mkc_check_header - Man Page

mkc_check_header [Options] <headers>

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.

-h

Display help message.

-e

Use $CC -E for checking instead of $CC -c.

-d

Delete cache file.

CC

MKC_VERBOSE

MKC_SHOW_CACHED
