cant debug Vlang code

[lucas8338]

i'm trying to debug a vlang code in vscode but my breakpoints in vscode are never being hit. (breakpoints are not working).

i have tried to compile the code using:
v -cc tcc -keepc -cg main.v
no success. breakpoints keeps not working.

how should i to configure the vscode to debug vlang?

my launch.json config:

{
"configurations": [
{
"name": "(gdb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/${fileBasenameNoExtension}.exe",
"args": [],
"stopAtEntry": false,
"cwd": "${fileDirname}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"miDebuggerPath": "C:/mingw64/bin/gdb.exe",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
},
{
"description": "Set Disassembly Flavor to Intel",
"text": "-gdb-set disassembly-flavor intel",
"ignoreFailures": true
}
]
}
]
}

my vscode version:

To debug comfortably, compile with gcc instead of tcc. tcc doesn't output debug info that the debugger likes.

Hi, try without the -c flag and use GCC to be sure:

v -cc gcc -keepc -g main.v

-c tells V not to create special #line directives in C code, and that's the problem.

See https://github.com/vlang/v/blob/master/doc/docs.md#c-backend-binaries-default

it worked, i thought gcc was being used by default by v, thats why i was using the '-cc tcc' flag.
ussing v -cc gcc -g main.v works.

tcc is used by default, because it is so much faster than any of the others. gcc/clang are used if you specifically add -cc <compiler name>, or if you add the -prod switch.
