Question

I get to the very last linking command (the actual executable is being linked) but i get a BUNCH of undefined symbols (and they’re in cpp and look so scary to me, a simple c programmer)

–its probably something simple but i cant get what im supposed to put as linker (its using gcc here…? is that appropriate? g++ told me too many input files lol) (ld returns much of the same)

anyway its ridiculous, i am completely stuck

thankyou for your help!

Seems you are trying to link C++ code with a C (gcc) linker call. That’ll not include the appropriate libraries which is just what you are seeing. Try g++ instead of gcc (or throw out the C++ code/libraries).
