Bug 193900 – sci-libs/vtk-5.0.3 does not declare /usr/lib/python2.4/site-packages/vtk/ in the LDPATH

• Product: Gentoo Linux
• Status: RESOLVED FIXED

While building salome (www.salome-platform.org), the system complains that it cannot find libvtkCommonPython

(cd . && ln -s SALOME_GenericObjSK.lo SALOME_GenericObjSK.o)

It turns out that the /etc/env.d/40vtk does not add /usr/lib/python2.4/site-packages/vtk/ to the LDPATH.

Markus, can you fix that?

Daniel

Reproducible: Always

Markus,

I went a little bit further with that.
Salome-GUI was clearly specifying -L/usr/lib/vtk-5.0/python where the libraries were in /usr/lib/python2.4/site-packages/vtk.
Once I replaced the path in the right file in salome, things went right. So I removed the LDPATH=/usr/lib/python2.4/site-packages/vtk I had put in /etc/env.d/40vtk.

Two questions though:
- Why did the system never found the libraries? They should have been available anyway, whatever the -L/blabla, isn't it?
- Is there anything that should be corrected in the vtk ebuild to avoid such situations?

Markus,

What about that question?

Hi Daniel,

Thanks for the reminder and happy New Year!
From what you posted it seems to me that this
is something that should be addressed by Salome
not VTK. All python related libraries should ideally
end up in /usr/lib/python2.x/site-packages and that's
where packages should look for them.

Does Solome have a switch for this?
Simply assuming that the libraries are in 
/usr/lib/vtk-5.0/python seems fairly random.

cheers,
Markus

Hi Daniel,

Where are we with this issue. Still a problem?

Thanks,
Markus
