Hello all, Some dumb questions related to my ongoing migration away from Windows. Something that I have found useful is to write numerical analysis code (internally using templates, streams, etc.) in C++, and then compile them as extern "C" something like extern "C" _export void DoSomething(float * data, int rows, int columns) { // C++ specifics are legal herein; arguments // and return type must be legal for C - e.g. no references // and no classes; structs are ok. } On Windows with MinGW, the exporting of the function above seems to be almost magically easy. Do similar tricks work on Linux? On Linux, I intend to use gcc and Code::Blocks, unless somebody has a better idea. I bring this up in part because some things (tight loops) are best left to statically typed languages, C++ has a slight edge over Smalltalk on syntax for translating equations, I already have a lot of working C++ code, and I might be able to ease into getting GSL talking to Pharo before having to tackle the entire interface. I am hoping to add something to an evolving library, recompile, and perhaps after restarting Pharo have access to the new function(s) with fairly little hassle. Is that reasonable to ask? Any advice or warnings? Bill
