SGIoberon in the directory above (Oberon/SiliconGraphics) has been compiled under IRIX 4 and can run under IRIX 4 or IRIX 5. However, this version of SGIoberon does not support IRIX 5 shared objects. If you have IRIX 5 running and you would like to use shared objects from within SGIoberon, you may want to install the IRIX 5 version of SGIoberon, which provides support for shared objects. To do this, you have first to install (uncompress and tar xf) the IRIX 4 version in /usr/local/Oberon. You have then to copy IRIX4to5.tar.Z to /usr/local/Oberon, uncompress, and tar xf it. This will overwrite a few oberon files. You also have to recompile your Oberon sources if they were compiled with a version older than 4.2. SharedObjects.Mod is an example of how to use shared objects. Regis Crelier
