Sounds like a bug in waf: I have to call waf with python3, else it assumes that the python binary to use is the one running waf, instead of using the PYTHON environment variable. I'm not even sure using the PYTHON environment variable would be the recommended way to fix this... I use a shell function to change /usr/bin/python to link to python2.6 or python3 as required, and it works for me. Or you can call waf as $ python3 ./waf configure Which is the solution you have discovered already. Or you can edit ./waf to set the line #!/usr/bin/env python3 What are you trying to do - compile Python 3 code by running Python 2? I don't think that can ever work completely because creating the .pyc and .pyo files requires the correct version of Python. Possibly waf could run under Python 2, and then call Python 3 as required. But it would complicate waf. If you think this is a waf bug, and not a limitation, then mail the waf list, or open a waf bug report. Really, you should at least document this in INSTALL... |
