[ITK Community] [Insight-users] Version 4.5 and QT issue

[Bradley Lowekamp]

You can utilize otool in inspect libraries and executables:


$ otool -L `which qmake`
/usr/bin/qmake:
	/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices (compatibility version 1.0.0, current version 38.0.0)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 625.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 123.0.0)
	/System/Library/Frameworks/CoreServices.framework/Versions/A/CoreServices (compatibility version 1.0.0, current version 44.0.0)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 550.0.0)
$ qmake -version
QMake version 2.01a
Using Qt version 4.8.5 in /Library/Frameworks

You should/need to use the same standard C++ library a cross your project. Unless you can ensure that you std library c++ symbols intermingle.
