Hi, I apologize if this is a FAQ - I couldn't find much on other compilers I am interested in using boost with a compiler for a DSP - The compiler is somewhat archaic - I'm not using RTTI or exceptions (the compiler supports them but it is currently broken) - the STL has old iostreams and no doubt I will find some other musty corners. I don't have any illusions about getting the whole of boost to compile but I'm sure there are some large pieces that will work OK. I have no problem doing the port myself. I have successfully got shared_ptr and shared_array to work but I needed to make 3 fairly trivial changes to the code to get it to compile. Are boosters interested in folding these changes back into the main source in the interests of making boost more portable or am I on my own here since I am working with an unsupported compiler? I can post the problems I ran into if anyone is interested. Andrew
