I found the stlport of 4.6 for PS2, but I'm having trouble locating stlport for PSP (or an equivelant STL library). I tried several variations of the PS2 gcc make files with the PSP gcc compiler, but none worked.
I searched the rest of the forums, and in one case someone said they found STL, but didn't say where.
Do you explicitly need STLport? Cause "regular" stock STL is included in the pspsdk and works just fine if you're compiling a C++ program. (using psp-g++ etc)
I've been working with the Ogre 3d engine and I recently ported that library to PocketPC. I thought I might try to port it to PSP which would enable more Ogre developers to bring their 3d games to a new platform.
