I have a method which uses FABS

return  (fabs(x - y) <= EPSILON);

It compiles and builds fine on four of my machines, but when I recently tried to configure another new machine i get a weird build error whereby it says "ApplicationBackgroundColor.m:146:14: Called object type 'int' is not a function or function pointer"

On closer inspection it seems that the FABS is pointing [when i command click it in Xcode] to tgmath.h; while for the other machines that is working it is supposed to be redirected to math.h in /usr/include of the iOS simulator.

The entire repository is directly cloned from git and there are no difference between those working and those not working - the code and the project workspaces. Therefore, as far as I can tell, there must be something else I'm missing.

Could someone help me?

Try doing it:

Open terminal

type --> xcode-select --install

It could be related to not find the math.h where it is defined

It is for installing the command-line tool again. Many times it solves this kind of problems. And after doing it restart XCode
