vtk is too picky on libdouble-conversion version #83

Closed alexdesiqueira closed 5 years ago

alexdesiqueira commented 5 years ago

Hey everyone, vtk is very specific on the version of libdouble-conversion:

In [2]: from vtkPVServerImplementationCorePython import *                                      
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-2-fc517bac943d> in <module>
----> 1 from vtkPVServerImplementationCorePython import *

ImportError: libdouble-conversion.so.3.0.0: cannot open shared object file: No such file or directory

Debian stable has version 2.0.1-4; Debian testing/sid, on the other hand, has 3.1.0-3. I tried with both versions, and had the same error. Is it just me, or it should be libdouble-conversion higher than 3.0?

Thanks for all your help y'all.

I am not sure why VTK is trying to dynamically link to a system double-conversion. It appears that VTK bundles its own internal version of the library in the folder ThirdParty/doubleconversion, and that gets built under the library name libvtkdoubleconversion-8.2.so. Given that this is the case, I'm not sure why it is looking for an external system double-conversion library. Does this file exist on your system? (it would be in the /lib subfolder of your anaconda environment).

It looks like conda-forge has its own double-conversion feedstock, so we can probably add that as a dependency and then add -DVTK_USE_SYSTEM_DOUBLECONVERSION:Bool=ON to the CMake flags. I'm not sure why the current configuration is not working, though.

On second look, is vtkPVServerImplementationCorePython part of the VTK package? I get a ModuleNotFoundError if I try to import it. I think that may be part of ParaView rather than VTK proper.

If so, it is probably best to move the issue to the paraview feedstock. Taking a quick look there, it seems that feedstock has not yet been updated for the new compilers and probably needs some work. I am guessing it is just generally incompatible with recent VTK builds.

Hey Greg,

I checked, and this module is part of vtk actually. I used the following code (got the idea here [1]):

import pkgutil
import paraview
import vtk

pack_paraview = paraview
pack_vtk = vtk

for importer, modname, ispkg in pkgutil.iter_modules(pack_paraview.__path__):
    if 'ServerImplementation' in modname:
        print('Found submodule %s in paraview (is a package: %s)' % (modname, ispkg)) 

for importer, modname, ispkg in pkgutil.iter_modules(pack_vtk.__path__):
    if 'ServerImplementation' in modname:
        print('Found submodule %s in vtk (is a package: %s)' % (modname, ispkg))

However, I get the same ModuleNotFoundError when trying to import it.

Yeah, I have this file at /lib.
