[vtk-developers] cannot link QVTKWidgetPlugin.dylib

[Aaron Knoll]

Thank you Jean-Christophe,

This helped, but now I get a linker error:

[wireless-128-62-222-46:~/work/PanFluExercise-knolla/build] knolla% make -j12
Linking CXX executable exercise.app/Contents/MacOS/exercise
ld: can't open file, errno=13 for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

It's not more specific than that, but it's missing something. I still suspect an issue with QVTKWidgetPlugin.

Thanks if you have suggestions,

Aaron

Hi Aaron,

What about using directly the variable VTK_LIBRARIES.

Instead of:

find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
set(LIBS ${LIBS} QVTKWidgetPlugin vtkRenderingFreeTypeOpenGL vtkRenderingVolumeOpenGL vtkInteractionStyle vtkChartsCore )

try:

find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
list(APPEND LIBS ${VTK_LIBRARIES})

I'm compiling a project that depends on QVTKWidgetPlugin. In CMakeLists I have the following:

find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
set(LIBS ${LIBS} QVTKWidgetPlugin vtkRenderingFreeTypeOpenGL vtkRenderingVolumeOpenGL vtkInteractionStyle vtkChartsCore )

ld: library not found for -lQVTKWidgetPlugin
clang: error: linker command failed with exit code 1 (use -v to see invocation)

The only difference I've noticed is in VTK/lib, all other libraries have version numbering, e.g.

libvtkzlib-6.0.1.dylib
libvtkzlib-6.0.dylib

And QVTKWidgetPlugin does not:

libQVTKWidgetPlugin.dylib

But even when I manually create symbolic links, linking fails with exactly the same error!

Any ideas? Thanks!

-Aaron
