mesh extraction setup error: x86_64-conda-linux-gnu-c++: error: unrecognized command-line option '-march'

Thanks for your guidelines! I followed the provided instructions and also copied the files as @rfeinman has mentioned before in #2 , but I met a problem: x86_64-conda-linux-gnu-c++: error: unrecognized command-line option '-march' It seems that the c++ version is not suitable, how can I fix this bug?

Thanks for your help!

Hi @wenqsun could you maybe share your operating system and hardware details, as well as the output from conda list? Thanks!

The CUDA Driver Version is 12.1, the OS is Ubuntu 20.04 LTS, and the versions for my related package installation are listed below as a reference:

If you need more information, please let me know. Thank you!

It seems that gxx_linux-64 is not listed in your specifications? In that case could you try install the conda envinoments using conda env update -f environment.yml?

Could you also dump the output of which x86_64-conda-linux-gnu-c++? and x86_64-conda-linux-gnu-c++ --version?

[wenqsun]

Sorry that I forget to provide the information about gxx_linux-64. I have installed the gxx_linux-64

Also, the output of which x86_64-conda-linux-gnu-c++ is my_path/envs/xcube/bin/x86_64-conda-linux-gnu-c++, and the version output is x86_64-conda-linux-gnu-c++ (conda-forge gcc 11.4.0-13) 11.4.0.

I see this is really weird... I originally thought you might be running a wrong version of g++ under a wrong conda environment. But now it seems that everything should be correct.

Then I don't know the reason because I could not reproduce this from my side. Perhaps other can help?

[wenqsun]

OK. Thanks for your help! I will reinstall the environment and try to find out the problems.
