I'm trying to fix a problem with the python
wrapper of my library. In my CMakeLists.txt
there are the following lines:<br>
</div>
<div><br>
</div>
<div>find_package(VTK REQUIRED COMPONENTS
vtkFiltersSources vtkIOLegacy
vtkFiltersExtraction vtkFiltersGeometry
vtkFiltersModeling vtkRenderingFreeType
NO_MODULE)<br>
<br>
include(${VTK_USE_FILE})<br>
</div>
<div><br>
if(VTK_WRAP_PYTHON)<br>
find_package(PythonLibs 2.7 REQUIRED)<br>
<br>
if(PYTHONLIBS_FOUND)<br>
<br>
include_directories(${PYTHON_I<wbr>NCLUDE_DIRS}
${PROJECT_SOURCE_DIR})<br>
<br>
include(vtkWrapPython)<br>
<br>
vtk_wrap_python3(${PROJECT_NAM<wbr>E}Python
${PROJECT_NAME}Python_srcs
vtkPolyDataBooleanFilter.cxx)<br>
<br>
add_library(${PROJECT_NAME}Pyt<wbr>honD
${${PROJECT_NAME}Python_srcs})<br>
target_link_libraries(${PROJEC<wbr>T_NAME}PythonD
${PROJECT_NAME})<br>
<br>
add_library(${PROJECT_NAME}Pyt<wbr>hon
MODULE ${PROJECT_NAME}PythonInit.cxx)<br>
target_link_libraries(${PROJEC<wbr>T_NAME}Python
${PROJECT_NAME}PythonD)<br>
<br>
endif()<br>
endif()<br>
<br>
</div>
When I try to import the module into a python
script, I get an import error about undefined
symbols like PyVTKObject_Type. After a little
research with nm I found out that the shared
object is not linked to
libvtkWrappingPython27Core. Here are the first
lines of it:<br>
<br>
</div>
U PyBool_FromLong<br>
U PyDict_SetItemString<br>
U PyErr_Occurred<br>
U PyInt_FromLong<br>
U PyModule_GetDict<br>
U PyString_FromString<br>
0000000000003020 T PyVTKAddFile_vtkPolyDataBoolea<wbr>nFilter<br>
U PyVTKClass_New<br>
U PyVTKClass_Type<br>
U PyVTKClass_vtkPolyDataAlgorith<wbr>mNew<br>
<br>
</div>
How to fix this? There is no documentation about
the the python wrapper, except <a href="https://www.vtk.org/Wiki/VTK/Python_Wrapping_FAQ" target="_blank">https://www.vtk.org/Wiki/VTK/P<wbr>ython_Wrapping_FAQ</a>.<br>
<br>
</div>
I'm actually using VTK 6.3 and my library can be
found on <a href="https://github.com/zippy84/vtkbool" target="_blank">https://github.com/zippy84/vtk<wbr>bool</a>.<br>
