x11-misc/compose-tables-1.7.1 compiles on my amd64 system (GCC-10)
x11-misc/compose-tables-1.7.0 compiles in my ~amd64 chroot (GCC-11)

checking for cpp... no

Are you using [-native-symlinks]?

I see libX11 already has a fix for this, but compose-tables didn't inherit it.

Just needs CPP="$(tc-getPROG CPP cpp)" added to CONFIGURE_OPTIONS + inherit

And uh, not in global scope in case anyone went too quick with this.

Yes, but it fails with symlinks too.

Are you sure? Is it still not finding cpp?

1.7.1 + gcc11 + ~amd64 + symlinks is fine for me, only fails if I remove /lib/cpp and /usr/bin/cpp

Comment 10 tastytea 2021-05-22 03:51:46 UTC

Oh right, I overlooked /usr/bin/cpp in my workaround-script. 🤦 It works with /usr/bin/cpp.
