6 | # DESCRIPTION | ||
7 | # | ||
8 | # This macro checks whether the specific compiler flag is supported. | ||
9 | # The check is performing by appending FLAG-TO-TEST to the value of | ||
10 | # VARIABLE-TO-EXTEND (LDFLAGS if not specified), then prepending result to | ||
11 | # LDFLAGS (unless VARIABLE-TO-EXTEND is LDFLAGS), and then performing compile | ||
12 | # and link test. If test succeed without warnings, then the flag is added to | ||
13 | # VARIABLE-TO-EXTEND. Otherwise, if compile and link without test flag cannot | ||
14 | # be done without any warning, the flag is considered to be unsuppoted. | ||
15 | # | ||
16 | # Example usage: | ||
17 | # | ||
18 | # MHD_CHECK_ADD_CC_LDFLAG([-pie], [additional_LDFLAGS]) | ||
