for this I changed my compiler to clang and included cs50 as #include "cs50.h"
instead of #include <cs50.h>
and it worked fine. need to include all c files in the task, eg in vs code, tasks.json file should look like:
{
"version": "2.0.0",
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: clang.exe build active file",
"command": "C:\\mingw64\\bin\\clang.exe",
"args": [
"-fdiagnostics-color=always",
"-g",
"${workspaceFolder}\\*.c",
"-o",
"${workspaceFolder}\\main.exe"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "compiler: C:\\mingw64\\bin\\clang.exe"
}
]
}
