link spec [1][2] is empty on x86_64-elf-gcc, i.e. -m32 is not propogated to the linker as "-m elf_i386" and that causes the error: /usr/local/opt/x86_64-elf-binutils/bin/x86_64-elf-ld: i386 architecture of input file `x86/realmode.o' is incompatible with i386:x86-64 output 1. https://gcc.gnu.org/onlinedocs/gcc/Spec-Files.html 2. https://gcc.gnu.org/onlinedocs/gccint/Driver.html Cc: Cameron Esfahani <dirty@apple.com> Signed-off-by: Roman Bolshakov <r.bolshakov@yadro.com> --- x86/Makefile.common | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
