coreboot

Hi all,

Thank you for coreboot, first of all.

I am looking for building coreboot with u-boot payload.
I started from scratch as documented on my Fedora 44 beta system.

I hit the error below, -please scroll-down for it- and hoping that
someone already either fixed or done a workaround for this making
crossgcc-i386.

I somewhat did workaround for -V command-line argument error for
gnatgcc and g++, and got version info out there, but no lock for
this error: no matching function for call to 'S2C(const char8_t [2]) .

I attached config&build log from util/crossgcc/build-i386-elf-GCC.

Welcome to the coreboot cross toolchain builder v2026-01-30_235bb1e617

Building toolchain using 10 thread(s).

Target architecture is i386-elf

Found compatible Ada compiler, enabling Ada support by default.
