[LLVMdev] Can't compile Apple's version on Linux

[Duncan Sands]

Hi Andrew,

> CFLAGS="-w -m32" CXXFLAGS="$CFLAGS" CPPFLAGS="$CFLAGS" LDFLAGS="-m32"
> ../llvmgcc42-2335.15/configure --target=x86_64-apple-darwin11
> --with-sysroot=/home/tatsh/usr/x86_64-apple-darwin11

> --enable-languages=objc,c++,obj-c++

you forgot to specify the path to the llvm build directory.  This is done
by passing --enable-llvm=path on the configure line.

Ciao, Duncan.
