I'm trying to compile c++ inside VS Code.
I have MinGW installed.
I've followed the steps in this video: https://www.youtube.com/watch?v=rFdJ68WbkdQ
And the steps at the "getting started" docs https://code.visualstudio.com/docs/languages/cpp
Actually, my config shows like this:
{
"configurations": [
{
"name": "Mac",
"includePath": [
"/usr/include",
"/usr/local/include",
"${workspaceRoot}"
],
"defines": [],
"intelliSenseMode": "clang-x64",
"browse": {
"path": [
"/usr/include",
"/usr/local/include",
"${workspaceRoot}"
],
"limitSymbolsToIncludedHeaders": true,
"databaseFilename": ""
},
"macFrameworkPath": [
"/System/Library/Frameworks",
"/Library/Frameworks"
]
},
{
"name": "Linux",
"includePath": [
"/usr/include",
"/usr/local/include",
"${workspaceRoot}"
],
"defines": [],
"intelliSenseMode": "clang-x64",
"browse": {
"path": [
"/usr/include",
"/usr/local/include",
"${workspaceRoot}"
],
"limitSymbolsToIncludedHeaders": true,
"databaseFilename": ""
}
},
{
"name": "Win32",
"includePath": [
"C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.11.25503/include/*",
"C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.11.25503/atlmfc/include/*",
"C:/Program Files (x86)/Windows Kits/10/Include/10.0.16299.0/um",
"C:/Program Files (x86)/Windows Kits/10/Include/10.0.16299.0/ucrt",
"C:/Program Files (x86)/Windows Kits/10/Include/10.0.16299.0/shared",
"C:/Program Files (x86)/Windows Kits/10/Include/10.0.16299.0/winrt",
"${workspaceRoot}"
],
"defines": [
"_DEBUG",
"UNICODE"
],
"intelliSenseMode": "msvc-x64",
"browse": {
"path": [
"${workspaceRoot}",
"C:\\MinGW\\lib\\gcc\\mingw32\\6.3.0\\include\\c++",
"C:\\MinGW\\bin"
],
"limitSymbolsToIncludedHeaders": true,
"databaseFilename": ""
}
}
],
"version": 3
}
And the "tasks.json" file has the following:
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "build",
"type": "shell",
"command": "g++",
"args": [
"-g", "Calculator.cpp", "-o","Calculator"
],
"group": {
"kind": "build",
"isDefault": true
},
"problemMatcher":"$gcc"
}
]
}
But when I hit "run main task" it prompts:
"> Executing task: g++ -g Calculator.cpp -o Calculator <
'g++' is not recognized as an internal or external command,
operable program or batch file.
The terminal process terminated with exit code: 1"
How can I get gcc detected?
I'm using VS Code with Windows 10 machine BTW.
If you have not added the folder path to windows, try that first.
If that still does not work try adding the full path in "task.json" instead of just g++.
Something like this:
C:/MinGW/bin/g++

I just have a quick question:
EDIT: This is run under Ubuntu 20.04 WSL2 using Visual Studio Code.
So I am debugging a kernel for gdb and the symbol files require that GDB is launched in the project directory, but the problem is GDB keep launching in the location of the program:
-exec pwd
Working directory /home/user/project-directory/obj/kern
I need GDB to stay in the project-directory:/home/user/project-directory
In the VSCode launch.json file, I made a workaround by adding a custom launch setup as shown below:
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug Kernel",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceRoot}/obj/kern/kernel",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"printCalls": true,
"showDevDebugOutput": true,
"setupCommands": [
{
"description": "Change back to the workspace folder",
"text": "cd ${workspaceRoot}",
"ignoreFailures": true
},
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],
// "preLaunchTask": "Launch Qemu (no graphic)",
"miDebuggerPath": "/usr/bin/gdb",
"miDebuggerArgs": "",
"targetArchitecture": "x86_64",
"customLaunchSetupCommands": [
{
"text": "target remote localhost:1234",
"description": "Connect to QEMU remote debugger"
},
{
"text": "symbol-file obj/kern/kernel",
"description": "Get kernel symbols"
},
// {
// "text": "set architecture i8086",
// "description": "Sets the current architecture"
// }
],
"avoidWindowsConsoleRedirection": true
}
]
}
The ${workspaceFolder} and ${workspaceRoot} are located in the project's directory, but without the setup to change back into the workspace folder, it won't work. Any tips would be appreciated!
I'm creating a VScode theme.
My project structure is very simple:
mytheme
|_ .vscode
|_ launch.json
|_ assets
|_ ...some png files
|_ themes
|_ mytheme.json
.vscodeignore
package.json
README.md
The mytheme.json is something like this:
{
"name": "mytheme",
"type": "dark",
"colors": {
//////////////////////////////
// CONTRAST COLOR
// The contrast colors are typically only set for high contrast themes.
// If set, they add an additional border around items across the UI to increase the contrast.
//////////////////////////////
// An extra border around active elements to separate them from others for greater contrast.
"contrastActiveBorder": "#fa0000",
// "contrastActiveBorder": "#FFFFFF00",
// An extra border around elements to separate them from others for greater contrast.
//"contrastBorder": "#fa0000",
//////////////////////////////
// BASE COLORS
//////////////////////////////
// Overall border color for focused elements. This color is only used if not overridden by a component.
"focusBorder": "#9B6DFF66",
// Overall foreground color. This color is only used if not overridden by a component.
"foreground": "#D9E0E8",
// Shadow color of widgets such as Find/Replace inside the editor.
"widget.shadow": "#1F2330",
// Background color of text selections in the workbench (for input fields or text areas, does not apply to selections within the editor and the terminal).
"selection.background": "#9B6DFF99",
// Foreground color for description text providing additional information, for example for a label.
"descriptionForeground": "#808182",
// Overall foreground color for error messages (this color is only used if not overridden by a component).
"errorForeground": "#9B6DFF",
// The default color for icons in the workbench.
"icon.foreground": "#D9E0E8",
...
}
}
and my package.json:
{
"name": "mytheme",
"version": "1.0.0",
"publisher": "...",
"icon": "assets/logo_square.png",
"galleryBanner": {
"color": "#1F2330",
"theme": "dark"
},
"engines": {
"vscode": "^1.42.0"
},
"displayName": "Mytheme",
"description": "...",
"categories": [
"Themes"
],
"contributes": {
"themes": [
{
"label": "Mytheme",
"uiTheme": "vs-dark",
"path": "./themes/mytheme.json"
}
]
},
"repository": {
"type": "git",
"URL": "....git"
},
"bugs": {
"URL": "..."
},
"author": {
"name": "...",
"email": "...",
},
"license": "MIT",
"keywords": [
"vscode",
"theme",
"color-theme",
"dark"
],
"private": false
}
Very simple. It works like a charm. But there is a big problem: it's very difficult to maintain because mytheme.json is a very very long file and it's a simple .json and If I want to modify for example the accent color, I need to do a find and replace.
I would like to develop my theme in a smarter way, I would like to use variables, save my N colors in variables and use them.
json format doesn't support variables so I ask you how can I do that?
I don't know if there is a standard way to do that, I imagine developing in js and then running a script that transforms my work into a valid json but how?
For example:
const PURPLE = "#9B6DFF"
const baseColors = {
...
errorForeground: PURPLE,
...
}
return ...
I didn't find a guide to follow.
Following the suggestion of #rioV8, I created these files:
.vscode/launch.json:
{
"version": "0.2.0",
"configurations": [
{
"type": "extensionHost",
"request": "launch",
"name": "Launch Extension",
"runtimeExecutable": "${execPath}",
"args": [
"--extensionDevelopmentPath=${workspaceFolder}"
],
"outFiles": [
"${workspaceFolder}/out/**/*.js"
],
"preLaunchTask": "parseToJson",
},
],
}
.vscode/tasks.json:
{
"version": "2.0.0",
"tasks": [
{
"label": "parseToJson",
"command": "tsc",
"type": "shell",
"presentation": {
"reveal": "silent",
"panel": "new"
},
"args": [
"--target",
"ES5",
"--outDir",
"js",
"--sourceMap",
"--watch",
"parse.ts"
],
"problemMatcher": "$tsc"
}
]
}
.vscode/parse.ts:
const PURPLE = "#9B6DFF"
const baseColors = {
errorForeground: PURPLE,
}
// create json
const mytheme = {
"name": "mytheme",
"type": "dark",
"colors": {...baseColors}
}
function createJsonTheme() {
// save to json
const file = new File(mytheme, "../themes/mytheme.json", {
type: "text/plain",
});
}
createJsonTheme()
When I run it, I get:
error TS6053: File 'parse.ts' not found. The file is in the program
because:
Root file specified for compilation
The path seems ok to me, where is The problem?
The createJsonTheme function goal is to create an object to save then in a json file inside themes folder.
Variables won't help. The theme file is a mapping of token values to color values. A theme editor tool could help you to be more productive, but I don't know any.
I solved doing like this:
launch.json:
{
"version": "0.2.0",
"configurations": [
{
"name": "Run Extension",
"type": "extensionHost",
"request": "launch",
"runtimeExecutable": "${execPath}",

],
"preLaunchTask": "npm: build"
},
{
"name": "Run Extension Without Build",
"type": "extensionHost",
"request": "launch",
"runtimeExecutable": "${execPath}",
"args": [
"--extensionDevelopmentPath=${workspaceFolder}"
]
}
]
}
tasks.json:

"tasks": [

"type": "npm",
"script": "start",
"group": {
"kind": "build",

},
{
"type": "npm",
"script": "build",
"group": "build",
"problemMatcher": [],
"label": "npm: build",
"detail": "node src/index.js"
}
]
}
package.json:
...
"scripts": {
"start": "nodemon --watch src src/index.js",
"build": "node src/index.js && mkdir -p build",
"prepublishOnly": "npm run build && vsce publish"
}
...
src/index.js:
const fs = require('fs').promises
const getTheme = require('./theme')
const ohlalaTheme = getTheme({
theme: 'dark',
name: 'Mytheme',
})
// write theme
fs.mkdir('./themes', { recursive: true })
.then(() =>
Promise.all([
fs.writeFile('./themes/mytheme.json', JSON.stringify(ohlalaTheme, null, 2)),
])
)
.catch(() => process.exit(1))
src/theme.js
const { colors } = require('./colors')
function getTheme({ theme, name }) {
const themes = (options) => options[theme]
return {
name: name,
colors: {
focusBorder: colors.green,
},
semanticHighlighting: true,
...
}
}
module.exports = getTheme
src/colors.js:
const colors = {
green: '#......',
}
module.exports = { colors }
I have an issue with launch a cpp project file with vscode, here is my error
launch program {workspace domain}\build\Debug\outDebug does not exist.
and that's true, but i want to know can I add a parameter to my launch.json file or edit it, to work like : if a there is no directory to put the build file into it, so make it!
is it possible to do that ?
here is my launch.json file source
{
"version": "0.2.0",
"configurations": [
{
"name": "C/C++ Runner: Debug Session",
"type": "cppdbg",

May be there is solve.
I am switching to VSCode from MetaEditor to develop for MetaTrader4.
I'm using MetaTrader4 and MetaEditor in Linux via Wine.
(and MetaEditor runs quite terribly in Wine)
I would like to create a task to compile the code, and hopefully return the same error log to VSCode to further debug the code as if I was using MetaEditor.
I've used this post to figure out what CLI command has been used to compile MQL4:
Compiling MQL4 via command line through wine metaeditor.exe
/usr/bin/wine /path/to/MT4/metaeditor.exe /compile:"Z:\path\to\MT4\MQL4\Experts\Foo\Bar_EA.mq4" /include:"Z:\path\to\MT4\MQL4" /log
My issue is that I don't understand and cannot find any resource that explains what the "commands" inside the tasks.json file does or list of available variables. Like "/include:" or "presentation":, ${file}, etc.
So I took some guesses and I pieced it together to look something like this so far:
{
"version": "2.0.0",
"tasks": [
{
"label": "MQL4 Compile",
"type": "shell",
"command": "/usr/bin/wine /.wine/drive_c/Program Files (x86)/FXChoice MetaTrader 4/metaeditor.exe",
"args": [
"/compile:${file}"
]
}
]
}
Its probably not quite right.
I appreciate your help, thank you

When using the "Open Folder" functionality of Visual Studio, the IDE searches for project settings and configurations in a special json file. For CPP projects, this could be CppProperties.json. For CMake projects, this could be CMakeSettings.json.
This json file contains a collection of one or more "configurations," such as "Debug" or "Release". I will use a recent CMake project as an example:
"configurations": [
{
"name": "ARM-Debug",
"generator": "Ninja",
"configurationType": "Debug",
"inheritEnvironments": [
"gcc-arm"
],
"buildRoot": "${env.USERPROFILE}\\CMakeBuilds\\${workspaceHash}\\build\\${name}",
"installRoot": "${env.USERPROFILE}\\CMakeBuilds\\${workspaceHash}\\install\\${name}",
"cmakeCommandArgs": "",
"buildCommandArgs": "-v",
"ctestCommandArgs": "",
"intelliSenseMode": "linux-gcc-arm",
"variables": [
{
"name": "CMAKE_TOOLCHAIN_FILE",
"value": "${workspaceRoot}/cmake/arm-none-eabi-toolchain.cmake"
}
]
},
{
"name": "ARM-Release",
"generator": "Ninja",
"configurationType": "Release",
"inheritEnvironments": [
"gcc-arm"
],
"buildRoot": "${env.USERPROFILE}\\CMakeBuilds\\${workspaceHash}\\build\\${name}",
"installRoot": "${env.USERPROFILE}\\CMakeBuilds\\${workspaceHash}\\install\\${name}",
"cmakeCommandArgs": "",
"buildCommandArgs": "-v",
"ctestCommandArgs": "",
"intelliSenseMode": "linux-gcc-arm",
"variables": [
{
"name": "CMAKE_TOOLCHAIN_FILE",
"value": "${workspaceRoot}/cmake/arm-none-eabi-toolchain.cmake"
}
]
}
As you can see, I have two configurations with nearly identical properties.
My question: is it possible to define these common/shared properties once, in such a way as to allow the configurations to inherit them and avoid repeating myself?
The easier way is to define an environment at global level (outside of any configuration), such as:
{
"environments": [
{
"namespace" : "env",
"varName": "varValue"
}
],
Then you can reuse that wherever you need to, e.g.:
"cmakeCommandArgs": "${env.varName}",
You can also have multiple environments, and reuse them, like this:
{
"environments": [
{
"environment": "env1",
"namespace": "env",
"varName": "varValueEnv1"
},
{
"environment": "env2",
"namespace": "env",
"varName": "varValueEnv2"
}
],
"configurations": [
{
"name": "x64-Release",
"inheritEnvironments": [
"msvc_x64_x64", "env2"
],
"cmakeCommandArgs": "${env.varName}",
.....
}
]
the 'x64-Release' will inherit the variables's value in the environment called "env2" (namespace 'env')
