But later Matt McCormick replied with a patch that essentially changes __GCCXML__ to CABLE_CONFIGURATION which is defined during the build. That change seems to imply that the workaround is still required.

That may get your build going. OK. So I'm well out of my depth with SSE, but: since the build is targeting i386, I think there would not be SSE support. Another data point is that the cmake configuration step outputs: -- Performing Test VXL_HAS_SSE2_HARDWARE_SUPPORT -- Performing Try-Run Test VXL_HAS_SSE2_HARDWARE_SUPPORT - Test Compilation Failed -- Performing Test VXL_SSE2_HARDWARE_SUPPORT_POSSIBLE -- Performing Test VXL_SSE2_HARDWARE_SUPPORT_POSSIBLE - Success ... and ... -- Performing Test ITK_COMPILER_SUPPORTS_SSE2_64 -- Performing Test ITK_COMPILER_SUPPORTS_SSE2_64 - Failed -- Performing Test ITK_COMPILER_SUPPORTS_SSE2_32 -- Performing Test ITK_COMPILER_SUPPORTS_SSE2_32 - Failed -- Performing Test ITK_COMPILER_DOES_NOT_NEED_MSSE2_FLAG -- Performing Test ITK_COMPILER_DOES_NOT_NEED_MSSE2_FLAG - Failed I'll take a closer look at these tonight. -Steve
