Re: [wxVTK] wxVTK: linking problems

[Andrea d. P. R. O. <asd...@gm...>]

Hello Mathieu,

Thanks for your quick reply ;)

I'm using the CMakeLists.txt file that comes in wxVTK-1.2.tgz

Some lines related to the wxWidgets library are:

...
# The following allows you to access wxGLCanvas for GTK
IF(WIN32)
  SET(GUI_EXECUTABLE WIN32)
ELSE(WIN32)
  IF(APPLE)
    SET(GUI_EXECUTABLE MACOSX_BUNDLE)
    IF(VTK_USE_COCOA)
      SET_SOURCE_FILES_PROPERTIES(
        src/wxVTKRenderWindowInteractor.cxx
        PROPERTIES COMPILE_FLAGS "-ObjC++")
    ENDIF(VTK_USE_COCOA)
  ELSE(APPLE)
    # Ok X11 for sure, but just check:
    IF(NOT VTK_USE_X)
      MESSAGE(FATAL_ERROR "You need to have VTK_USE_X")
    ENDIF(NOT VTK_USE_X)
    #FIND_PACKAGE(GTK REQUIRED)
    #INCLUDE_DIRECTORIES(${GTK_INCLUDE_DIR} )
    # CMake 2.4.6:
    FIND_PACKAGE(PkgConfig REQUIRED)
    pkg_check_modules (GTK2 gtk+-2.0)
    # For GTK we need a couple of stuff:
    # gl: GLCanvas
    # adv: wxSashLayoutWindow and such...
    SET( wxWidgets_USE_LIBS gl adv )
  ENDIF(APPLE)
ENDIF(WIN32)

# wxWidgets is required to build the project
FIND_PACKAGE(wxWidgets REQUIRED)

IF(wxWidgets_FOUND)
  INCLUDE( ${wxWidgets_USE_FILE} )

  #Add our own include path
  INCLUDE_DIRECTORIES(
    ${wxVTKSample_SOURCE_DIR}/src
    ${GTK2_INCLUDE_DIRS}
    )

... here some lines related to the projects, and:

LINK_LIBRARIES(
  vtkRendering
  ${wxWidgets_LIBRARIES}
  ${GTK2_LIBRARIES}
  )
IF( "${VTK_MAJOR_VERSION}" STREQUAL "5")
  LINK_LIBRARIES( vtkWidgets )
ENDIF( "${VTK_MAJOR_VERSION}" STREQUAL "5")

... some ADD_EXECUTABLE sentences, and ends with:

ELSE(wxWidgets_FOUND)

  MESSAGE("Cannot find wxWidgets libraries and/or header files")

ENDIF(wxWidgets_FOUND)

That's all. (I attach to this mail the whole CMakeLists.txt file)

I don't know if the sentence IF( "${VTK_MAJOR_VERSION}" STREQUAL "5")
could be the problem, because I'm not using VTK 5.0...

Thanks for your help,

Andrea Rueda
