Installing python - Missing CMakeList.txt

[acm-234]

I was able to install s2gemoetry, however, when I tried importing it into python I received a module not found error. When I went to the python directory s2geometry/build/python it appears there is no CMakeList.txt file to do a install of the python library. I have swig installed, any recommendations? I apologize if I missed something obvious.

There's src/python/CMakeLists.txt.

I'm guessing either SWIG or Python wasn't found when configuring. https://github.com/google/s2geometry/blob/master/CMakeLists.txt#L534

Look at the entire output of cmake, or paste it here for help debugging.

Interesting. I reran the cmake and make commends and below are the output that seem relevant to SWIG. It looks like it found a version of swig (2) but maybe gave some warnings. I have swig 3 installed as well, is there a way in cmake I can specify swig 3/ could that be the issue? Thanks for helping me out!

It looks like it's building pywraps2 fine. Probably python just isn't finding it.

Do make install and show that output to see where it goes.

Since there was a lot of output I just pasted what. Thought might be relevant. Let me know if you need something else from the output.

When you run python, is it python2 or python3?

[acm-234]

When I run python it uses version 2.7.5. The path to the python function. $which python -> /usr/bin/python

[figroc]

Run python -m site and check that /usr/local/lib64/python2.7/site-packages/ is in the sys.path.

Maybe it's related to #93.

[jmr]

Could you try with #128?

[jmr]

#128 has been merged, you can try at HEAD.
