#204 pymol install doesn't compile python scripts in modules

[Jack Howarth]

The current pymol sources don't appear to compile the python scripts in the modules directory (at least as we are installing them under MacPorts https://github.com/macports/macports-ports/blob/master/science/pymol/Portfile ). Oddly all the python scropts outside of the modules subdirectory are properly compiled. Any idea why this is happening?

[Jack Howarth]

FYI, the current 2.1.0 release with PyQt support can be built under MacPorts with the proposed packaging changes at https://trac.macports.org/ticket/56139 .

[Jack Howarth]

The actual problem stems from setup.py not installing the modules directory. Is there a reason why we have to manually install that directory?

[Thomas Holder]

what do you mean by it's not installed? What's your manual step?

[Jack Howarth]

This is using the MacPorts python packaging for the 2.7 and 3.x series using the Python port group for installing python packages.

https://guide.macports.org/chunked/reference.portgroup.html

which should be installing pymol with....

${python.bin} setup.py install --no-user-cfg --prefix=${python.prefix} --root=${destroot}

Note that the fink packaging system sees the same issue...

https://github.com/fink/fink-distributions/blob/master/10.9-libcxx/stable/main/finkinfo/sci/pymol-py.info

and the modules subdirectory has to be explicitly copied over there as well. So it seems that the install method in setup.py doesn't consider the modules subdirectory.

[Jack Howarth]

Does the incentive build install the modules subdirectory? I don't recall it having APBS Tools plugin. Perhaps it has been omitted by accident because of that.

[Jack Howarth]

The problem is in the fink and macports packaging which was based on a much earlier behavior of PYMOL_PATH. Setting it to

PYMOL_PATH=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pymol/pymol_path

instead of

PYMOL_PATH=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pymol

eliminated the need for the redundant installation of the subdirectories associated with pymol_path.

[Thomas Holder]

is this issue resolved for you? It works fine in my hands, doing "/opt/local/bin/python setup.py --no-user-cfg install --prefix=... --root=..." installs everything.
