Unable to load GDAL support, no heightmap export possible #229

Open PeteMichaud opened 8 years ago

PeteMichaud commented 8 years ago

I'm on the latest OSX, and I have GDAL installed from the recommended: http://www.kyngchaos.com/software:frameworks (version 1.11 of GDAL apparently. I understand 2.x versions have a problem with imports too).

In the python shell I run from osgeo import gdal and it works fine, importing without an issue.

When I run worldengine with options, I get the full output, but near the top of that output is "Unable to load GDAL support, no heightmap export possible" - I want that heightmap!!

Am I doing something wrong?

Have a look here: https://github.com/Mindwerks/worldengine/blob/master/worldengine/imex/__init__.py

We try importing just like you do, in case that fails we try just importing gdal directly.

Then we give up. For whatever reason, WE can't find your libs. The question becomes is, your "python shell" is aware of your libraries but is your normal shell or however you are running WE?

Yeah, I don't know -- I also saw that bit of code which is why I tried it in the shell. I'm not really a python dev, so I'm not sure how the loading works.

I just ran python from my terminal, and did the import, successfully. Then I exited python, and ran worldengine from the same directory I ran python--that's when I got the error.

I'm assuming python runs under my user, and that worldengine does also, so I would also assume that even if only my user had gdal in its $PATH that both would have worked.

I don't know how to troubleshoot this more. Is there some way to make sure worldengine has a certain path?
