use Boost on VS Code

Question

g++ can't find boost/regex.hpp using this task:

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

I tried also using this arg: "-IC:\\boost\\include\\boost-1_64\\boost"

g++ is installed throug MinGW and i added the bin to PATH enviroment variable

I always used Visual Studio IDE...i'm new to command line stuff

This is how I include path on VS Code:

    "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"

                ],

Before this I included only C:\\boost\\include

And this is the error:

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

compilation terminated. How i can resolve this?

UPDATE 1:

So i included both include and lib folder:

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

            ],

and my compilation task is:

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

now i have this output:

Are you sure about `-I\\C:`? Shouldn't that be just `-IC:\boost\\include\\boost-1_64\\boost`? — user0042, Jul 20 '17 at 16:53
i correct the path with -IC:\\boost\\include\\boost-1_64\\boost but the result is the same — tuttomax, Jul 21 '17 at 07:54
`C:\boost\lib` should be in library paths, not include paths. You should also add the libraries to link with. From the compiler output it looks like the library for Boost.Regex is missing. — Andrey Semashev, Jul 21 '17 at 16:24
VS Code has only includePath and browse.path i don't know if there is something for linking — tuttomax, Jul 22 '17 at 07:55

If C:\boost\include\boost-1_64 is where you installed Boost (i.e. unpacked the source package) then that is the path you should add to your include directories, not C:\boost\include\boost-1_64\boost. The trailing boost directory is present in #include directives in the code.

If you're using a graphical IDE I would expect it to automatically perform escaping the backslash ('\') characters as necessary when it saves the project. Otherwise you might have to escape them manually.

I'm not confident with this command line stuff. I installed boost in this way: unpacked on Downloads folder and then run bootstrap gcc and b2 --prefix=C:\boost --toolset=gcc install so i have include and libs folder in C:\boost – tuttomax Jul 21 '17 at 08:32
`b2 --prefix=C:\boost install` puts headers into `C:\boost\include` and built libraries into `C:\boost\lib`, so those are the paths you should add to your include and library paths. – Andrey Semashev Jul 21 '17 at 08:40
Also, you can surely see where files are installed in the filesystem explorer. – Andrey Semashev Jul 21 '17 at 08:45

As Andrey Semashev said be sure to use the install location of Boost and not the unpacked source location. Standard if you haven't chosen a install prefix while installing Boost this would be C:\Boost on Windows.

For me in Visual Studio Code the only thing i needed to do is open the task.json of my project and at the following lines as followed:

"args":[
"-I",
"C:/Boost/include/boost-1_73" ]

This creates an compiler argument which includes the directory of boost. Then inside the file you should be able to include Boost as following example: #include <boost/lexical_cast.hpp>.

Below the whole tasks.json file:

{
    "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
            }
        }
    ]
}

The `"-I", "C:/Boost/include/boost-1_73"` args in `taks.json` solves my question. — Peng, Oct 06 '22 at 16:26
