The prelaunchtask ‘c/c++: clang++ build active file’ terminated with exit code -1.

In the given query, the prelaunchtask ‘c/c++: clang++ build active file’ terminated with exit code -1. This means that the task failed to execute successfully.

Exit code -1 generally indicates an error or problem during the execution of the task. It could be caused by various reasons such as incorrect configurations, missing dependencies, or issues with the task script itself.

To resolve this issue, you can take the following steps:

1. Check the task configuration: Ensure that the task is correctly configured with the appropriate command and arguments. Make sure that the task is referencing the correct compiler (clang++) and that the active file is correctly passed as an argument.
2. Verify dependencies: Ensure that all the required dependencies are installed and properly set up. This includes the compiler (clang++), necessary libraries, and any other tools or packages required for the task.
3. Review task script: If the task has a script associated with it, review the script for any errors or issues. Check for syntax errors, typos, or any invalid commands that could be causing the task to fail.
4. Check for file-specific issues: If the task is specific to a particular file, verify that the file is valid and does not have any errors. Make sure the file has the correct extension (.cpp for C++ files) and that it is not corrupted.
5. Consult documentation or community: If you are still unable to identify the problem, refer to the documentation or community resources related to the specific tool or framework you are using. Other users might have encountered a similar issue and provided solutions or workarounds.

Here is an example of a possible task configuration for building a C++ file using clang++ in VS Code’s tasks.json file:

      
{
   "version": "2.0.0",
   "tasks": [
      {
         "label": "Build with clang++",
         "type": "shell",
         "command": "clang++",
         "args": [
            "${file}", "-o", "${fileDirname}/${fileBasenameNoExtension}"
         ],
         "group": {
            "kind": "build",
            "isDefault": true
         },
         "problemMatcher": [
            "$gcc"
         ]
      }
   ]
}
      
   

This example assumes that you have clang++ installed and properly configured on your system. The task will build the active file and generate an executable with the same name in the same directory.
