I'm writing a C++ program that needs to compile and link with LLVM, and trying to figure out how to build it with autotools. The good news is, llvm-config will supply the relevant compiler and linker flags. The bad news is, the llvm-config in the current path is not likely to be the right one (e.g. Ubuntu 14.04 thinks LLVM 3.4 is the latest version whereas it's actually up to 3.8, and the differences between versions do matter) so the user or packager needs to supply a path to the correct llvm-config. What's the best way to do this? I was given a link to a macro that tries to do this... https://github.com/google/autofdo/blob/master/m4/ax_llvm.m4 https://github.com/google/autofdo/pull/30/commits/0029f4be825f851b9d99bcd19dcb34fd59f1775e ... But it doesn't work, and I don't know enough M4 to figure out why. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
