Considering that i386 fink represents the most testing clang will ever see against GPLv3 software as a 32 bit compiler, I would say yes. Currently fink is broken for Xcode 4.2 on SL. We have two ways to go. 1) Backwards by implementing a path-prefix-gcc42 of gcc-4.2 based compiler wrappers only to be used for 10.6 running llvm-gcc as the system compiler. 2) Forwards were we try to do some good for the community by testing the clang compiler's i386 code generation. I would argue that if we don't do 1) then 2) causes little harm. So what if the package set if somewhat reduced initially. If the user wants the full set, let them revert to Xcode 3.2.6. This option at least allows those users who purchased Xcode 4 to leverage clang under SL. > > -- > Martin ------------------------------------------------------------------------------ The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.
