Some Boost 1.67 packages are using the cxx11 ABI, when compiler.libcxx=libstdc++

Description of Problem, Request, or Question

Some Boost 1.67 packages have

Package Details (Include if Applicable)

• Package Name/Version: boost_*/1.67.0
• Operating System: CentOS 6
• Compiler+version: GCC 7.3.1 (from devtoolset-7)
• Docker image: N/A

Steps to reproduce (Include if Applicable)

Unfortunately, the program I'm working on is proprietary, but I'll try to include as much detail as I can.

In function `boost::unit_test::make_test_case(boost::function<void ()> const&, boost::unit_test::basic_cstring<char const>, boost::unit_test::basic_cstring<char const>, unsigned long)':
/home/kam/.conan/data/boost_test/1.67.0/bincrafters/stable/package/39c592edeadc17fab29689acb950103193c0b674/test/include/boost/test/tree/test_unit.hpp:249: undefined reference to `boost::unit_test::ut_detail::normalize_test_case_name(boost::unit_test::basic_cstring<char const>)'

If I look at the library, it has abi:cxx11

$ nm -C /home/kam/.conan/data/boost_test/1.67.0/bincrafters/stable/package/39c592edeadc17fab29689acb950103193c0b674/test/lib/libboost_unit_test_framework.a | grep normalize_test_case_name
000000000000227f T boost::unit_test::ut_detail::normalize_test_case_name[abi:cxx11](boost::unit_test::basic_cstring<char const>)

Any insights you can offer will be welcome.

... but the referencing object does not.

                 U boost::unit_test::ut_detail::normalize_test_case_name(boost::unit_test::basic_cstring<char const>)

The Conan package says it's using libstdc++ (not 11):

$ more /home/kam/.conan/data/boost_test/1.67.0/bincrafters/stable/package/39c592edeadc17fab29689acb950103193c0b674/conaninfo.txt
[settings]
    arch=x86_64
    build_type=Debug
    compiler=gcc
    compiler.libcxx=libstdc++
    compiler.version=7
    os=Linux

I think it might be related to this issue from devtoolset-7: https://bugzilla.redhat.com/show_bug.cgi?id=1546704

Basically, on RHEL or CentOS before version 8, the cxx11 ABI is never used, despite any settings.

Interestingly enough, only some of the libraries I have used so far have abi:cxx11 in them:

[datalogics-kam]

Any insights appreciated. For now, we're going to force local builds and see if that helps.

[SSE4]

@datalogics-kam we have to rebuild libraries I believe, I'll trigger rebuild and let you know

[solvingj]

@SSE4 do we know if the rebuild fixed this?

[SSE4]

@solvingj unfortunately, no, seems to be a different problem (the one with rebuild was about 1.66.0 branch). sorry for the inconveniences.
