[Help needed] Possible change from gcc failed both openxr and luxcorerender

[Luya Tshimbalanga]

Due to a possible change related to GCC, packages like openxr and 
luxcorereneder failed to build with these errors:

I don't think there's any relevant change in GCC.

It looks like these packages simply fail to link with -lstdc++fs (or
they have that flag in the wrong position in the link command, it
needs to be after any objects that depend on it).

The error for this build is completely different to the errors you
showed above:
/builddir/build/BUILD/LuxCore-luxcorerender_v2.5/include/luxrays/utils/utils.h:40:18:
error: 'std::std' has not been declared
    40 | #define isinf(f) std::isinf(f)
       |                  ^~~

That's a bug in the source package.

This one has the errors above, and there is no sign of -lstdc++fs in
the linker command. It's a package bug.

What will be the suggestion to address that issue before contacting 
upstream luxcorerender?

You are right. I managed to solve the issue for openxr.

Replace the silly macro above with something like:

using std::isinf;
