    Did you build llvm by simply using configure - make make install entered
    manually, rather than mk-dist?

    I had similar troubles as you (Visual C++ interference and
    "llvm-config not
    found") while running a native MXE build.

    MXE configure has an option "--enable-jit" but the output from
    'octave_config_info' from a cross build shows it just didn't work.
    I think src/octave.mk <http://octave.mk> has to be patched to
    (attempt to) build llvm support
    (i.e., add the --enable-jit flag to the configure options there). I was
    going to try that tonight (with an older MXE checkout) but I have little
    hope -it didn't work last time I tried.


I've a patch pending that does that. I just need to complete my octave
build first, then I'll submit it.
Below are the first two compile errors I get in a cross-compile with --enable-jit entered in src/octave.mk 
In MXE, compiling octave with llvm consistently goes wrong with faddeeva.cc.
Without patching src/octave.mk for llvm, octave builds fairly smoothly and runs OK on Windows.
Apparently something goes wrong with the llvm build flags (compile or link I don't know).
