The checking is stopped when the first 12 # supported flag found. 13 # The checks are performing by appending FLAGx-TO-TEST to the value of 14 # VARIABLE-TO-EXTEND (LDFLAGS if not specified), then prepending result to 15 # LDFLAGS (unless VARIABLE-TO-EXTEND is LDFLAGS), and then performing compile 16 # and link test. If test succeed without warnings, then the flag is added to 17 # VARIABLE-TO-EXTEND and next flags are not checked. If compile-link cycle 18 # cannot be performed without warning with all tested flags, no flag is 19 # added to the VARIABLE-TO-EXTEND. 20 # 21 # Example usage: 22 # 23 # MHD_CHECK_CC_LDFLAG([additional_LDFLAGS], 24 # [-Wl,--strip-all], [-Wl,--strip-debug]) 25 # 26 # Note: Unlike others MHD_CHECK_*CC_LDFLAG* macro, this macro uses another 27 # order of parameters. 28 # 29 # LICENSE 30 # 31 # Copyright (c) 2022 Karlson2k (Evgeny Grin) <k2k@narod.ru> 32 # 33 # Copying and distribution of this file, with or without modification, are 34 # permitted in any medium without royalty provided the copyright notice 35 # and this notice are preserved.
