Hello, Maybe this can interest somebody here. I have written a toolset to compile Boost libraries for the Sony PSP console using the unofficial SDK provided by the PS2DEV team (http://ps2dev.org), based on GCC. The toolset is itself based on the Boost's original GCC toolset. I've opened a project on SourceForge (http://boost4psp.sourceforge.net) where you can download this toolset (package boost4psp-toolset) as well as some binaries compiled for PSP (package boost4psp). Binaries provided for now are Boost.Graph, Boost.Signals and Boost.Test (my personal need was originally to use Boost.Signals on PSP). I will add some more libraries from time to time (for those that are not platform-specific, obviously). Regards Bruno
