MKC_CHECK_HEADER(1) MKC_CHECK_HEADER(1) NAME mkc_check_header - detects presense of header file. SYNOPSIS mkc_check_header [OPTIONS] <headers> DESCRIPTION mkc_check_header detects presense of header file. As a result it prints either 1 (true) or 0 (false) to stdout. headers may be either a single header file or a list of headers separated by comma. In this case all mentioned headers are put into a single .c file and ${CC} is run. By default $CC -c is used for checking. By default, temporary and cache files _mkc_header_lheader_h.{c,err,res} are created under MKC_CACHEDIR directory. Here, lheader_h is the last header from comma- separated list headers. OPTIONS -h Display help message. -e Use $CC -E for checking instead of $CC -c. -d Delete cache file. ENVIRONMENT CC Compiler. By default cc is used. CPPFLAGS, CFLAGS Options passed to the compiler. 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 out- put 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.
