protobuf-c emerge fails (solved)

[mikb]

Current versions of dev-libs/protobuf-c depend on C++17. I am unable to upgrade or rebuild =dev-libs/protobuf-c-1.4.1-r1 because of a configure failure:

Code: Select all

checking whether x86_64-pc-linux-gnu-g++ -m32 -mfpmath=sse supports C++17 features with -std=c++17... no
checking whether x86_64-pc-linux-gnu-g++ -m32 -mfpmath=sse supports C++17 features with +std=c++17... no

checking whether x86_64-pc-linux-gnu-g++ -m32 -mfpmath=sse supports C++17 features with -h std=c++1z... no
configure: error: *** A compiler with support for C++17 language features is required.

Checking the config.log, it seems the compiler command for the C++17 standard check is being overridden:

Code: Select all

configure:17902: checking whether x86_64-pc-linux-gnu-g++ -m32 -mfpmath=sse supports C++17 features with -std=c++17
configure:18697: x86_64-pc-linux-gnu-g++ -m32 -mfpmath=sse -std=c++17 -c -march=native -O3 -pipe -frecord-gcc-switches -std=gnu++11  conftest.cpp >&5

The summary at the end of the config.log has:

Code: Select all

CXXFLAGS='-march=native -O3 -pipe -frecord-gcc-switches -std=gnu++11'

but the CXXFLAGS in emerge --info is:

Code: Select all

CXXFLAGS="-march=native -O3 -pipe -frecord-gcc-switches -std=gnu++17"

I can't see where this is being overridden. Does anyone have any suggestions?

The entire config.log is too big to post here, but this is the first time the log references --std=gnu++11:

Code: Select all

configure:14539: checking whether the x86_64-pc-linux-gnu-g++ -m32 -mfpmath=sse linker (x86_64-pc-linux-gnu-ld -m elf_i386) supports shared libraries
configure:15619: result: yes
configure:15655: x86_64-pc-linux-gnu-g++ -m32 -mfpmath=sse -c -march=native -O3 -pipe -frecord-gcc-switches -std=gnu++11  conftest.cpp >&5

[Ionen]

Code: Select all

CXXFLAGS="-march=native -O3 -pipe -frecord-gcc-switches -std=gnu++17"

Please don't pass -std globally, it tend to mess with things (e.g. if something needs c++20, or is broken with newer std and then yours overrides the flag it's trying to pass). gnu++17 is either way the default with current GCC.

That aside, I don't see anything in the ebuild or protobuf-c that would override that (it builds fine with these CXXFLAGS for me).

Do you have anything in /etc/portage/package.env or /etc/portage/bashrc?

I appreciate the advice, and have adjusted my make.conf appropriately.

Thank you, package.env was the problem. At some time in the past, it must have been necessary to emerge dev-libs/protobuf and dev-libs/protobuf-c using -std=gnu++11, and I had forgotten about it.
