[vtk-developers] dashboard failure with Java wrapping and Obj-C++?

[David Gobbi]

Hi Sean,

The old Rendering/CMakeLists.txt had the following lines, were they
responsible for eliminating the error during the pre-modularization
build?

# Fix for bug#1026 moved out of the common section.  This should be
# changed to add the flag only in the right places (CMAKE_CXX_FLAGS?).
IF(APPLE AND VTK_WRAP_JAVA)
  ADD_DEFINITIONS("-ObjC++")
ENDIF(APPLE AND VTK_WRAP_JAVA)

 - David
