在 VS Code 上使用 Boost答案

【问题标题】：use Boost on VS Code在 VS Code 上使用 Boost
【发布时间】：2017-07-20 16:50:51
【问题描述】：

g++ 使用此任务找不到 boost/regex.hpp：

{
            "taskName": "C4B", // Compile for debug with boost
            "command": "g++",
            "args": [
                "-g","${fileBasename}""-o","${fileBasenameNoExtension}"
            ],
            "type": "shell"
        },

我也试过使用这个参数："-IC:\\boost\\include\\boost-1_64\\boost"

g++ 是通过 MinGW 安装的，我将 bin 添加到 PATH 环境变量中

我一直使用 Visual Studio IDE...我是命令行新手

这就是我在 VS Code 中包含路径的方式：

    "includePath": [
                    "C:\\MinGW\\lib\\gcc\\mingw32\\5.3.0\\include\\c++",
                    "C:\\boost\\include\\boost-1_64\\boost"

                ],
    "browse": {
                "path": [
                    "C:\\MinGW\\lib\\gcc\\mingw32\\5.3.0\\include\\c++",
                    "C:\\boost\\include\\boost-1_64\\boost"

                ],

在此之前我只包含C:\\boost\\include

这是错误：

test1.cpp:1:27: fatal error: boost/regex.hpp: No such file or directory

编译终止。我该如何解决这个问题？

更新 1：

所以我同时包含了 include 和 lib 文件夹：

"includePath": [
                "C:\\MinGW\\lib\\gcc\\mingw32\\5.3.0\\include\\c++",
                "C:\\boost\\include",
                "C:\\boost\\lib"

            ],

而我的编译任务是：

{
            "taskName": "C4B", // Compile for debug with boost
            "command": "g++",
            "args": [
                "-g","${fileBasename}","-IC:\\boost\\include\\boost-1_64","-o","${fileBasenameNoExtension}"
            ],
            "type": "shell"
        }

现在我有这个输出：

【问题讨论】：

你确定-I\\C:？那不应该只是-IC:\boost\\include\\boost-1_64\\boost吗？
我用 -IC:\\boost\\include\\boost-1_64\\boost 更正了路径，但结果是一样的
C:\boost\lib 应该在库路径中，而不是包含路径中。您还应该添加要链接的库。从编译器输出来看，Boost.Regex 的库似乎丢失了。
VS Code只有includePath和browse.path 不知道有没有可以链接的东西

标签： c++ boost visual-studio-code

【解决方案1】：

如果 C:\boost\include\boost-1_64 是您安装 Boost 的位置（即解压缩源包），那么这就是您应该添加到包含目录的路径，而不是 C:\boost\include\boost-1_64\boost。尾随 boost 目录存在于代码中的 #include 指令中。

如果您使用的是图形 IDE，我希望它在保存项目时根据需要自动执行转义反斜杠 ('\') 字符。否则你可能不得不手动转义它们。

【讨论】：

我对这个命令行的东西没有信心。我以这种方式安装了 boost：在 Downloads 文件夹中解压，然后运行 bootstrap gcc 和 b2 --prefix=C:\boost --toolset=gcc install 所以我在 C:\boost 中有 include 和 libs 文件夹
b2 --prefix=C:\boost install 将标头放入 C:\boost\include 并将库构建到 C:\boost\lib，因此您应该将这些路径添加到包含和库路径中。
另外，您肯定可以在文件系统资源管理器中看到文件的安装位置。

【解决方案2】：

正如Andrey Semashev 所说，一定要使用Boost 的安装位置，而不是解压后的源位置。如果您在安装 Boost 时没有选择安装前缀，则为标准，这将是 Windows 上的 C:\Boost。

对我来说，在 Visual Studio Code 中，我唯一需要做的就是打开我的项目的 task.json，并在以下几行中打开：

“参数”：[
“-我”，
“C:/Boost/include/boost-1_73” ]

这将创建一个包含 boost 目录的编译器参数。然后在文件中，您应该能够包含 Boost，如下例所示：#include .

在整个 tasks.json 文件下方：

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "shell",
            "label": "C/C++: g++.exe build active file",
            "command": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-posix-seh-rt_v6-rev0\\mingw64\\bin\\g++.exe",
            "args": [
                "-g",
                "${workspaceFolder}\\*.cpp",
                "-o",
                "${fileDirname}\\myProgram.exe",
                "-I",
                "C:/Boost/include/boost-1_73"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}
