For all those who can cursed the inability of gprconfig to find the ada runtime, a fix has been pushed into the gcc sources, https://github.com/gcc-mirror/gcc/commit/9467e7331188705ec16c086b77e1809c5b0aab7d.

Basically, with 'gcc --dumpmachine' would return something like 'x86_64-pc-linux', but the runtime file s-oscons.ads said it was 'x86_64-pc-linux-gnu' giving a mismatch and the runtime never being found.

After modifying compilers.xml to hunt in ../lib(.+)?/ since files are 64bit under lib64, I've built gcc-11, gprbuild & xmlada all without issues. Hooray...

Must be one of the longest gubs in gnat...

On Gentoo, it is x86_64-pc-linux-gnu:

ls /usr/x86_64-pc-linux-gnu/
bin binutils-bin gcc-bin i686-w64-mingw32 lib x86_64-w64-mingw32

gcc -dumpmachine
x86_64-pc-linux-gnu

How does this affect us?

On suse it's x86_64-suse-linux. If you were to build on redhat, it would be x86_64-redhat-linux. They would fail. I'm sure there are others.

That doesn't answer my question. I asked whether this change will flip
it in the other direction and fail for distributions which use the -gnu
part at the end like gentoo does.

If so, that's not a fix.
