As the title says, I can’t compile the project after adding code to it, I tried many things that I read on the forums and I can’t find the solution, before I couldn’t open the project but I was able to solve it, now I have this other problem which is that I don’t I can compile the project.
Looks like you have a linking error which indicates you’re using a function from a library but it hasn’t been properly accounted for when linking against available libraries. What does the log look like? Usually it will tell you which function is in question. From there you can track down which library you need to add.
