I have always compiled and run my C project manually in this way:
gcc -o main file1.c file2.c main.c
./main
If I open my project on VS Code and try to compile and run it by pressing the "play" button, VS Code first writes on terminal:
gcc main.c -o main
which will make obviously fail the compile, because the other needed files (file1.c and file2.c) are missing in compilation.
Where (on VS Code) can I customize the compile and run process made by the "play" button from the Code Runner extension?
For customizing the Code Runner play button, modify your code-runner.executorMap
setting.
But I'd instead recommend a build task, since Code runner is more suited to building and running individual files, and by editing the executor map for a specific set of files would kind of be subverting its purposes, whereas this kind of thing is what build tasks are designed for.
A build task for you might look something like this:
{
"type": "shell",
"label": "C/C++: gcc build main",
"command": "gcc",
"args": ["-o", "main", "file1.c", "file2.c", "main.c"],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": ["$gcc"],
"group": {
"kind": "build",
"isDefault": true
},
}
