--- Comment #1 from Iain Buclaw <ibuclaw at gdcproject dot org> --- (In reply to Iain Buclaw from comment #0) > Configuring with --target=arm-wrs-vxworks7 --with-cpu=arm8 and the selftests > pass. > I was going to ignore that you need to set VSB_DIR in order for the selftests to pass, however I've stumbled across this comment in gcc/Makefile.in, which seems to suggest that perhaps it should "just work" without. # GCC's selftests. # Specify a dummy input file to placate the driver. # Specify -nostdinc to work around missing WIND_BASE environment variable # required for *-wrs-vxworks-* targets.
