1 # SYNOPSIS 2 # 3 # MHD_CHECK_ADD_CC_LDFLAG([FLAG-TO-TEST], [VARIABLE-TO-EXTEND], 4 # [ACTION-IF-SUPPORTED], [ACTION-IF-NOT-SUPPORTED]) 5 # 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]) 19 # 20 # 21 # LICENSE 22 # 23 # Copyright (c) 2022 Karlson2k (Evgeny Grin) <k2k@narod.ru> 24 # 25 # Copying and distribution of this file, with or without modification, are 26 # permitted in any medium without royalty provided the copyright notice 27 # and this notice are preserved.
