aom @3.12.1_0: C++ versions less than C++14 are not supported

This is the first error that I see, which makes no sense to me since my OS was just offically patched yesterday.

arm64 Sequoia 15.6.1

clang++ --version
Apple clang version 17.0.0 (clang-1700.0.13.5)
Target: arm64-apple-darwin24.6.0

This is a build on an older MacOS. So I think the issue isn't the latest MacOS.

[lukaso (Lukas Oberhuber)]

That build was in Rosetta 2 x86_64 on arm.

[jmroot (Joshua Root)]

The build is using -std=c++11 and one of the included headers (from gtest) wants at least C++14.

[ryandesign (Ryan Carsten Schmidt)]

But aom doesn't depend on the gtest port and the error says:

:info:build In file included from /opt/local/var/macports/build/aom-e880fda7/work/aom-3.12.1/third_party/googletest/src/googletest/src/gtest-all.cc:38:

:info:build   279 | #error C++ versions less than C++14 are not supported.
:info:build       |  ^

So it's trying to build a bundled copy of google test (presumably an older version that doesn't require C++14) but is inadvertently finding the headers of MacPorts gtest (which error when told by aom to use C++11 since they require C++14 or newer).

sudo port -f deactivate gtest and sudo port clean aom would theoretically work around the problem.

Hi Ryan;

Your suggestion appears to work fine, as aom installed without complaint after the gtest deactivate and aom clean. I have not re-activated gtest (yet).

Thanks, Ken Wolcott

[lukaso (Lukas Oberhuber)]

Does this mean the two packages are incompatible? Or is this just a temporary workaround?

[ryandesign (Ryan Carsten Schmidt)]

It's a bug in the aom port that should be fixed so that the workaround is no longer needed.

[Dave-Allured (Dave Allured)]

@ryandesign what do you suggest? Configure "aom" to always disable the bundled "gtest"?

[kwolcott]

I have successfully installed aom some time ago.
