I think we may need more input. Both of you are running Slackware 9.0 where I am using debian. I have tried it and got it running on both woody and sid with g++ 2.95.4 and 3.3.1. I am thinking it must be something different about the compiler flags on slackware but I'm not sure what to suggest. Has anyone tried this on Redhat?
