You can read a full description of the new schema by checking out our updated documentation.The new template of type cppgdb will be used by default whenever you add a new Linux or WSL debug configuration.All your existing debug configurations (of type cppdbg ) will continue to work as expected.In Visual Studio 2019 version 16.6 Preview 2 we introduced a new debugging template to simplify debugging with gdb.

We heard your feedback that it can be difficult to configure debugging sessions on remote Linux systems or the Windows Subsystem for Linux (WSL). Cache variables do not change after the cache is populated during configure, even when you re-run the configure step.This post has been republished via RSS it originally appeared at: Microsoft Developer Blogs - Feed. Hold on, I'm pretty sure that's not how CMake cache variables work. The currently implemented elseif(MINGW) check is bogus and not doing anyone any good. I have tested this change in my own vcpkg install, and it successfully deduces the MinGW triplet. This is why I ultimately suggested the elseif("$ENV" MATCHES "MINGW") (or similar) fix for vcpkg.cmake, which doesn't depend on those environment variables.

The environment variables VCPKG_DEFAULT_TRIPLET and VCPKG_DEFAULT_HOST_TRIPLET are to control vcpkg tool when it is run directly, e.g.

I think it is important to understand that the initial triplet needs to be made permanent (by a CMake cache variable) to avoid messing up the build by accident, after changing the environment variable for another build, or after forgetting to set it after login. This documentation section also shows how users might use the environment variable to set the CMake variable. The CMake cache variable VCPKG_TARGET_TRIPLET is to control the target triplet when running CMake with the vcpkg toolchain. The environment variables VCPKG_DEFAULT_TRIPLET and VCPKG_DEFAULT_HOST_TRIPLET are to control vcpkg tool when it is run directly, e.g. Let's take a step back and look at the documentation: This log file is conclusive proof that vcpkg.cmake is not using the environment variables to inform triplet determination, and is therefore failing in a MinGW64 MSYS2 environment configured per Here, look, I've reproduced it purely on the command line: This will ensure the right dependencies for your project's triplet. vcpkg.cmake does use the environment variables as expected, but it does not see the variable value you expect it to see.

In the end, I think this is a VS Code context problem. instructions affect the shell session only, and everything which is started within that session. As mentioned in the "additional context" section in my issue report, however, I confirmed via inspection and modification of CMakeCache.txt that the problem is the incorrect triplet determination by vcpkg.cmake.Įnsure that vscode uses the same values of the environment variables. It's not my fault that vcpkg.cmake doesn't log the triplet determination anywhere. That completely misses the point of the issue report, which is that the vcpkg.cmake toolchain file does not pick 圆4-mingw-dynamic as the triplet when invoked in a MinGW64 MSYS environment that has been configured per vcpkg instructions. I was able to prove that VCPKG_TARGET_TRIPLET:STRING=圆4-windows is the problem by manually changing the cache file setting to VCPKG_TARGET_TRIPLET:STRING=圆4-mingw-dynamic.

create CMake project with libtcod dependency, per libtcod package instructionsĬMake configure succeeds in finding and configuring libtcod import target.edit vscode cmake-tools config to use vcpkg toolchain file.set environment variables as mentioned above.clone+install vcpkg into MSYS2 /opt/vcpkg, per instructions at.Compiler: MinGW64 GCC (Rev10, Built by MSYS2 project) 11.2.0.This should also be mentioned in the article at because as written, those instructions don't get you to a working environment. The toolchain file should honor the environment variable setting! Having to set and environment variable and muck around with overriding CMake variables is terrible. Having done this, the vcpkg/scripts/buildsystems/vcpkg.cmake toolchain file still internally determines a triplet of 圆4-windows which it stores in my CMakeCache.txt like so: //Vcpkg target triplet (ex. Documentation for using vcpkg with MinGW at says to define the following environment variables to point it to the correct triplet for the compiler: export VCPKG_DEFAULT_TRIPLET=圆4-mingw-dynamicĮxport VCPKG_DEFAULT_HOST_TRIPLET=圆4-mingw-dynamic
