[ITK Community] Linker errors on Mac 10.7 with ITK 4.5.1

[Fetzer, Andreas]

Hi Brad,

I finally got it working. I had to disable BUILD_TESTING and BUILD_EXAMPLES in CMake.

I will try to set up a dartclient this week. Is there a way in the dashboard script to force the build as shared libraries?

Thanks a lot again!

Andreas

Hello,

I was unable to reproduce your error on the current release branch.

$ clang --version
Apple clang version 3.1 (tags/Apple/clang-318.0.54) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin11.4.2
Thread model: posix

$ CC=/usr/bin/clang CXX=/usr/bin/clang++ cmake DBUILD_SHARED_LIBS:BOOL=ON ../ITK && make -j 6

This compiled fine for me.

Brad

Hi Matt,

yes I have seen that the patch was merge into your release branch. However I still get linker errors. This time for itk::NumericTraits:

Linking CXX executable ../../../../bin/ITKCommon1TestDriver

Is this already know to you?

No.  If this platform is important to you, please consider setting up a Nightly dashboard submission [1].  Inspecting the code, I do not see the issue.  The symbol appears to be created [2] with the correct exports [3].  Maybe a dashboard submission will show details that will help us work together to fix the issue.

When will the 4.5.2 be released?
Our own release is scheduled for the end of March. Before that we would like to solve the linker errors in ITK.


If we can get issue fixed, we would be happy to coordinate with you and get 4.5.2 released in later in March before your release.

Thanks,
Matt
