[vtk-developers] vtk_netcdf

[Christopher Knox]

Thanks I figured that this was a problem well within cmake's  
capabilities.

I do know know which of the netcdf files requires the -fno-common  
flag - so I just applied it to all the netcdf files. Adding the  
following to the CMakeLists.txt file in the vtknetcdf directory  
solved the problem.

IF(APPLE)
   SET_SOURCE_FILES_PROPERTIES(
     ${netcdf_SRCS}
     PROPERTIES COMPILE_FLAGS -fno-common)
ENDIF(APPLE)

Cheers,
Chris

PS I don't know if the was the 'right' place to modify the CMakeLists  
files.
