARGETS is now visible to users and is documented. It
  contains all recursive targets and may be used for adding user's
  functionality to mk-c.

  FIX: Parallel installation ("mkcmake install -jN") now works
  correctly. "installdirs" is activated before "install". Report by
  Michael Crogan.

  During build object directories are created automatically by default
  when MAKEOBJDIR or MAKEOBJDIRPREFIX are set.  New recursive target
  "obj" and variable MKOBJDIRS were introduced.
  Report by Michael Crogan.

  New variable MKRELOBJDIR was introduced. With its help one can
  create object directories relative to top-level object directory
  (like MAKEOBJDIRPREFIX but without top-level ${.CURDIR} in paths).
  Thanks to Michael Crogan.

  target "depend":
     - FIX. Original implementation relied on NetBSD version of
       mkdep(1). So, it didn't work on Linux, FreeBSD and others with
       original BSD mkdep(1). Type of mkdep(1) is detected at
       mk-configure build time. Report by Michael Crogan.

  New variables LN, LN_S, MKDIR, RM, CLEANFILES_CMD, CLEANDIRS_CMD,
  UNINSTALL, MAKEDEPEND, OBJTOP, CC_PREFIX, CXX_PREFIX were
  introduced.

  New variable NODEPS was introduced. With its help one can cut off
  the dependency graph for particular targets.

  New variable BMAKE_REQD was introduced.

  New variable SRCTOP was introduced. With its help
     "mkcmake -C subdir target" may work just like "mkcmake target-subdir".

  New variables CFLAGS.dflt.${CC_TYPE} and CXXFLAGS.dflt.${CXX_TYPE}
    were introduced. They default to -Qunused-arguments
    for clang and clang++.

  mkc.init.mk can be invoked by users directly for setting all
  required variables and further checks (CC_TYPE, LD_TYPE, OPSYS etc.).

  mkc_imp.links.mk:
     - This module was reimplemented from scratch.
       Bug with parallel installation (LINKS and MLINKS) was fixed.

  mkc.minitest.mk:
     - new variable TEST_PREREQS was introduced.

  mkc_imp.inc.mk: fix for ${INCS} installation problem happened when
     headers are built in ${.OBJDIR}. Report by Jan Smydke.

  mkc_imp.info.mk:
     - fix for MKINSTALL=no. "installdirs" unexpectedly created target
       directories.

  mkc.configure.mk:
     - fix issue with MKC_CHECK_CUSTOM when ${.OBJDIR} != ${.CURDIR}
     - MKC_CHECK_PROGS: PROG.<prog> is set even if full path was
       specified.  In addition existence and executability of the
       specified file is always checked.
     - fix for MKC_SOURCE_FUNCLIBS. Not all objects were cleaned
       correctly by target "clean".  Now objects are added to CLEANFILES
       unconditionally.
     - negative results for MKC_REQUIRE_* are not cached.  This gives
       users ability to fix the problem by changing the environment
       and try again.
     - MKC_CHECK_BUILTINS. Additional builtin checks were added:
       "prog_mkdep" and "prog_nbmkdep" for original BSD mkdep(1) and
       NetBSD version of mkdep(1) respectively.

  mkc_imp.intexts.mk fixes:
     - Targets "clean" and "cleandir" do not fail anymore if INTEXTS_REPLS
       contains empty variables.
     - Target "all" works correctly if INFILES or INSCRIPTS contain
       files with directories.

  mkc.sub{dir,prj}.mk:
     - ${MAKEFLAGS} is passed to recursive ${MAKE}s.
     - {nodeps-,subdir-,}dir:T are also targets, that is, one can also
       use the last component of subdirectory as_a_part_of/as_a_whole
       target. If you want to disable this, set SHORTPRJNAME to "no".

  mkc_imp.subdir.mk was reimplemented using mkc_imp.subprj.mk

  mkc_imp.dep.mk:
     - documentation for this module was added.
     - support for SHRTOUT=yes
     - new variable DPSRCS was introduced
     - MKDEP_SUFFIXES also contains .os and .op. Report by Michael Crogan.
     - Target "clean" does not remove .depend and .d files.
       Target "cleandir" does. NetBSD mk files work the same way.
       Report by Michael Crogan.

  MKPIE/SHLIB_*:
     - s/-KPIC/-xcode=pic32/ for SunStudio compilers

  MKSSP=yes:
     - Support for IBM XL Compiler was added (not tested due to lack of such 
iron)
     - Support for Intel C/C++ Compiler was added

  Documentation fixes, updates and improvements.  A lot of new
  examples/. A lot of new regression tests.

  Tools:
     Long option --help was removed from all utilities
     - mkc_install:
        - fix for problem with parallel "installdirs" (race condition).
        - Options -t and -b were removed.
     - mkc_check_prog: option -i is documented in man page
     - mkc_check_compiler: workarounds for buggy SunStudio C++
       compiler ("CC -E -" exits with error).

  All test are run with MKCATPAGES=no by default.

  myprojects.pdf: pipestatus also uses mk-configure.
