What version of LLVM is needed these days?

I have llvm 3.0; configure output at the end doesn't mention the
llvm
libs/flags/include but only says something like:
"JIT compiler for loops: false"

AFAICR a week or two weeks ago it did pick up the llvm stuff
(that is, I saw
the llvm libs/include/flags mentioned in configure's output).

linux Mageia 2, gcc 4.6.3, Pentium M

LLVM 3.0 should still work, I haven't tested it recently though.
Recently there was a change that requires "--enable-jit" in order for
JIT to be enabled.
Thanks, yes --enable-jit=yes did the trick.
I must have missed that announcement somehow.

BTW I now see messages (using sources updated two hours ago):
"cc1plus: warning: /usr/bin/llvm-config: not a directory {enabled by
default]"
repeated twice after every compile step. Should I start worrying?
Yes. That is unlikely to work. We can wait until the end of the compile,
but I think I want to see your config.log file.

Wiped the build dir, ran ./autogen.sh and started a new build.
The cc1plus warnings are gone now.
Tomorrow morning I'll see how far the build went. So until then, just ignore my previous post.

Thanks,

Philip
