带有Visual Studio Code的FLTK库

问题描述

我正在尝试从“编程原理和实践”中为第12章安装FLTK库，但是无法识别build命令。我该怎么办？谢谢！

make : The term 'make' is not recognized as the name of a cmdlet,function,script file,or operable program. Check the spelling of the name,or if a path

解决方法

您尚未指定要使用的Visual Studio版本。

转到IDE目录，查找您的Visual Studio版本，然后查找fltk解决方案。在Visual Studio中启动解决方案。
默认情况下，每当您从发行版启动FLTK解决方案时，解决方案配置均为Debug Cairo。将此更改为Debug或Release
检查启动项目-应该是一个名为Demo的项目。
开始构建-它也应该构建所有测试可执行文件。

我通常对Makefile感到更满意，因此我将VS Code设置为在项目中使用Makefile。安装FLTK之后，我已经完成了以下步骤。

我创建一个包含所有源文件，标头等的目录。假设我有一个FLTK_ex文件夹，其中包含hello.cpp及其Makefile
我打开VS Code，然后打开File->Open，然后选择文件夹FLTK_ex
从Terminal菜单中，选择Configure Default Build Task...：在出现的菜单中，依次选择Create tasks.json file from template和Others

出现默认的json文件，我将其修改为

{
"version": "2.0.0","tasks": [
    {
        "label": "Build","type": "shell","command": "Make","problemMatcher": [],"group": {
            "kind": "build","isDefault": true
        }
    }
]

}

要进行编译，请转到Terminal菜单并选择Run Build Task...
要运行该程序，请在Run菜单中选择Run without debugging，C++

出现launch.json文件：将其修改为（其中myprogram是可执行文件的名称）

 {

 "version": "0.2.0","configurations": [
    {
        "name": "(lldb) Launch","type": "cppdbg","request": "launch","program": "${workspaceFolder}/myprogram","args": [],"stopAtEntry": false,"cwd": "${workspaceFolder}","environment": [],"externalConsole": false,"MIMode": "lldb"
    }
    ]
}

要有效地运行该程序，请在Run菜单中再次选择Run without debugging。

我有FLTK 1.3.5，macOS Catalina 10.15.5，clang版本11.0.3，VS代码1.47。

为了在VS Code中使用FLTK，我只是遵循了Readme.OSX.txt中的说明来简单地安装FLTK库，对于Windows系统也有一个类似的文件（README.MSWindows.txt）。

为Makefile编写FLTK的准则是here，如果您需要对Makefile的更多见解，可以找到完整的指南here或简短的介绍here。
