Title: Cannot find the compiler
Post by: Lyta on February 14, 2026, 05:44:25 pm

I've installed this compiler : https://www.equation.com/servlet/equation.cmd?fa=fortran 15.2.0
When i type in gfortran -- version in a cmd prompt it says:
GNU Fortran (GCC) 15.2.0

But when i select the GNU fortran compiler in CodeBlocks it gives this message when i try to build and run:
The compiler's setup (GNU Fortran Compiler)  is invalid, so Code::Blocks cannot find/run the compiler.
  Probably the toolchain path within the compiler options is not setup correctly?!
  Do you have a compiler installed?

What compiler do i actually have installed? I dont understand the difference between the mingw compiler and the one i actually have? Under the toolchain paths it shows for the mingw executables, but i don't think it's the one i actually have, i installed the compiler i linked earlier before codeblocks.

Go to Settings -> Compiler, select the "Toolchain executables" tab and fill the controls with your compiler's location (use where gcc.exe in the cmd prompt) and program's names.
