qgis-22: Build Fails, Translations?

[dakcarto]

Hi. This is the appropriate place to report issues.

Since your Mac is probably compiling using multiple cores, the text directly before the make error may be unrelated (since it can be from a different thread). Please follow the Troubleshooting Homebrew guide.

Specifically, do the following:

brew gist-logs --config --doctor qgis-22

Post a link to the generated gist here. Be sure to post the https: link from the browser bar and not the git: link.

Note: the brew tap --repair warnings are described in the tap's README.md

Thanks for your helpful tips and patience!

Here's the gist logs: https://gist.github.com/anonymous/10306820

As I mentioned, I unlinked a mostly-working qgis-20 just before this install attempt. The survex and wxmac Doctor warnings are from an attempt at porting some unrelated cave survey software.

The actual error is with PyQt4:

Traceback (most recent call last):
  File "/usr/local/Cellar/pyqt/4.10.4/lib/python2.7/site-packages/PyQt4/uic/pyuic.py", line 31, in <module>
    from PyQt4 import QtCore
ImportError: No module named PyQt4
make[2]: *** [python/plugins/fTools/tools/ui_frmEliminate.py] Error 1
make[1]: *** [python/plugins/fTools/tools/CMakeFiles/fTools-tools.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....

This is odd since PyQt4 was found OK during CMake configure. Do you have a different PyQt4 installed in the system Python site-packages (shouldn't matter, though)?

Try setting PYTHONPATH, prior to brew install qgis-22 ...:

 export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

This assumes Homebrew pyqt is installed and /usr/local/lib/python2.7/site-packages/ contains PyQt modules. Did you install pyqt for Python 3.x instead of Python 2.x? This would explain why the formula thinks it is installed, but then can't find it (though configure should fail then). QGIS only supports Python 2.7.

I have only the 2.7 version of PyQT installed, from the Homebrew pyqt package which I see has the following note in its info message:

[driggs@davids-mbp ~]$ brew info pyqt
pyqt: stable 4.10.4
http://www.riverbankcomputing.co.uk/software/pyqt
/usr/local/Cellar/pyqt/4.10.3 (560 files, 17M)

==> Caveats
Phonon support is broken.
If you need Python to find the installed site-packages:
  mkdir -p ~/Library/Python/2.7/lib/python/site-packages
  echo '/usr/local/lib/python2.7/site-packages' > ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth

I did not make the above change to 'homebrew.pth' (which doesn't exist).

However, I do note that I have no PYTHONPATH set at all (for fear of messing with virtualenvs). So I set export PYTHONPATH=/usr/local/lib/python2.7/site-packages then attempted a build again... and now I have a working qgis-22!

On startup, I see the following warning on the console:

Warning: loading of qt translation failed [/usr/local/Cellar/qt/4.8.5/translations/qt_en_US]

But so far 2.2 appears to be working properly! Thanks!

[dakcarto]

Thanks for the good reports, and glad you got it working.

I was not aware of the 'homebrew.pth' setup. That seems to be a caveat when Homebrew notices you built pyqt against the system Python, instead of Homebrew's. The 'homebrew.pth' setup allows for a fixed solution compared to setting PYTHONPATH.

Did you install pyqt before installing Homebrew's python? This would explain some stuff. If so, I recommend:

brew rm pyqt && brew install pyqt
# brew reinstall pyqt <-- should work, but not entirely sure it won't use the system Python again

The Warning: loading of qt translation failed... is just the fact that QGIS.app doesn't have a qt_en_US translation, as that is already the default. It's a Mac-only bug that needs fixed, and is harmless.

@riggsd Btw, I do quite a bit of cave exploration in Jewel Cave, in SD, and Lechuguilla, in NM.
