1. Understanding the Error
The error message "ninja: error: loading build.ninja: no such file or directory" indicates that Ninja can't locate the critical build.ninja file required for the build process. Here's how to address this issue:2. Common Causes of the Error
Let's explore the common reasons for this error:- Missing CMake Configuration: Ensure you've used CMake to configure your project before building it with Ninja.
- Wrong Build Directory: Verify that you are in the correct build directory where the build.ninja file is located.
- Build Files Are Missing or Corrupted: If the build.ninja file is missing or damaged, consider re-running CMake to regenerate the build files.
- Build Configuration Errors: Ensure your CMake configuration is correct and that you haven't introduced errors in your CMakeLists.txt files.
- Ninja Not Installed: Install Ninja on your system using a package manager or by downloading it from the official Ninja website.
- Ninja in PATH: Ensure the Ninja executable is in your system's PATH for easy access.
3. Step 1: Ensure C Make Configuration
Begin by configuring your project with CMake. Open your terminal and run the following command:bash
cmake /path/to/your/source/code
This generates the necessary build files, including build.ninja.
4. Step 2: Verify the Build Directory
Navigate to the correct build directory. If you generated the build files in a separate directory, switch to that directory before running Ninja:bash
cd /path/to/your/build/directory
