How can I compile xtensor with gcc-7.5 #2778

Closed guoxxiong closed 6 months ago

guoxxiong commented 7 months ago

I am keeping the default gcc-7.5 on ubuntu 18.04. No upgrade gcc, anyone have ideas to compile successfully. Thanks

Could you please list the error?

guoxxiong commented 7 months ago

error like this: xtensor/xexpression.hpp:172:9: internal compiler error: Segmentation fault

The same issue "2289" can be solved by upgrading gcc and g++ to 8.4. I wonder if it is possible to compile without upgrading gcc.

Hi,

We've dropped support for gcc-7 as it is really outdated now. If you can't upgrade your system compiler, you can install micromamba, cd to xtensor, and then tun the following:

micromamba env create -f environment-dev.yml
micromamba activate xtensor
micromamba install compilers

And then you can pass the following variables to cmake: -DCMAKE_C_COMPILER=$CC -DCMAKE_CXX_COMPILER=$CXX. This way it should use the compiler in your micromamba environment instead of your system compiler.

Closing as we don't support gcc 7 anymore, the only solution is to upgrade the compiler (either the systme one, or using micromamba).
