Compiling in OS X
I could not compile Cxx in OS X as it complained about not finding LLVM library and other issues with the system clang compiler. I found a workaround (though there is still some Cxx functionality that does not work) by compiling Julia with USE_SYSTEM_LLVM:=1 and BUILD_LLVM_CLANG := 1, but I had to manually change baseclangdir to my local dir to make Cxx work. I think this might be easily fixed to automatically look for the system LLVM
PS: the same happens with 0.5 0.6 and 0.7 Julia versions
Can you post the exact error message you originally say? Cxx does not currently support julia 0.7.
This is what I get with the Julia 0.5.2 system binaries:
