Problem in building the toolchain with gcc-8.1

June 5, 2018

      Hello everyone,

I currently having a problem build the toolchain from a freshly checkout
coreboot repository. I've tried to build with different options: For
example with all platforms and only with i386 support. Multi core
(CPUS=4) and with a single core. Here an example build:

Building toolchain using 1 thread(s).

Target architecture is i386-elf

Found compatible Ada compiler, enabling Ada support by default.

I also tried to do this with clang, with similar result.

Here is the log from clang:

A look into the build log from GCC seems to disclose a similar error:

I'm using ArchLinux with a Linux kernel 4.16.13-1 and gcc 8.1.0-1,
gcc-ada 8.1.0-1

I checkout the git code in different version (4.8, 4.8.1, latest master
commit). I quite sure that's the problem is the compiler. However I do
not know how to fix this in the moment.

I added the compressed logs from the  i386-elf build. Hope this can
help. Thank you for reading.

best regards,
