I require OpenMP on OSX and had to build OpenMP/Clang to that end. The compiler reads as clang 3.5. For some reason, the compiler seems to have a problem linking executables with boost. I tried boost version 1.55 but got a compilation error. Boost 1.56 compiles with this warning:
but other than that compiles through and installs just fine. When trying to link an executable with program_options however, I get the following linker error:
Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64

I’m a little stumped as to how to fix this problem. Can someone help me out?
