"Fatal error: no compiled in support for x86_64" when building GCC #5

Closed iamgreaser closed 1 year ago

Using Void Linux, GCC 10.2.1, Binutils 2.32.0.20190814.

g++ in general works fine outside of this situation, even with most of those flags defined.

Of course, running this directly, outside of the build system, results in the same error:

Sounds like a system issue? But why would it be invoking a non-64-bit GNU assembler?

Hello @iamgreaser,

Indeed this sounds to me like a problem with the underlying host GCC setup. Are you able to compile a simple "Hello world" program using g++?

Thank you!

Hello @iamgreaser,

Strange. Perhaps try adding a -v option to your above command line (for building build/genmddeps.o)? This should give an idea of what programs the GCC driver is running for the individual compiler passes.

Thank you!

Can you try now? I fixed an embarassing typo in build.sh.
