Answer
If you see the error message “protoc did not exit cleanly. Review output for more information”, it means that the protoc command encountered some issues while executing. This can happen due to various reasons such as incorrect command usage, missing dependencies, or errors in the input files.
To better understand the problem, you should review the output generated by the protoc command. The output usually provides more specific details about the error, which can help in troubleshooting and resolving the issue.
Let’s look at an example: Suppose you are trying to compile a protobuf file named “example.proto” using the protoc command:
protoc example.proto
If there are any errors in the “example.proto” file, such as syntax errors or missing import statements, the protoc command will fail to execute cleanly. The error message will provide specific information about the problem, allowing you to fix it.
In this case, you need to review the output to identify the exact error (e.g., line number, error message) and then make the necessary changes to the protobuf file. Once the issues are fixed, you can try running the protoc command again.
Remember to also ensure that you have the correct version of protoc installed and any required dependencies are properly installed.
