Can I work in Visual Studio 2019 and gfortran (gcc) compiler?

Question

Is there any approach to work on visual studio with gfortran? I have Windows 10, Visual Studio 2019 and gcc 7 installed using Cygwin.

Answer 1

Let assume Cygwin installation path is D:\Cygwin and gcc-fortran package is already installed in Cygwin.

• Add the Cygwin installation folder in %PATH% environment variable in Control Panel.
• Create HelloWorld.f90 file in a folder:

program hello
print *,"Hello World!"
end program hello

• Open that folder in VSCode.
• Go to Terminal > Configure Tasks > Create task.json file from template > Others.
• VSCode will automatically create and open a tasks.json file in .vscode folder.
• Add this JSON code:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "D:\\Cygwin\\bin\\gfortran.exe",
            "args": [
                "HelloWorld.f90"
            ],
            "group": "build",
            "presentation": {
                "reveal": "always"
            }
        }
    ]
}

• Add other required parameters in args field in the above JSON file.
• Go to Terminal > Run Build Task or press Ctrl+Shift+B to build it. Click on build.

The gfortran path will be different if different package is installed. Optionally, fortran extensions can be downloaded from Visual Studio MarketPlace for syntax highlighting. For further information, read tasks in VSCode
