->Hello all,
-> I have some questions in regards to Performer 2.0(Beta version)/Performer 2.0 and changing from a 5.3 environment to a 6.2. Are there significant differences between Performer 2.0(Beta) and 2.0? How does IrisGL and OpenGL play a role. Performer can deal with both IGL and OGL, right? Original development was done in the Performer 2.0(Beta)/ 5.3 environment.

Yikes - what beta?
Regardless, I very strongly recommend (beg) that you move to 2.0 MR!
Note that you do have to compile separately for IRIS GL and OpenGL
all .o's that include Performer header files.

-> I have run into a lot of problems trying to understand the similiarities and differences between porting from 5.3 to 6.2. We have changed to a couple of platforms with 6.2(Onyx, Crimson, Max Impact) and it seems we need to carry over the 5.3 "baggage" in order for it to work, I guess that is because we incorporate function calls in our "stealth" application for 5.3. Would we need to change our application function calls to adhere to 6.2 in order to get out of constantly bringing the 5.3 libraries?
-> On the Max Impact(6.2)
-> I got these:
->ld: WARNING 84: /usr/lib/libInventor.so not used for resolving an symbol.
->ld: WARNING 85: definition of _checktraps in /usr/lib/libfpe.so preempts
-> that definition in /usr/lib/libc.so

It is not generally supported to link on a new OS and run on an old OS since obviously
old OSs can't predict what will show up in a new one (such as libfpe.so).
However, new versions of IRIX should be able to run old programs.

->
->ls: ERROR 33: Unresolved text symbol "pfPushState" 1st referenced by label.0

Hmmmm. This just looks like libpf.so is missing on the link line!
