Installing numpy on an "unsupported" platform
Hello, I am using Python 3.10.0 on OpenIndiana and yesterday I tried to install numpy in my system. The command /opt/gnu/python/bin/python3.10 -m pip install --user numpy failed and it it printed a long error report. The errors are of the form from numpy/core/src/umath/string_ufuncs.cpp:1: /usr/gcc/10/include/c++/10.4.0/cmath:1134:11: error: 'llrint' has not been declared in '::' 1134 | using ::llrint; | ^~~~~~ First I have noticed that '<command-line>: warning: "__STDC_VERSION__" redefined' and after some experimentation I realized that the extra option -D__STDC_VERSION__=0 is actually the one that causes the problem. So my question is: How can I disable this option? Regards, Apostolos

That seems wrong indeed. It's set on line 260 of the main `setup.py` file for numpy. We require C99, so you can try setting it to 199901L. I suspect that that will fix it since `llrint` is a C99 function. If that does work, please let us know so we can fix things up. And if it doesn't work, please open an issue at https://github.com/numpy/numpy/issues/ and Cc me (@rgommers); the issue tracker is a better place than the mailing list to work through build problems. Cheers, Ralf
