Hi I want to run codeQL on some C/C++ source files. I am getting the following errors when running ./codeql database create mydb --language=cpp

Hi @dmc1778,

Thanks for your question. From ./codeql database create mydb --language=cpp I suspect you are in the directory in which you installed CodeQL and not in the directory which contains your source code. CodeQL should be executed from the directory containing your source code, or you need to explicitly pass this directory to codeql database create using the --source-root option.

If the above doesn't help and still gives you the same error, then CodeQL is not able to automatically figure out how to build your code. The work around this, you can pass the command with which you build your code to CodeQL using the --command option.
