Installation (compiling)

There are some problems installing Kolab on Ubuntu 5.10 caused by the GCC compiler: openpkg 2.2 and 2.4 doesn't compile correctly with GCC 4.0, which is shipped with Ubuntu 5.10 (and other recent distributions). Fortunetely, you will find the 3.x version of GCC in the Ubuntu repositories.

Here is what I did to get things going:

sudo apt-get install bison flex g++-3.3 gcc-3.3 make shtool
cd /usr/bin
ln -s gcc-3.3 gcc
ln -s g++-3.3 g++

Then, I just continued to follow the installation instructions.

(Note: I am pretty sure that is all I did, but if it is not, please correct me).

I didn't get this to work. I installed from the Debian (sarge) packages, with:

 wget -r -l1 -nd --no-parent http://max.kde.org:8080/mirrors/ftp.kolab.org/server/release/kolab-server-2.0.1/ix86-debian3.0/

And then followed the installation instructions
