![]() Next, I will show you how to build and run a Fortran project from the Code::Blocks IDE. You can see the default settings in the next image:īuilding a Fortran project with Code::Blocks: Next, select the Toolchain executables: first change the first three names starting with mingw32- by removing the above prefix and second change the Compiler’s installation directory to point to the MSYS2 installation directory, in my case this is C:\msys64\mingw64. This change will persist between projects, if you need to use an older standard remember to deselect the C 17 flag.Ĭonfigure Code::Blocks for building Fortran programs:Ĭhange the Selected compiler from GNU GCC Compiler to GNU Fortran Compiler. Now, when you press Build and Run the compiler will use the C 17 standard. Press OK and make sure the right rectangle is checked: Right click on one of the Have g follow … lines and select New flag: You can do this from Settings → Compiler and Compiler Flags. If you want to use the latest C 17 standard you will need to set a compiler flag. ![]() If you have no error, a console window will open and show you the result of running the program:īy default, GCC 9 compiles your C code using the C 14 standard, for C programs the default standard is C11. If you change something in your code, save it and use the Build and Run button to generate a new executable. Please note that the left, slightly larger, green triangle button is used to Run an already compiled program. Use the small green triangle button to build and run the project: You should see a default hello world source code. Next, go to the left panel, press the plus button to unfold Sources and double click on main.cpp to make it visible in the editor area. Press Next and, on the final page, accept the defaults and press Finish: Now, give a descriptive title to the project and select where you want the project to be saved, I’ve used Hello for name and C:\DEV for the project path: Select C (this should be selected by default) and press Next again. On the next page, read the description of the project type and press Next. Go to File → New → Project, select Console application and press Go: Let’s see how you can create a new C project. Press OK (lower right corner) to register the changes.īuilding a C project with Code::Blocks: Please note that the Make program entry remained unchanged! Here are the file names after I’ve removed the mingw32- prefix and changed the compiler’s installation directory: You can see the default settings in the next image: Select the Toolchain executables: first change the first three names starting with mingw32- by removing the above prefix and second change the Compiler’s installation directory to point to the MSYS2 installation directory, in my case this is C:\msys64\mingw64. Open Code::Blocks and go to Settings → Compiler: Let’s configure Code::Blocks for building C and C programs. At the end of the installation you will get an error about not finding a compiler, ignore the message and close this window.Ĭonfigure Code::Blocks for building C and C programs: Start the installation process and accept all defaults. On this page, select the version of the installer that doesn’t contain mingw in his name, typically this is the first option:
