[Paraview] 3.12.0-RC3: could not open source file "GL/gl.h" compiling vtkIceTSynchronizedRenderers.cxx

[Takuya OSHIMA]

Hi,

I tried to build the 3.12.0 RC3 with MesaLib-7.11 (OSMesa) on a RHEL
5.1 headless cluster and got an error:

/nfs/work2/v14/v14006/src/ParaView-3.12.0-RC3/VTK/Rendering/vtkOpenGL.h(26): catastrophic error: could not open source file "GL/gl.h"
  # include <GL/gl.h> // Include OpenGL API.
                                            ^

compilation aborted for /nfs/work2/v14/v14006/src/ParaView-3.12.0-RC3/ParaViewCore/ClientServerCore/vtkIceTSynchronizedRenderers.cxx (code 4)
make[2]: *** [ParaViewCore/ClientServerCore/CMakeFiles/vtkPVClientServerCore.dir/vtkIceTSynchronizedRenderers.cxx.o] Error 4

Looking into ParaViewCore/ClientServerCore/CMakeLists.txt I found
nothing that specifies ${OPENGL_INCLUDE_DIR} as opposed to the old
ParaView-3.10.1/Servers/Filters/CMakeLists.txt (where
vtkIceTSynchronizedRenderers.cxx had been in) having

# The following was copy/paste from vtkIncludeDirectories.cmake
# OpenGL include directories.
IF(APPLE)
  IF(VTK_USE_X OR VTK_OPENGL_HAS_OSMESA)
    INCLUDE_DIRECTORIES(${OPENGL_INCLUDE_DIR})
  ENDIF(VTK_USE_X OR VTK_OPENGL_HAS_OSMESA)
ELSE(APPLE)
  INCLUDE_DIRECTORIES(${OPENGL_INCLUDE_DIR})
ENDIF(APPLE)

so perhaps we need something similar around (line 116)

IF (PARAVIEW_USE_ICE_T AND VTK_USE_MPI)
   SET (Kit_SRCS
     ${Kit_SRCS}
     vtkIceTSynchronizedRenderers.cxx)
.....
ENDIF (PARAVIEW_USE_ICE_T AND VTK_USE_MPI)

of ParaViewCore/ClientServerCore/CMakeLists.txt ?
