SYNOPSIS
mkc_check_custom [-r] sourcefilemkc_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.

-
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.

- 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.
