[ITK-dev] Failing link on Mac after May 7 changes

[Bradley Lowekamp]

Bill,

This compiler has known problems with visibility. These are the lines that should disable it for your compiler:
https://github.com/InsightSoftwareConsortium/ITK/blob/master/CMake/ITKModuleMacros.cmake#L12-L15

What is the value of USE_COMPILER_HIDDEN_VISIBILITY in you CMakeCache.txt files? Does manually setting it to off resolve your issue?

Brad
