Re: Changing python-wrapper to handle lib/ etc.

[Andreas Enge]

The first problem occurs. Swig does not compile any more:
   http://hydra.gnu.org/build/134889/log/raw

There are lots of error messages of the form:
checking testcase namespace_nested under python
namespace_enum_wrap.cxx:154:21: fatal error: Python.h: No such file or directory
 # include <Python.h>

If one compares with the version in master:
   http://hydra.gnu.org/build/131472/log/raw
one realises that there python was simply not found, so the tests were
probably not executed:
checking for Python header files... 
checking for Python library... Not found
checking for python3... no

With the new python wrapper, something is found:
checking for python3-config... python3-config
checking for Python 3.x prefix... 
/gnu/store/r6614z0w2inxn78wzaa7ic5sai8s7l9f-python-3.3.5
checking for Python 3.x exec-prefix... 
/gnu/store/r6614z0w2inxn78wzaa7ic5sai8s7l9f-python-3.3.5
checking for Python 3.x version... python3.3
checking for Python 3.x lib dir... lib
checking for Python 3.x header files... 
-I/gnu/store/r6614z0w2inxn78wzaa7ic5sai8s7l9f-python-3.3.5/include/python3.3m 
-I/gnu/store/r6614z0w2inxn78wzaa7ic5sai8s7l9f-python-3.3.5/include/python3.3m
checking for Python 3.x library... Not found

Whatever this means! The header files are correctly located in the python3.3m
subdirectory of the include directory. However, the CPATH includes only
the include/ directory itself (logic!). And apparently the tests do not
use the correct include path.

Could maybe a swig specialist have a look?
