# SYNOPSIS # # MHD_CHECK_ADD_CC_LDFLAGS([FLAGS-TO-TEST], [VARIABLE-TO-EXTEND]) # # DESCRIPTION # # This macro checks whether the specific compiler flags are supported. # The FLAGS-TO-TEST parameter is whitespace-separated flagto to test. # The flags are tested one-by-one, all supported flags are added to the # VARIABLE-TO-EXTEND. # Every flag check is performing by appending one flag to the value of # VARIABLE-TO-EXTEND (LDFLAGS if not specified), then prepending result to # LDFLAGS (unless VARIABLE-TO-EXTEND is LDFLAGS), and then performing compile # and link test. If test succeed without warnings, then the flag is added to # VARIABLE-TO-EXTEND. Otherwise, if compile and link without test flag cannot # be done without any warning, the flag is considered to be unsuppoted. # # Example usage: # # MHD_CHECK_ADD_CC_LDFLAGS([-W,--strip-all -Wl,--fatal-warnings], # [additional_LDFLAGS]) # # # 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.
