gfortran linking and compiling subprograms in Visual Studio Code - json

Question

I would like to compile and run fortran subprograms using Visual Studio code.
When I try debugging the code, I get an error stating that the "prelaunch task 'gfortran' terminated with exit code 1", with the following console message:
c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../libmingw32.a(main.o):(.text.startup+0xa0): undefined reference to `WinMain#16'
collect2.exe: error: ld returned 1 exit status
The terminal process "C:\MinGW\bin\gfortran.exe '-g', 'D:\......\params.f95', '-o', 'D:\.......\params.exe'" terminated with exit code: 1.
When I click 'show errors' it says that 'no problems have been detected in the worskpace so far'
My json file configurations for the folder are as follows:
Launch.json
{
"version": "2.0.0",
"configurations": [
{
"name": "Fortran Launch (GDB)",
"type": "cppdbg",
"request": "launch",
"targetArchitecture": "x86",
"program": "${workspaceRoot}\\${fileBasenameNoExtension}.exe",
"miDebuggerPath": "gdb.exe",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceRoot}",
"externalConsole": true,
"preLaunchTask": "gfortran"
}
]
}
tasks.json
{
"version": "2.0.0",
"command": "gfortran",
"args": [
"-g",
"${file}",
"-o",
"${workspaceRoot}\\${fileBasenameNoExtension}.exe"
]
}
I tried many of the fixes found from the web, such as changing the default setting to save file before run, reinstalling gfortran etc., but to no avail. When I try compiling from the command prompt, I do not have any errors, but when I use the flag -g, I have the same error about 'undefined reference to WinMain#16'. Also, I have no problem using the settings to run a single fortran code (without subprograms).
I have a Windows-32 architecture, and I have used MinGW to install gfortran. I have set the System Environment Variable 'Path' to include this folder.
I hope the problem is clear, please help me with this.
