Build error when compiling the extension for Linux platform

[ghost]

I am trying to compile the extension using gcc in Ubuntu. But the compilation fails for this command given in your build instructions. I am using python 3.8.10.

$ python ../../../python/setup.py build_ext --inplace -v

I see a warning but no error in the logs you have shared. What's the issue? What's your gcc version?

The warning happens at build time but it succeed. Then the link command is executed but you're not showing the result of the second command. For me everything is OK and the extension is correctly generated unless you're not showing the complete logs
