Tests linking fails with multiple undefined symbols

[barracuda156]

I get this failure at linking (tried gcc12 and gcc11, same result):

What do I miss? gtest and OpenBLAS are installed and work fine otherwise.

Okay, this is needed to fix it: -D_GLIBCXX_USE_CXX11_ABI=0

Hi @barracuda156

Thanks for your interest in my ttv implementation. The library tests only run on Linux (Ubuntu) systems.

[barracuda156]

@bassoy Thank you for responding. I think it should work on any Unix too, there is nothing Linux-specific.

The flag I mentioned is a standard one, Macports passes it quite often. May be worth adding it to CMake lists compile definitions, conditional on Apple.
