[pymvpa] Install problem on Scientific Linux

[Loris Bennett]

Hi,

I am have tried versions 0.4.6, 0.4.7 and the git snapshot and getting
the following error when trying to install on Scientific Linux 6.1 with
some package from SL 6.2:

,------------------------------------------------------
| # ./setup.py build
| Traceback (most recent call last):
|   File "./setup.py", line 12, in <module>
|     from numpy.distutils.core import setup, Extension
| ImportError: No module named distutils.core
`------------------------------------------------------

I can fix this with the following patch:

,----------------------------------------------------
| 12c12,13
| < from numpy.distutils.core import setup, Extension
| ---
| > import numpy
| > from distutils.core import setup, Extension
`----------------------------------------------------

I then get the error:

,----------------------------------------------------------------------------------------------
| mvpa2/clfs/libsvmc/svmc_wrap.c:2705:31: error: numpy/arrayobject.h: No such file or directory
`----------------------------------------------------------------------------------------------

which I can fix with this patch:

,---------------------------------------------------
| 21c22
| < libsvmc_include_dirs = []
| ---
| > libsvmc_include_dirs = ['.',numpy.get_include()]
`---------------------------------------------------

The next error is:

,-----------------------------------------------------------------------------------------------------
| mvpa2/clfs/libsvmc/svmc_wrap.c:2718: error: expected specifier-qualifier-list before ‘svm_parameter’
`-----------------------------------------------------------------------------------------------------

which is due to my libsvn not being in an expected place and can be
fixed by adding the appropriate options.  However, I get a further error:

,------------------------------------------------------------------------------------------------

`------------------------------------------------------------------------------------------------

This seems to be because 'gcc' is used to compile, rather than 'g++',
and the file name ends in '.c', so the compiler expects C rather than
C++.  If I copy the last call and replace 'gcc' with 'g++', it compiles.

I assume these difficulties do not normally occur and that my set-up is
somehow broken.  Does anyone have an idea what the problem might be?

Cheers

Loris
