@aliaksei-bahdanau, thank you for opening this bug. I am investigating and we will definitely fix this for a soon quick patch update 1.9.1. And we will send you a vsix with a fix even before that, to unblock you faster.
I notice that for presets off this still works as before. Maybe it's an acceptable workaround for you until you get a fix.

EDIT2: It works if you define "cmake.copyCompileCommands" or "cmake.mergedCompileCommands".
For presets on, you also need to have this in your configure preset:
"cacheVariables": {
"CMAKE_EXPORT_COMPILE_COMMANDS": true,
}

Hi, I'm not sure if it's related but I have an issue with the "compile active file" action even after applying your workaround (enabling cmake.copyCompileCommands): when running the action, a compile command is pasted in the terminal but not truncated (and not executed). Interestingly, the command is truncated at 1024 characters, which doesn't seem like a coincidence 😄. Is it related to the issue at hand? Should I report a separate issue?

Note that I've never tried this action before today, so I can't say if it was working before v1.9.0.

Nevermind it seems unrelated to this issue and probably out of your control: microsoft/vscode#38137

@stilllman, you are right, this is a VSCode bug and we had users that reported this before. See this closed GitHub issue.
We can still work around this VSCode problem and we have this open issue that we didn't get to address yet.

@aliaksei-bahdanau, a fix for this problem was included in the CMake Tools 1.9.1 release. Upgrade your extension in VSCode and let us know if you encounter any other issues.

main.cpp:

#include <iostream>

int
main(int argc, char* argv[])
{
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

When I run the "CMake: Compile Active File" from the command palette or when I right-click the source file in the CMake outline and choose "Compile File", I get the following in the Output window:

[extension] [4031] cmake.compileFile finished (returned undefined)
