[quote="Setharian"]alignment still matters, but I clearly see no reason why you just cannot use the c dll after fixing alignment issues or use C++ builder to compile it into .obj files and ]

exactly because of that precise reasons, i am going to make changes to the car dynamics code, which i'd like to have in pascal, there is NO UNIFORM linking for at least 3 platforms on which i'd like to use this on (meaning i'd have to compile and link separately on each platform) also there are certain security issues if u use an externally linked library - people might just replace it with a hacked version and cheat.. delphi can link bcb obj files, but fpc DOES NOT link obj files made with delphi or bcb (wrong format). those dvector, dmatrix etc.. files are not part of newton, but of the sdk examples, i translated them already (but the translation might be broken)
