New submission from Paul Menzel <pmenzel+bugs.python....@molgen.mpg.de>:
[copied from closed (out of date) issue https://bugs.python.org/issue25946] Reproduced with Python 3.9.6. ./configure` both prints `checking for g++... no` and WARNING: By default, distutils will build C++ extension modules with "g++". If this is not intended, then set CXX on the configure command line. if `/usr/bin/g++` is present and executable which doesn't seem to be constructive because it's quite common that one wants to use `/usr/bin/g++` as CXX compiler if available. In case incompatibilities exists with other C++ compilers there should a check and more detailed error message. Furthermore the error message doesn't explain if a part of distutils won't be build because the message sounds like the C++ extension is built, but does it work without a C++ compiler? Specifying `CXX` environment variable or `--with-cxx-main=/usr/bin/g++` `configure` option works fine. ---------- components: Build messages: 399497 nosy: iritkatriel, krichter, pmenzel priority: normal severity: normal status: open title: configure should pick /usr/bin/g++ automatically if present versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44909> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
