I actually use LD in a makefile. I use the value of LD to choose between the gcc CFLAGS options "-fuse-ld=bfd", "-fuse-ld=gold" or "-fuse-ld=lld" In my youth, I actually wrote my own linking rules to invoke the linker directly, but, I don't have time for that anymore. ;-) -Mike Gran _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
