Uhu - HOSTCC is the native compiler, which very likely does not know anything about 405 cpus... > then I put -march=405 and give this errors: > > scripts/basic/fixdep.c:1: error: bad value (405) for -march= switch > scripts/basic/fixdep.c:1: error: bad value (405) for -mtune= switch > make[1]: ** [scripts/basic/fixdep] Erro 1 > make: ** [scripts_basic] Erro 2 Still, same problem - you want to use the flag for the cross compiler. > See a piece of my Makefile: > > HOSTCC = gcc > HOSTCXX = g++ > HOSTCFLAGS = -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer > -march=405 > HOSTCXXFLAGS = -O2 Again, this is the host compiler. > How can I do this? If we are only talking about compiling a recent linux kernel, then the easiest way is to simply override CFLAGS_KERNEL from the commandline, i.e.: make CFLAGS_KERNEL=-mcpu=405 uImage If you want to check that this works, do a make CFLAGS_KERNEL=-mcpu=405 V=1 uImage and check the generated command lines.
