Hi, when I try to build librecmc, it fails with some error while trying to build the toolchain. I'm currently using GCC 9.3.0, but could try a different GCC major version if I knew which one(s) are supported.

Not sure how much additional info you care about at this point, but here is the system information and then the errors:

Hi, when I try to build librecmc, it fails with some error while trying to build the toolchain. I'm currently using GCC 9.3.0, but could try a different GCC major version if I knew which one(s) are supported.

libreCMC v1.5.x has been built using gcc 5.4 (Trisquel 8 / ubuntu 16.04), 7.3.0 (Trisquel 9 / ubuntu 18.04) and 9.3.0 (ubuntu 20.04 / Fedora 31). I've also built it using GCC 10.1 with a few patches.

Am getting the same errors building with GCC 7.5.

From the error output, seems that functions being built for the librecmc gcc-toolchain are conflicting with the declarations in the host gcc-toolchain. Presumably my environment must be missing some kind of flag or something that prevents that. Guess I'll have to get myself educated on how gcc compiles itself without these conflicts.
