SUMMARY: Ximian Gnome on Solaris 9

Hi, many thanks to:
David Leach, Doug Otto, Jonathan Jackson, Brett Lanham.

Here is the solution for this problem (I suppose):


> if you're in a bind, and can't wait, you could intercept the library call
> it's making using LD_PRELOAD.  ie, if it's calling uname(2) then create a
> shared object with uname(2) and by preloading it you can fool the
installer
> into thinking you're running 5.8.
>
> if it's doing it another way, (ie, looking at sysinfo(2) or something
else)
> you'll basically just need to adapt what i've done below for that call.

> I guarantee nothing except that this might screw things up.  no
warranties,
> no nothing. if it works, good.  if not, too bad.  okay?

> You can try to fool uname...I have heard of that working.  I installed

> You do not have to have the whole Ximian gnome distribution to get
evolution.
> Have you tried installing just the packages neccessary to get evolution
working?
> I've got evolution working fine on my home PC (redhat 7.2) and I never
installed Ximian.
> I did use RPM however.  You should be able to find source tarballs for all
the needed

should be able
