llvm-config outputs the flags that were used to compile LLVM, not the
flags you need in order to compile against LLVM. So, for example, it
outputs -O2 -g on my system amidst its --cflags, which makes it
impossible to make a debug build. I'm not the first one to complain
about this:
http://llvm.org/bugs/show_bug.cgi?id=4276
http://llvm.org/bugs/show_bug.cgi?id=9405
http://llvm.org/bugs/show_bug.cgi?id=8220
That's what.
Since we now care about LLVM, I'd like to fix its build system. Making
llvm.pc seems easier than trying to fix llvm-config.
Fair enough, though I was not talking about --cflags, but --ldflags. Now, if you manage (God knows when) to get pkg-config into llvm, this will make octave dependent on bleeding-edge not-yet-released LLVM. I think I'll go with a local/patchy solution instead.
