CMake Tools Not Available as C++ Configuration Provider

[KyleFromKitware]

Brief Issue Summary

I'm trying to use CMake Tools as the C++ configuration provider, but it is not available when I go to "C/C++: Change Configuration Provider..."

Expected:

1. Open command palette
2. Select "C/C++: Change Configuration Provider..."
3. "CMake Tools" should be an option

Apparent Behavior:

1. Open command palette
2. Select "C/C++: Change Configuration Provider..."
3. "CMake Tools" is not an option

Platform and Versions

• Operating System: Ubuntu
• CMake Version: 3.20.2
• VSCode Version: 1.55.2
• CMake Tools Extension Version: 1.7.1
• Compiler/Toolchain: GCC 9.3.0

Other Notes/Information

I am using CMakeUserPresets.json, not sure if this is relevant or not.

CMake Tools does not currently register itself until a successful "configure" has happened. We recommend setting cmake.configureOnOpen to true until we make this the default value. Otherwise, you can run the CMake: Configure command and that will start the provider. We're also looking at #1149 and #477 which will help for the "unconfigured" or "configured outside of VS Code" situations.

Thanks. I tried running "CMake: Configure" and then changing the provider, but CMake Tools was still not available.

[bobbrow]

Did the configure fail? I don't know of any other reason why this shouldn't work. Is this on the CMake repo, or some other one?

[KyleFromKitware]

The configure succeeded. I just tried it a second time and was still not able to change the configuration provider.

I am working on the CMake repository, but I'm using /usr/bin/cmake for the configure.

[bobbrow]

Hmm... A fresh clone of Kitware/CMake configured fine for me.

Would you be able to set the cmake.loggingLevel to debug, reload the window, run the "configure" command and then share the CMake Tools logs with me? I think you have my email address if you don't want to share them publicly.

[KyleFromKitware]

Thanks. I emailed you the debug log in private.

@xisui-MSFT, @andreeis, The configuration provider doesn't get registered when presets are active. I traced it to here:

vscode-cmake-tools/src/extension.ts

Line 663 in 4d242c7

if (this._cppToolsAPI && cmt.codeModel && cmt.activeKit) {

There is no active Kit when presets are used, so the provider never registers. This code depends on Kits, so we'll need to update this section to work with either Kits or Presets.

@KyleFromKitware, we have a fix for this problem. Until we release 1.7.3 (soon today or tomorrow) you can try the vsix here: https://github.com/microsoft/vscode-cmake-tools/suites/2718070085/artifacts/59903576.
Uninstall CMake Tools 1.7.2 and run the command "Extensions: Install from VSIX" from the palette.
Let us know if IntelliSense works again.

This fixes it for me. I updated the version in package.json to 1.7.3. We just need to update the changelog and we can release it.
