# SYNOPSIS # # MHD_CHECK_CC_LDFLAG([FLAG-TO-TEST], [VARIABLE-TO-PREPEND-LDFLAGS], # [ACTION-IF-SUPPORTED], [ACTION-IF-NOT-SUPPORTED]) # # DESCRIPTION # # This macro checks whether the specific compiler flag is supported. # The check is performing by prepending FLAG-TO-TEST to LDFLAGS, then # prepending value of VARIABLE-TO-PREPEND-LDFLAGS (if any) to LDFLAGS, and # then performing compile and link test. If test succeed without warnings, # then the flag is considered to be supported. Otherwise, if compile and link # without test flag can be done without any warning, the flag is considered # to be unsuppoted. # # Example usage: # # MHD_CHECK_CC_LDFLAG([-pie], [additional_LDFLAGS], # [additional_LDFLAGS="${additional_LDFLAGS} -pie"]) # # Defined cache variable used in check so if any test will not work # correctly on some platform, user may simply fix it by giving cache # variable in configure parameters, for example: # # ./configure mhd_cv_cc_fl_supp__wshadow=no # # This simplify building from source on exotic platforms as patching # of configure.ac is not required to change results of tests. # # LICENSE # # Copyright (c) 2022 Karlson2k (Evgeny Grin) # # Copying and distribution of this file, with or without modification, are # permitted in any medium without royalty provided the copyright notice # and this notice are preserved.
