Data: running 64bit Ubuntu 12.04
David, I thought I'd share a couple LLVM package-related tips. Please check if the package is llvm-3.X or libllvm3.X. If it warns you that unrelated things like Xorg and ubuntu-desktop will be removed it's trying to remove libllvm and not just plain llvm.
I just purged my old llvm-3.0 and installed llvm-3.2 with this:
sudo apt-get purge llvm-3.0*
sudo apt-get install llvm-3.2 llvm-3.2-dev llvm-3.2-doc
No dependencies required like llvm-2.9 etc.
If you have a program somewhere called just plain "llvm-config", make sure it's the correct version. Sometimes it's a symlink to the old version instead of the latest version. Even better, specify llvm-config-3.2.
I updated my Octave config script to use 3.2 instead of 3.0:
../octave/configure [bunch of options here, ending with:] LLVM_CONFIG=`which llvm-config-3.2`
and configured and built it. Works fine. Can't tell any difference between llvm 3.0 and llvm 3.2 though.

The attached config.log shows no evidence of being called with LLVM_CONFIG either as an environment variable or as a command line argument. So what you see is the expected behavior with LLVM 2.9, which is what your invocation of configure detected and found to be too old to use.
Can you try configuring again with LLVM_CONFIG added to the environment or the configure command line and attach that config.log file?
Either
or
should work and one or the other will be required for Ubuntu 12.04. I see now that Rik omitted the "export" in comment #15, if that's what you did then that might be why it wasn't found by configure.

Sorry, no it didn't fix itself, I just gave up and didn't notice the most recent two comments.
I just now tried following Rik's instructions and the message is still there. I've attached all the files you asked for.

No response from original reporter. I assume the problem has corrected itself. Closing report.

I just did a fresh clone and configure on an Ubuntu 12.04 VM and I don't get the error message reported here. It looks like it is finding LLVM 3.2 properly for me.

This is just weird because Debian and Ubuntu are easy platforms for lots of people to build Octave on.
I think we need to start at the beginning.
This will grab brand new sources so there is no cruft around. It attempts an in-tree build which is simpler than a VPATH build. It also disables java, just in case this is an issue. I gather you are using a Bourne sh equivalent so I've written the commands to also send stderr to the log files so we will have everything captured. If the end of the configure summary still says that JIT is disabled then upload the following files.
dpkg.list
bootstrap.dbg.log
configure.dbg.log
config.log

Ok, can you please attach the file config.log that is generated from this configure run with llvm-config-3.2 passed to it? There are more details in the log file than what is displayed on stdout and stderr.

Rik re comment #10
So you don't have llvm or llvm-dev installed (as Mike suggested in comment #3).
I installed llvm-3.1-runtime and libllvm3.2-dbg (so now I have the exact same packages) and I'm still getting that warning message (from comment #0 , same stdout log as comment #2). Could you please look at comment #9? Is there anything else you did or that I might need to do? If not, can you try repeating my steps?
Thank you,
David

re comment #11
The warning message was printed to stderr
confdebug.log only contains stdout

David, re comment #8, I don't see the warning message you mentioned in the config log that you posted as an attachment. That config output looks correct to me and it looks like LLVM 3.2 is detected and configured correctly. The log also says in the summary at the end that JIT is enabled. Can you check whether the log or the warning message are correct?

So on my Mint 13 (Ubuntu 12.04 equivalent) machine I have the following llvm packages installed
The -dbg package is optional. You might check that you have these and no other packages. Version 2.9 isn't a requirement for me.

I noticed that the status of this bug is still set to "Works For Me" so I tried installing Octave on a fresh Amazon EC2 instance (Ubuntu 12.04 32-bit) and ran into the same problem. Here's the full list of everything I installed on it:
mercurial gcc g++ gfortran libpcre3-dev libblas-dev liblapack-dev libqt4-opengl-dev libreadline6-dev libqhull-dev libfftw3-dev libglpk-dev libsuitesparse-dev libarpack++2-dev libgraphicsmagick++1-dev libqrupdate-dev flex bison gnuplot gperf ghostscript libfontconfig1-dev libfltk1.1-dev texinfo libqscintilla2-dev pstoedit epstool transfig texlive autoconf automake make openjdk-6-jdk libcurl4-openssl-dev libhdf5-serial-dev llvm-3.2 llvm-3.2-dev libgl2ps-dev
I also added
JAVA_HOME DEFAULT=/usr/lib/jvm/java-6-openjdk-i386
to .pam_environment
When I ran ./configure
I got
configure: WARNING: llvm-config utility not found. JIT compiler is disabled.
configure: WARNING: llvm-config utility not found. JIT compiler is disabled.
So then I added llvm
and still got the same error message
So then I added llvm-dev
and still got the same error message
Are you getting llvm from another non-standard PPA by any chance? Have you changed anything in bin? How can you have it installed without llvm-2.9 which is a dependency?

I ran it with LLVM_CONFIG=llvm-config3.2 and got the following warning

If that's the case, then you're going to want to specify LLVM_CONFIG when you configure, for example
if llvm-config-3.2 is in your PATH, or
to set the full path explicitly. Try that please and let us know if it works for you.

Tue 26 Nov 2013 06:51:05 AM UTC, comment #6:
When I do that, it removes llvm and llvm-dev as well. Isn't there some way I can tell the configure script where I want it to look for llvm so that it will use the right one?
|
Tue 26 Nov 2013 06:16:46 AM UTC, comment #5:
llvm-2.9 is too old. In some way you need to remove that package. Maybe you can just use
to remove that one version but keep 3.1 and 3.2.

Tue 26 Nov 2013 06:05:27 AM UTC, comment #4:
I still get the same error message. llvm has llvm-2.9 as a dependency.
I've attached the new confdebug.log
(file #29715)

Tue 26 Nov 2013 01:51:14 AM UTC, comment #3:
The log says you are missing the llvm-config program. On Debian, so probably also on your version of Ubuntu, llvm-config is provided by the llvm package, which is supposed to pull in and configure whichever version of LLVM is the default for your Ubuntu version. Try apt-get install llvm (and llvm-dev, same reason) and see if you get better results.

Tue 26 Nov 2013 01:46:45 AM UTC, comment #2:
Yes, I did have llvm-2.9-dev installed
I completely removed llvm-2.9-dev, but I'm still getting that error message.
(I also have libllvm3.1 installed but important things such as xorg depend on it so I can't remove it)
I've attached confdebug.log

I'm also building with on Ubuntu 12.04 with llvm-3.2-dev and it works for me.
Is it possible you have more than one llvm installation? I have LLVM 3.1 and 3.2 installed, but only the -dev version for 3.2. Maybe you have two -dev packages installed.
Also, if you do
are there any other lines in the log that contain llvm? For example, it might say

Mon 25 Nov 2013 09:11:46 PM UTC, original submission:
Even with the most recent version of LLVM available in the Ubuntu repo (llvm-3.2-dev), I still get the warning: "configure: WARNING: LLVM was not found or is to old. JIT compiler is disabled." when running ./configure
I can't find any documentation that lists the required version
