Performers,
                For input processing in my current program, I hacked the input code from /usr/share/Performer/src/pguide/C++/detail.C. I only use the input processing from here. In other words, I use pfuMouse and pfuEventStream to do auto input for a variety of Xformers. I needed the ability to switch between fly, drive, and trackball modes. This was the only program example that I found to do all this.

        My program (and detail.C) work fine as long as I compile -32, but if I try -N32 or -64, I have problems. They compile correctly, but when the view comes up, it is as if they receive no input data. I traced the programs through a debugger, and it seems as if the draw loop is doing it's thing fine. The program just doesn't accept any input. I next tried to compile some other program samples included with Performer to see if they allowed input compiled in this way. I compiled the programs in the libpfui directory. They work fine, but they don't use the same method for input. In fact they seem to use a much more difficult and cumbersome way to handle input and xformers.

        My question is, have I just run across a known limitation in the event processing code, or is there an error in the detail.C program sample???

I was unable to find any more samples that do input in this way, so I could not check the code for correctness. I really need to be able to compile N32 or 64 because I would like to use STL in some of my current code. It seems that the N32 and 64 bit SGI compilers only support the more advanced features of C++ needed.

        Can anyone help me???
