Hi Yves,
I thought the
CMAKE_OSX_SYSROOT:STRING=/Developer/SDKs/MacOSX10.4u.sdk/
flag should set it to use the apple universal SDK
if you indeed have that installed,
so you should be able to build universal binaries on a PPC Mac
just the same as you build universal binaries on a intel Mac?
Or am I missing something important, as usual...
As for code optimisations, where are the differences in these between
say a linux i386 build and an OSX i386 build.
Same VTK C++ code being compiled, same processor...?
The APIs that the VTK compiles libraries see for openGL, python, etc.
should be platform independent?
What am I missing here? Quite a lots of important details I expect.
I hope it might be possible to still use the compiler flag -fast
to optimise both PPC and i386?
But as mentioned before it might be better to have a special case in
cmake for OSX,
where if you are building a universal binary, you have options to set
the compilation and some other needed flags differently for ppc and
i386?
I think you can do that in XCode, and even set them for specific c++
files.
I wish I was a C++ programmer so I could actually do something here....
I'm only a biologist...
A simple vtkPython script is about my limit.
