Errors while installing dependencies for pyCGNS

I've a bunch of dependencies that have to be installed before trying to install pyCGNS. So I've probably did something wrong on the road, can someone tell me what ?

Actually the required dependencies are:

Python (starting from v2.4)
numpy (v1.1 +)
cython (v0.16 +)
VTK (v5.8 +)
Qt (v4.7 +)
pySide (for Qt v4.7 +)
hdf5 (v1.8.5 +)

$ python -V
Python 2.7.6

$ python -c 'import numpy;print numpy.version.version'
1.9.2

$ cython --version
Cython version 0.22

$ python -c 'import vtk; print vtk.VTK_VERSION'
5.8.0

$ pkg-config --modversion QtCore
4.8.6

$ python -c 'import PySide; print PySide.__version__'
1.2.2

The CHLone documentation says that I must have the thread-safe feature of HDF5 enabled to be able to install CHLone.

The CHLone requires you have the thread-safe feature of HDF5 enabled. You have setup the HDF5 build with the thread-safe and the enable-pthreads flags in the configure command line...

So I did this to install HDF5:

$ ./configure --prefix=/usr/local/hdf5 --libdir=/usr/local/hdf5/lib --bindir=/usr/local/hdf5/bin --enable-shared --with-pic
$ make
$ make install

CHLone (v0.4 +)

To install CHLone, I used scons like indicated in the documentation:

scons
scons install root=/usr/local

Installing pyCGNS

I've edited the pyCGNSconfig_user.py to indicate hdf5 and CHLone locations:

HDF5_PATH_INCLUDES    = ['/usr/local/hdf5/include']
HDF5_PATH_LIBRARIES   = ['/usr/local/hdf5/lib']
CHLONE_PATH_INCLUDES    = ['/usr/local/include/CHLone']
CHLONE_PATH_LIBRARIES   = ['/usr/local/lib']

Then I used these commandes to install it:

python setup.py build
python setup.py install --prefix=/usr/local

Now when I run tests in the documentation it outputs:

$ python -c 'import CGNS.MAP.test;CGNS.MAP.test.run()'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named CGNS.MAP.test

Which version of pyCGNS do you use?

Did you test a simple import using python -c 'import CGNS.MAP'?

Maybe the CHLone lib is not in your LD_LIBRARY_PATH which makes the import fail.
