Has anyone tried to build a Universal Binary with the following:
CMAKE_OSX_ARCHITECTURES:STRING=ppc7400;i386
instead of the usual:
CMAKE_OSX_ARCHITECTURES:STRING=ppc;i386
If I do a 'lipo -info' on the build result it tells me "Architectures in
the fat file: foo.a are: ppc i386". It should say "ppc7400 i386", which
I do get when I build with Xcode instead of CMake.
(ppc7400 is for the G4, which is the oldest CPU I want to target, I
don't care about the G3.)
Anyone else tried this? Thanks,
Replying to myself... :(
It seems this actually partly works. Let's say I'm building VTK. I've
set CMAKE_OSX_ARCHITECTURES:STRING=ppc7400;i386. I do 'make' and in the
resulting /bin directory are, amongst other files:
CommonCxxTests (an executable)
libvtkRendering.a (a static lib)
If I do 'lipo -info' on each, I learn:
$ lipo -info /Users/sean/kitware/VTK-pristine-bin/bin/CommonCxxTests
Architectures in the fat file: /Users/sean/kitware/VTK-pristine-bin/bin/
CommonCxxTests are: ppc7400 i386
$ lipo -info /Users/sean/kitware/VTK-pristine-bin/bin/libvtkRendering.a
Architectures in the fat file: /Users/sean/kitware/VTK-pristine-bin/bin/
libvtkRendering.a are: ppc i386
Very strange! It seems that for all executables it is 'ppc7400' as
expected, but for all static libs it is 'ppc'.
Any ideas why?? Thanks,
Did you try a make VERBOSE=1 to see what flags were being used during
the building of stuff to find out where it went wrong?
