Re: Binaries for SLES10

[Mário Costa]

>From my experience you will have a lot of problems compiling a static
version of octave, plus you will not be able yo add any of the
external available modules for octave, since it is required dynamic
linking, in order for those to be loaded by octave ...

I've managed to build from source a dynamic version for SLES 10,
although I was unable to use an up-to-date version of gnuplot, and
compiling that from source seems a nightmare ...

I cat tell you I've used SRPMS in one of the cluster nodes (build
node) to compile and create the rpms, some of the specs required minor
chages as they where only available for fedora or so ...

Then used the rmps created at that node to install in all the other
nodes of the cluster ...

Mário
