Using Ubuntu 12.10 have been using python 2.7 and python 3.2 successfully. 2.7 is my default interpreter.

Now, after installing python 3.3 it looks like the python3.3 version of "/usr/include/python3.3" was not installed (as it is for "usr/include/python3.2" .

I have already done "sudo apt-get install python-dev" .

I discovered this after trying to build a python library and got a Python.h missing error.

Any idea what I'm doing wrong ?

Thanks

Thank you very much. That solved my problem.
