The older x86_64 GCC6 toolchain had a multilib patch which allowed it to compile to i386 (32-bit) machine code, which is why it worked fine. However, the x86_64 GCC8 toolchain does not have the aforementioned patch and fails.

Definitely, you should be able to, but you need crossgcc-i386 to build coreboot for x86 platforms. thanks, > salvatore > Best regards, Angel Pons >
