python setup.py develop not transparent to the user about sherpa HOT 3 CLOSED

The issue is that for python setup.py build_ext --inplace, the sherpa_config.build_configure method here is never called, which appends the psf and some other extensions to ext_modules:

            self.distribution.ext_modules.append(build_ext('psf', *build_lib_arrays(self, 'fftw')))
            self.distribution.ext_modules.append(build_ext('wcs', *build_lib_arrays(self, 'wcs')))

Following the advice of @taldcroft at #15 (comment) and #13 (comment) I'll now try to get python setup.py install working in a Conda environment for Sherpa development.

But it would be nice if in the future someone could make python setup.py build_ext --inplace and thus python setup.py develop work.

You need to add the sherpa_config command in order to have all of the extensions built.

This seems to work for me:
python setup.py sherpa_config build_ext --inplace

After that, I can also python setup.py develop, although the stack extension does not get installed automatically.

I will take this ticket as a request to make python setup.py develop work transparently, which will include making sure that the external python extensions are correctly installed.

@olaurino – I just now tried again, and now installing Sherpa and sherpa_test work for me with my normal Python environment (Macports), which is convenient for me. Thank you!
