Compile condor 7.1.0 on openSUSE 10.3

Condor has traditionally only been available as binaries, most of the time this is fine. We successfully run the Mac OS X PowerPC & Intel binaries and for openSUSE 10.x use the Red Hat 9/dynamic binaries. However for 64-bit openSUSE the binary (RH5) doesn't really work, it struggles to start up. Since the release of condor 7.x they have included the source, so that seemed a sensible avenue to explore. It does compile, but it is a bit more involved than just configure; make; make install!

These instructions should hold true for 7.0.0, 7.0.1 & 7.0.2 as well.

Grab the source for the latest stable or development release (I personally go with the development release).

First off glance through the README, check you have all the prerequisites. I also found I needed to add termcap, terminfo, ncurses-devel and flex (grab them from yast).

Now lets start configuring:

cd src
./configure --disable-gcc-version-check --disable-full-port --without-classads

The configure flags mean:
  1. Our gcc version is newer than the built-in checks.
  2. No standard universe/checkpointing. Standard for a new OS port not to have these.
  3. ClassAds not yet supported (no condor_q -better-analyze).
You will get an error:

configure: error: Condor does NOT know what glibc external to use with glibc-2.6.1

To get around this edit with your favourite editor. Around line 2500 add this option for the case statement:

"2.6.1" ) # openSUSE 10.3

Now run build_int and configure again as above.

If that runs you can then execute make. Sit back as this may take a while!

If there is a problem, typically on the externals part view the log which will be indicated. You may need to install something (such as the packages I mentioned earlier).

Compilation is finished when something like this pops up (and no obvious errors)

make[1]: Nothing to be done for 'all'.
make[1]: Leaving directory '/home/build/condor-7.1.0/src/condor_examples'

Everything is compiled so now prepare the release:

make release (output to release_dir, dynamically linked with debugging, ready for testing)
make public (output to ../public, add stripped dynamic/static linked binaries and no debugging)

Find your final installation bundle in ../public as condor-7.1.0---dynamic.tar.gz. Unpack and use it as you normally would. condor_version, will reveal your custom compile:

$CondorVersion: 7.1.0 May 21 2008 $
$CondorPlatform: X86_64-LINUX_SuSE_UNKNOWN $

Need help/advice? There is an excellent presentation which covers this as well as the users mailing list which is both active and helpful.

Hopefully in the future condor will have better support for openSUSE so that a full port (standard universe/checkpointing) and ClassAds will be available.

Good luck!
