I've a very strange problem while trying to compile a the example provided at
http://www.cmake.org/Wiki/images/2/25/QtTest-Package-Example.zip System Informations: Mac OSX 10.5.8 cmake version 2.8.7 installed from latest dmg package available Qt 4.8.1 Installed from latest repositories I issue the following commands in the QtTest-Package example cmake . make I kept the original CMakeLists.txt unmodified but at last stage, the linker can't find symbols and this is the output: ld warning: in /Library/Frameworks//QtGui.framework/QtGui, file is not of required architecture ld warning: in /Library/Frameworks//QtCore.framework/QtCore, file is not of required
