Hi all!
I am considering upgrading to OS X 10.7 (Lion). Will I be able to compile the PPL? Thanks in advance,
Fred, One caveat about building ppl under Lion with the system llvm-gcc is that -frounding-math support doesn't exist in the llvm-based compilers yet. So either you have to pass --disable-fpmath to configure with llvm-gcc/clang or build with gcc-4.2 which has a functional -frounding-math option. Note that Xcode 4.2 and later no longer provide gcc-4.2 so that option is problematic.
Right. In the Git version of the PPL (to be released as PPL 0.12), clang is automatically recognized so that explicitly passing --disable-fpmath will no longer be required.
The point is, though: does Fred need to use any of the PPL abstractions based on machine floating-point numbers? Cheers,
