Hi Folks,

Has anybody tried to run QGIS (Quantum GIS) on Debian
(latest version)/ultrasparc using either the Debian
package or the recompiled source code?

A 'bus error' appears everytime a graphic file is
opened; any hint or help will be appreciated.

A 'bus error' message on sparc is usually a result of an attempt to read or write from/to an unaligned memory location. Sparc has strict alignment requirements, for example object of size 4 must be begin at a memory address divisible by 4, etc. The most common mistake leading to such a condition is casting the pointer to object of one size to a pointer to an object of larger size and dereferencing it.

You should try and rebuild the package in question with debugging symbols, try to run it under gdb and trigger a failure. The backtrace then should tell you where the problem is, usually it's enough to figure out what went wrong there.
