[Insight-developers] Stripping Libraries on OSX

[Bradley Lowekamp]

Thank you.

The build-time flag I was referring to was actually a linker option[1]:
-s
   Remove all symbol table and relocation information from the executable. 

When this option is passed to the ld linker in OSX the following warning occurs:
ld: warning: option -s is obsolete and being ignored


CMake does not natively support the packaging requirements for different languages. So I have not been able to use the install/strip targets generated by CMake or packaging you linked too.

Currently, I have a manual "dist" target for several languages to perform packaging[2], and not using the cpack infrastructure. I never heard any suggestions or examples on how to utilize cpack and cmake installation to help running a Python "setup.py" for packaging. For Java and CShap simple zips are generated, it wouldn't surprise me if cpack's components could be used for that. It may well worth the time to revisit these packaging issues.

Is there a macro/function to manually run the stripping in cmake? or does it only automatically happen on installation/packaging?

Brad
