Hello Robert,

My, how time flies! :-)

I would assume so. That's what I had done about 6 years ago when I was  
working on a renderfarm management software that ran on IRIX. Moving  
to gcc involved some work to get it to compile the first time (about 2  
weeks IIRC) but after that it went smoothly. For OSG since it already  
compiles with g++ on other platforms I assume compiling it with g++ on  
IRIX would be pretty painless, depending on the version of g++ that's  
available on IRIX...

But I would assume performance would suffer a bit as g++ will probably  
optimize a bit less than IRIX's own compiler. At least, that was the  
case for the project I worked on, but it didn't make enough of a  
difference to be significant. For an OSG project it might be more  
important, but that's up to the actual user to test out, compare and  
determine if it makes a difference for them.

That's good, especially if it works well as-is. I was not suggesting  
dropping support for anything, just giving my impressions on the usage  
experience.
