POOverride setup.cfg options to achieve default behavior

copied!<p>I have a setup.cfg containing Linux installation options,</p> <pre><code>[install] prefix=/opt/foo install-lib=/opt/foo </code></pre> <p>which corresponds to the default directory layout this project has under Linux.</p> <p>Now the same project uses py2exe for Windows installation. Currently, I'm using a .bat file to move this setup.cfg out of the way while running <code>python setup.py py2exe</code> in order not to confuse py2exe with those setting, which I think amounts to distutils/py2exe using default parameters.</p> <p>I'd much rather invoke <code>python setup.py py2exe</code> with some extra arguments to override those specified in setup.cfg, but using <code>--prefix= --install-lib=</code> gives me</p> <pre><code>[...] *** copy data files *** Traceback (most recent call last): File "setup.py", line 158, in <module> **platformOptions) File "C:\Python27\lib\distutils\core.py", line 152, in setup dist.run_commands() File "C:\Python27\lib\distutils\dist.py", line 953, in run_commands self.run_command(cmd) File "C:\Python27\lib\distutils\dist.py", line 972, in run_command cmd_obj.run() File "C:\Python27\lib\site-packages\py2exe\build_exe.py", line 243, in run self._run() File "C:\Python27\lib\site-packages\py2exe\build_exe.py", line 312, in _run self.create_binaries(py_files, extensions, dlls) File "C:\Python27\lib\site-packages\py2exe\build_exe.py", line 560, in create_binaries install_data.ensure_finalized() File "C:\Python27\lib\distutils\cmd.py", line 109, in ensure_finalized self.finalize_options() File "C:\Python27\lib\distutils\command\install_data.py", line 41, in finalize_options ('force', 'force'), File "C:\Python27\lib\distutils\cmd.py", line 298, in set_undefined_options src_cmd_obj.ensure_finalized() File "C:\Python27\lib\distutils\cmd.py", line 109, in ensure_finalized self.finalize_options() File "C:\Python27\lib\distutils\command\install.py", line 353, in finalize_options 'userbase', 'usersite') File "C:\Python27\lib\distutils\command\install.py", line 504, in convert_paths setattr(self, attr, convert_path(getattr(self, attr))) File "C:\Python27\lib\distutils\util.py", line 199, in convert_path raise ValueError, "path '%s' cannot be absolute" % pathname ValueError: path '/opt/trelby' cannot be absolute </code></pre> <p>which is the same behavior as when not trying to override setup.cfg parameters at all, so something seems to go wrong.</p> <p>I'm also willing to alternatively set <code>distutils.core.setup()</code>'s <code>options</code> parameter in setup.py, if necessary, but the main question seems to be: to what value, in order to achieve default py2exe behavior?</p> <p>BTW, code is found at <a href="https://github.com/oskusalerma/trelby" rel="nofollow">https://github.com/oskusalerma/trelby</a></p>
