okay so far ... > Then > 1) I created a new empty win32 application .exe project. > 2) set the configuration to Release > 3) specified multi-byte character-set in the Configuration > Properties/General Why do you do this? You'd better only do one step after the other. If it is not necessary, don't do it.

Again, don't do this (and you'd better delete all these fltkdll.dll copies, because you'd otherwise have old copies somewhere, and you never know which one is used). If you changed the OS PATH variable, you may need to reboot (I don't know, and I won't try this for you), but it is much easier to copy fltkdll.dll *only* to the same directory where you built your own application (.exe file). You may also need the other 3 .dll files you mentioned above, but I'm not sure. > I hope you can help me get these errors fixed. Okay, let's try this, and do only the steps I wrote above. Do not rebuild fltk(dll), since this is probably okay. I'm not sure if and where these compiler macros are defined, but please add them to your project for now, and let's see that later. If it doesn't work, please post your error messages again, and describe what you did so far.
