GCC needs -Wno-unused-function in CXXFLAGS to build this port.

While here, add USES=localbase:ldflags.

Tested on powerpc64 and amd64.

Hardware sponsored by IntegriCloud.

After update to 1.1.0, USES alone is not enough.

I don't see an issue, though maybe a cleaner approach can be used, there is momentum to use variables rather than conditional tests.

Currently we can use CXXFLAGS_${ARCH}, which might be enough in this situation. Maybe using CXXFLAGS_${CHOSEN_COMPILER_TYPE} is something that could also be added to the infrastructure.

You could manually be arch/compiler specific - based on usage from devel/godot -

CXXFLAGS_powerpc64_gcc=	-Wno-unused-function

After upgrade to GCC 8, there are additional errors and -Wno-error for GCC builds is necessary.

maintainer update for graphics/opencolorio

Testing the existence of libstdc++.so installed by the base system isn't foolproof, a user can configure to use GCC for building ports (FAVORITE_COMPILER=gcc). Not sure how popular this is, or reliable, I found the need to manually set CC/CXX to get gcc used on amd64.

Does setting CXXFLAGS this way work on gcc built ARCHs?

I doubt that any of these flags need adjusting based on ARCH or base compiler, it is really about chosen compiler at build time.

If this fails, I think testing chosen compiler in place of the lib test would be better.

  graphics/opencolorio: fix build with GCC-based architectures

  Add -Wno-unused-function -Wno-error to CXXFLAGS when using GCC.

  While here, add USES=localbase:ldflags.
