How do I Integrate with Visual Studio Code (linux)

[mohamedsayed18]

I following the readme to install vcpkg
when I run ./vcpkg integrate install
output

Applied user-wide integration for this vcpkg root.
CMake projects should use: "-DCMAKE_TOOLCHAIN_FILE=/home/mohamed/vcpkg/scripts/buildsystems/vcpkg.cmake"

I tried these commands

mkdir build
cd build
cmake /home/mohamed/vcpkg/toolsrc/ -DCMAKE_TOOLCHAIN_FILE=/home/mohamed/vcpkg/scripts/buildsystems/vcpkg.cmake

the last line of output Build files have been written to: /home/mohamed/vcpkg/build
but when I run the ./vcpkg integrate install again it gives the same error .
I'm totally new to cmake. am I using the right cmakelists.txt which is inside the toolsrc
Environment:

• ubuntu 18.04

Can you compile your project with make after cmake command? the message "Build files have been written to: /home/mohamed/vcpkg/build" means that you have successfully configured it

[mohamedsayed18]

I cd into the build directory and try make
output:

#10297.

@strega-nil Could you please take a look?

Thanks.

[syys96]

I got it! The message
""Applied user-wide integration for this vcpkg root. CMake projects should use:
"DCMAKE_TOOLCHAIN_FILE=/home/mohamed/vcpkg/scripts/buildsystems/vcpkg.cmake"
indicates you have completed the install of vcpkg. It's just a useful information for cmake user. So you don't need to build the vcpkg again, the "./bootstrap-vcpkg.sh" has done it.
Now you can try to install any packages with " vcpkg install foo"

[syys96]

Do't forget to add vcpkg directory to the PATH variable

[mohamedsayed18]

I realized that the "CMake projects should use: "-DCMAKE_TOOLCHAIN_FILE" message is not an error. when I try to #include <box2d/box2d.h> in vscode. I got this error:

fatal error: box2d/box2d.h: No such file or directory
#include <box2d/box2d.h>

even the vscode autocomplete the library when I include it

[mohamedsayed18]

Do't forget to add vcpkg directory to the PATH variable

can you tell me where exactly the PATH variable is it in the settings.json?
sorry, I'm totally new to make and package manager

[syys96]

It's a system variable of linux configured in the file ~/.bashrc, you can open it with vim or other text editor and add the line:
export PATH=/home/mohamed/vcpkg:$PATH
then save it and run source ~/.bashrc to activate it.

[syys96]

I edit the source file in vscode and build in it's inner terminal successfully. But I can't use the cmake configure and cmake build operation in vscode to build the example. It's very strange

[strega-nil]

@syys96 you need to add to your settings.json your CMAKE_TOOLCHAIN_FILE. You can model it on strega-nil/vcpkg-example (ignore the vcpkg.json stuff)

[zipzit]

I'm having essentially the same issue. Do I add my stuff here, or pull a new issue?

$ hostnamectl 
Operating System: Ubuntu 20.04 LTS
Kernel: Linux 5.4.0-31-generic
Architecture: x86-64

I carefully went thru the installation of vcpkg.

$  ./vcpkg integrate install 
Applied user-wide integration for this vcpkg root.
CMake projects should use: "-DCMAKE_TOOLCHAIN_FILE=/home/lbc/vcpkg/scripts/buildsystems/vcpkg.cmake"

$ ./vcpkg list
fmt:x64-linux             6.2.0            Formatting library for C++. It can be used as a ...

$ echo $PATH
/home/lbc/vcpkg:/home/lbc/.nvm/versions/node/v12.16.1/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

For my testing, I'm using FMT
Test code:

#include <fmt/core.h>      <--- total fail, Cannot open source file, C/C++(1696)
int main() {
  fmt::print("The answer is {}.", 42);
}

I'm using VS Code, version 1.45.1 with C/C++ for Visual Studio Code Extension (0.28.1) installed. As I understand it, from this link that Visual Studio Code C/C++ extension May 2018 Update includes Auto-detection of libraries installed by Vcpkg for IntelliSense.

I've tried both sudo and without for ./vcpkg integrate install All the responses indicate everything is whole, yet, its a total fail finding the import in VS code. Any ideas (or tests to run?)

I'm wondering if my use case is right:

• Full functionality of C++
• with modern libraries
• while using VS Code
• in Linux.

Many thanks for the support here...

[syys96]

Can you build the test in terminal instead of vscode? Or do you add the CMAKE_TOOLCHAIN_FILE to setting.json under your workplace?

[syys96]

CMakeLists.txt
cmake_minimum_required(VERSION 3.12)
set(CMAKE_TOOLCHAIN_FILE /home/lbc/vcpkg/scripts/buildsystems/vcpkg.cmake)
project(test_cpp)
find_package(fmt CONFIG REQUIRED)
add_executable(test_cpp main.cpp)
target_link_libraries(test_cpp PRIVATE fmt::fmt fmt::fmt-header-only)

Then you can use cmake and make to build the test, the progress has successfully passed on my machine

[zipzit]

@syys96 You are my hero! That totally nailed it. I had some sloppiness within my CMakeLists.txt file, at the find_package() command and target_link_libraries() command.

I will say, I don't understand the linker line of code target_link_libraries(CmakeVcpkg PRIVATE fmt::fmt fmt::fmt-header-only). What's up with fmt::fmt fmt::fmt-header-only ? Where did that format come from? Is that a standard format, or just some quirky stuff from the fmt library?

Note, I've been trying to really understand how to correctly use C++ in Linux with VS Code, with a real deugger. In fact i created a decent repo on some expected use cases... In fact, would this be a potential start towards creating a decent beginners tutorial on using VCPKG with VS Code?

https://github.com/zipzit/vscode_cpp_projects

I will say, the fmt library is sort of obtuse. That's not a library I would every be likely to use. I'm thinking of adding a simple graphics or charting library via VCPKG would be a nice touch.

any feedback? And syys96, thank you for your assistance here!

[strega-nil]

@zipzit yeah, that's some oddity with the fmt library. Basically, you can use it either "header-only", or compile it separately. Since you're using vcpkg already to take care of that, there's no reason not to just use fmt::fmt.

[zipzit]

I'm looking at the topic question here: "How do I Integrate with Visual Studio Code (linux)"
And for pure virgins its a multipart answer., reference

1. Figure out how to use VScode for C++ (see 1_cpp_helloworld. )
2. Figure out how to use CMake with VScode for C++ (see 2_cmake_helloworld)
3. Figure out how to use vcpkg with VScode with C++ (see 5_cmake_vcpkg )

I'm wondering if it would be appropriate to do a pull request to add this stuff as a VScode how-to for this repo?
