要注意的重要一点是，您需要告诉VSCode包含路径和编译器标志才能正常工作。

• 第一步：在VSCode中打开目标文件夹。
• 现在您应该在那里有了一个新的隐藏文件夹.vscode。打开它。
• 您要将pkg-config --cflags gtk+-3.0和pkg-config --libs gtk+-3.0的输出应用于它们各自的配置。

进行智能/代码完成工作

• 创建文件.vscode/c_cpp_properties.json。

• 添加以下内容。

  {
      "env": {
          "myDefaultIncludePath": [
              "${workspaceFolder}","${workspaceFolder}/include"
          ],"myCompilerPath": "/usr/local/bin/g++"
      },"configurations": [
          {
              "name": "include paths","intelliSenseMode": "g++-8","includePath": [
  
                  "/usr/include/gtk-3.0","/usr/include/at-spi2-atk/2.0","/usr/include/at-spi-2.0","/usr/include/dbus-1.0","/usr/lib/x86_64-linux-gnu/dbus-1.0/include","/usr/include/gtk-3.0","/usr/include/gio-unix-2.0","/usr/include/cairo","/usr/include/libdrm","/usr/include/pango-1.0","/usr/include/harfbuzz","/usr/include/fribidi","/usr/include/atk-1.0","/usr/include/pixman-1","/usr/include/freetype2","/usr/include/libpng16","/usr/include/gdk-pixbuf-2.0","/usr/include/libmount","/usr/include/blkid","/usr/include/uuid","/usr/include/glib-2.0","/usr/lib/x86_64-linux-gnu/glib-2.0/include"
  
              ],"compilerPath": "/usr/local/bin/g++","cStandard": "c11","cppStandard": "c++17","browse": {
                  "path": [
                      "${workspaceFolder}"
                  ],"limitSymbolsToIncludedHeaders": true,"databaseFilename": ""
              }
          }
      ],"version": 4
  }
  

• 请注意，“ includePath”的内容是pkg-config --cflags gtk+-3.0的输出，没有前导-I且带有双引号和逗号。 您可能必须根据计算机的输出调整值

进行建筑工程

您要在.vscode/tasks.json内创建一个具有以下内容的新任务：

    {
      "type": "shell","label": "gcc debug build active file - with GTK","command": "/usr/bin/gcc","args": [          
          "-g","-pthread","-I/usr/include/gtk-3.0","-I/usr/include/at-spi2-atk/2.0","-I/usr/include/at-spi-2.0","-I/usr/include/dbus-1.0","-I/usr/lib/x86_64-linux-gnu/dbus-1.0/include","-I/usr/include/gio-unix-2.0","-I/usr/include/cairo","-I/usr/include/libdrm","-I/usr/include/pango-1.0","-I/usr/include/harfbuzz","-I/usr/include/fribidi","-I/usr/include/atk-1.0","-I/usr/include/pixman-1","-I/usr/include/freetype2","-I/usr/include/libpng16","-I/usr/include/gdk-pixbuf-2.0","-I/usr/include/libmount","-I/usr/include/blkid","-I/usr/include/uuid","-I/usr/include/glib-2.0","-I/usr/lib/x86_64-linux-gnu/glib-2.0/include","${file}","-lgtk-3","-lgdk-3","-lpangocairo-1.0","-lpango-1.0","-latk-1.0","-lcairo-gobject","-lcairo","-lgdk_pixbuf-2.0","-lgio-2.0","-lgobject-2.0","-lglib-2.0","-o","${fileDirname}/${fileBasenameNoExtension}"
      ],"options": {
          "cwd": "/usr/bin"
      },"problemMatcher": [
          "$gcc"
      ],"group": {
          "kind": "build","isDefault": true
      }
    } 

• 请注意args中另外两个缩进部分。
• 最上面的是pkg-config --cflags gtk+-3.0的输出。 （不过这次是-I s。）
• 底部是pkg-config --libs gtk+-3.0的输出（加引号和逗号）
• 您可能还需要根据计算机上命令的实际输出来调整这些值

进行调试工作

您要在.vscode/launch.json文件中创建一个新的配置。在我的设置中，vscode一直使用错误的配置，因此我删除了其他配置。以下是该文件的全部内容，只有一种配置。

      "version": "0.2.0","configurations": [

          {

                      "description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true
                  }
              ],"preLaunchTask": "","miDebuggerPath": "/usr/bin/gdb"
          }
      ]
    }
