I am following the tutorial here which shows how to use the VS C++ in Visual Studio Code.
Everything runs smoothly. The only problem is the auto-generated files (.lnk, .pdb, .exe and the likes) get generated in my src itself. How do I get the task to generate an output folder and store the auto-generated files there?
tasks.json:
{
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "cl.exe build active file",
"command": "cl.exe",
"args": [
"/Zi",
"/EHsc",
"/Fe:",
"${fileDirname}\\${fileBasenameNoExtension}.exe",
"${file}"
],
"problemMatcher": ["$msCompile"],
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
launch.json:
{
"version": "0.2.0",
"configurations": [
{
"name": "cl.exe build and debug active file",
"type": "cppvsdbg",
"request": "launch",
"program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,

}

I have an executable file a.out in my workspace that I am trying to call with the argument hello.txt.
When I run ./a.out hello.txt in the terminal, it works. However, when try to do this with VSC, hello.txt is not getting passed to the executable.
I've verified my json files extensively, but I cannot figure out where the issue is coming from. Any help would be greatly appreciated. My tasks.json and launch.json are below:
tasks.json:
{
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: gcc-9 build active file",
"command": "/usr/bin/gcc-9",
"args": [
"-fdiagnostics-color=always",
"-g",
"${file}",
"-o",
"${fileDirname}/a.out"
],
"options": {
"cwd": "${fileDirname}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "Task generated by Debugger."
}
],
"version": "2.0.0"
}
launch.json:
{
"name": "C Launch",
"request": "launch",
"program": "${workspaceFolder}/a.out",
"args": ["${workspaceFolder}/hello.txt"],
"cwd": "${workspaceFolder}"
}
I saw other posts like this that explain how to debug with gdb. But it still wont work with me. I installed the following extensions:
I created the following launch.json:
{
"version": "0.2.0",
"configurations": [
{
"name": "Run GDB",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}\run.exe",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"externalConsole": false,
"MIMode": "gdb",
"preLaunchTask": "compile_with_gfortran"
}
]
}
and the following tasks.json
{
"version": "2.0.0",
"tasks": [
{
"label": "compile_with_gfortran",
"type": "shell",
"command": "gfortran -o run.exe example.f90 -g",
"options": {
"cwd": "${workspaceFolder}"
},
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
Both json files are inside the folder .vscode. By hitting shift-ctrl-B the task builds correctly and creates the executable. When I click F5 to start the compiler, the preLaunchTask runs, the compiling buttons (step in etc...) show up but nothing attaches to the Fortran file, although I added breakpoints into proper locations. And nothing shows up in the debug console. Any suggestion?
VSCode : 1.61.0

I'm trying to build c++ program using by VSCode.
when the run build, VSCode showing this message.
I know build tasking need matching launch.json file's preLaunchTask with tasks.json file's label. and I'm already set it.
tasks.json

The problem is, if I change the "type" value in tasks.json, from shell to cppbuild, It doesn't work and show the error message like to.
showing error message when the run build
what is different "cppbuild" and "shell"? and What should I do how using "cppbuild" value?
Te values of cppbuild are fine. Try changing in launch.json the value:
"preLaunchTask": "C/C++: g++ build active file",
to:
"preLaunchTask": "cppbuild",
The difference between shell and cppbuild is that the first open the BASH and runs a command you write, the second, cppbuild, runs an specific binary (or program).
Eclipse CDT can automatically compile all the changed source files (if there are) in the project directory and link them. However the default "C/C++: g++.exe build active file" task would always compile the file even there was no change since last compile. Yes, it could be done by make file. Besides that, do VSC or its extensions provide some easier way to do so?
Here is how my tasks.json looks like:
{
"version": "2.0.0",
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: g++.exe build active file",
"command": "\"${config:task.gccpath}/g++.exe\"",
"args": [
"-Wall",
"-g",
"${file}",
"-o",
"${workspaceFolder}/Debug/${relativeFileDirname}/${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "${config:task.gccpath}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "compiler: ${config:task.gccpath}/g++.exe"
}

}
And here is how my launch.json looks like

Im new to stackoverflow and VS Code. When I tried to debug my code I got error message, and couldn't fix it.
I uploaded the error message

my main.cpp file is simply printes "Hello"
I installed MinGW and its directory is : C:\MinGW<
I hope there is someone who can help me.
I encountered the same problem recently. It seems that the auto-generated tasks.json is not set correctly and the executable is created in the root directory. This can be fixed by changing the type from "cppbuild" to "shell".

"tasks": [
{
"type": "shell",
...
}
