py27-spatialite does not build and install

[danrabin]

On a clean, freshly installed Macports, sudo port install py27-spatialite fails with

:info:build __main__.HeaderNotFoundException: cannot find proj_api.h, bailing out

Dependency is on proj4, which doesn't seem to install the file in question, but not clear whether proj4 or py27-spatialite is at fault.

I've run into this bug too (and now QGIS has stopped working!)

The comment

may be incorrect. At least on my system, proj4 does install /opt/local//lib/proj49/include/proj_api.h. From this I think the fault is not proj4 but in py27-spatialite.

Hi I've checked. py27-spatialite does not see the new "proj49" (proj 4.9.3) or "proj5" (proj 5.0.0) folder inside /opt/local/lib/ and it does not see all bin and lib inside. It's important to remember that proj 5.0.0 has bug and now it's better the 4.9.3 version. The error is inside py27-spatialite.

py27-spatialite error is important because it stop QGIS and QGIS3

I've created some symbolic links inside /opt/local/bin and lib folder: py-spatialite see these binaries and it is built without errors.

This is not the best solution but it works:

$ sudo ln -s /opt/local/lib/proj49/bin/geod /opt/local/bin/
$ sudo ln -s /opt/local/lib/proj49/bin/nad2bin /opt/local/bin/
$ sudo ln -s /opt/local/lib/proj49/bin/proj /opt/local/bin/
$ sudo ln -s /opt/local/lib/proj49/lib/libproj.dylib /opt/local/lib/
$ sudo ln -s /opt/local/lib/proj49/lib/libproj.a /opt/local/lib/
$ 
$ sudo port upgrade py-spatialite

Unfortunately this hack does not work for me.

sudo port upgrade py-spatialite

Above links worked for me ;-)

The install paths for proj (version 5) and proj4 have been modified to allow for parallel installation without conflict. Using symbolic links as described here subverts the intent of these modifications and should be removed once a better fix is committed.

The correct fix is to patch setup.py to use the new install paths. See #56150 for a more detailed discussion of the issue.
