Bug 353821

The problem is that your list of search paths is broken; I don't know why, the code which creates that didn't change as far as I can see. What is your sys.path if you print it from python?

assuming you built this yourself: is the PYTHON_EXECUTABLE define in build/kdevpythonversion.h correct?

~/dev/kdev-python$ grep PYTHON_EXECUTABLE build/kdevpythonversion.h
#define PYTHON_EXECUTABLE ""

That probably explains it. I've run cmake with :
  cmake -DPYTHON_EXEC=~/.pyenv/versions/3.4.3/bin/python ../

Was anything else required?

P.S. My sys.path looks OK - this is printed from kdevelop shell:

$ python

Ah, then that is probably the reason ... I don't know how FindPython.cmake works exactly, but apparently that makes it fail to find the correct path. I suggest you just run ccmake and enter the path there. Let me know if it works after that.

OK, that fixed it.

As a suggestion - if PYTHON_EXECUTABLE is empty, may be kdev-python should
search for one in the PATH? - this will make it very convenient to use with
python virtualenv.

BTW, Where should I open ticket for FindPython.cmake?

I think I will just add a check so it doesn't even compile. You need python as a dependency anyways, when that is empty then something went wrong.

Not sure about FindPython.cmake, I think we borrowed it a while back and it's now in our repo ... I will investigate if we can maybe use the upstream version now, I don't even recall why we copied it back then.

I'll close this, it was a setup issue it seems.
