MKC_CHECK_CUSTOM(1)                                        MKC_CHECK_CUSTOM(1)

NAME
       mkc_check_custom - run user's custom checks.

SYNOPSIS
       mkc_check_custom [-r] sourcefile
       mkc_check_custom cmd [args...]
       mkc_check_custom -h

DESCRIPTION
       If cmd is executable mkc_check_custom runs cmd args.  Otherwise it
       tries to compile sourcefile and output 1 if compilation succeeded and 0
       otherwise.  If -r option was applied it runs a compiled program.  What
       type of compiler to use depends on sourcefile extension. '.c'
       corresponds to ${CC} (C language), '.cc', '.cxx', '.C' and '.cpp'
       correspond to ${CXX} (C++ language), '.f' -- to ${FC} (Fortran).

OPTIONS
       -h     Display help message.

       -r     Run executable compiled from sourcefile.

       -p text
              Prefix of the generated cache file. The default is "custom".

       -n text
              Name part of the generated cache file.
              The default is `basename <sourcefile>`.

       -m text
              Message mkc_check_custom outputs.
              The default is "custom test sourcefile_or_cmd".

       -s     mkc_check_custom outputs an exit status of cmd args.

       -d     Delete cache files.

       -e     Print 0 if compiler/cmd print something to stderr.

       -b     Print yes/no instead of 1/0.

ENVIRONMENT
       CC     C compiler

       CXX    C++ compiler

       CARGS  Options passed to compiler (CC, CXX or FC)

       FC     Fortran compiler

       CPPFLAGS
              Preprocessor flags for C and C++

       CFLAGS Compilation flags for C

       CXXFLAGS
              Compilation flags for C++

       FFLAGS Compilation flags for Fortran

       MKC_VERBOSE
              If set to 1, verbose messages are output to stderr.

       MKC_SHOW_CACHED
              If set to 1 and MKC_VERBOSE is set to 1, cached results are
              output to stderr.

       MKC_CACHEDIR
              Directory where temporary and cache files are created.  If unset
              they are created in a current directory.

       MKC_NOCACHE
              All results are cached unless MKC_NOCACHE variable is set to 1.

       MKC_DELETE_TMPFILES
              If set to 1, temporary files are removed.

EXAMPLES
          mkc_check_custom alloca_in_stdlib.c
          mkc_check_custom custom_checks/cxx_foo_test.cc
          mkc_check_custom /full/path/to/yacc_need_liby
