I am trying to create a cross-compiler arm-elf-gcc.
So, I installed binutils 2.18 with the following settings:
./configure --target=arm-elf --enable-interwork --enable-multilib
This seems to be normal.
next I installed gmp, mpfr and libmpc
so now to gcc itself.
// edit - deleted the previous error and updated from the current one (I tried to build everything separately)
First I install bootstrap gcc with these settings:
--target=arm-elf --disable-libssp --with-newlib --without-headers --with-gnu-as --with-gnu-ld
And after that I try to create newlib 1.17.0 with it
--target=arm-elf --disable-werror --disable-newlib-supplied-syscalls --disable-nls --with-gnu-as --with-gnu-ld
But this still leads to the same error. Maybe newlib is trying to build for the x86 architecture with the gcc apple (I do all this on OS X), which may not understand these options?
