I didn't quite know where to post this info or ask for help, and this seemed like the best place to do so, so forgive me if this is off-topic.

I've successfully recompiled the gcc3.4.5 suite to include the g77 fortran compiler natively on pdaxrom. I'm very new to building gcc from source, and it's a little overwhelming, so it took me several tries to configure to a point of semi-usability, wherein the "g77" command could actually produce object code (*.o).

I did this using the pdaxrom gcc3.4.5 cross compiler for x86. However, it does not seem to work with the existing libgcc AFAIK, giving linker errors, and keeping certain applications as "qpkg" from running until the compiler is un-installed.

Does anyone have any advice about rebuilding gcc for an existing platform such as pdaxrom? I'm fairly aware that OpenZaurus already has this working, so it is not my intention to do so for that platform, I'm just trying to focus on pdaxrom.

My questions are:
* What purpose exactly does "libgcc" serve natively?
* What effect does it have to replace the existing library?
* How can I replace the existing "libgcc" or link to it with the g77 compiler?
* Is there a simple way to get OE to do this for me?
