Summary0008272: CMake 2.6.3 RC5 breaks on Mac OS X
DescriptionThis might be two things

- Makefile and Xcode generator do not honour CMAKE_OSX_ARCHITECTURES, thus setting it to i386 or ppc will always end up

"Undefined symbols for architecture i386:
  "_main", referenced from:
      __start in crt1.o
"
for setting to ppc or vice versa

- similar compiling libraries it seems that twice an architecture is build - lipo complains that both temporary versions are of the same architecture (here i386)




Steps To Reproduce
Additional Information- Mac OS X 10.5.5 on a MBP
- Xcode / Developer Tools with iPhone support v 3.1.2

Did this work with 2.6.2? If the answer is yes, please provide the exact commands that work in 2.6.2 and do not work in 2.6.3.

Thanks.

I just checked - it seems this is more related to some problems in the FindwxWidgets.cmake handling of universal builds (somehow all my current projects relate to wxWidgets). Plain C/C++ programs work fine. It seems that wx-config is pulling in a few compiler settings that are upsetting the way cmake sets up the build. It should be possible to compile/link i386 even if wxWidgets is universal (i386;ppc).

I need to investigate this in more detail. Thus, I would suggest to close this report as non-issue - sorry for the noise.

Found the actual problem: FindwxWidgets copies the -arch flags from wxconfig when creating the Xcode projects. AFAICS Xcode does not accept these. The following snippet demonstrates a workaround.

set(Apple_wxWidgets_LIBRARIES)
    foreach(LIB ${wxWidgets_LIBRARIES})
        #message(STATUS "Checking ${LIB}")
        if(${LIB} MATCHES "-arch")
            message(STATUS "Skipping ${LIB}")
        else()
            #message(STATUS "Added ${LIB}")
            list(APPEND Apple_wxWidgets_LIBRARIES ${LIB})
        endif()
    endforeach()
    
    set(wxWidgets_LIBRARIES ${Apple_wxWidgets_LIBRARIES})


Thus, I think this issue is the same as in Issue 0007917
