将 flycheck 与 compile_commands.json 结合使用

Question

I've looked around at some open question, but I cannot figure out how to use flycheck-clangcheck mode to read the include dirs from the compile_commands.json db.

I currently have a largish c++ project. Almost every file would choke on the first #include <some_package> line, and flycheck would not reveal any other errors.

I ended up finding flycheck-clangcheck , and I setup the package per the README, but I cannot get the program to work.

Now, when I open the project, I do not see the flycheck red underline error, but I do see the following error message:

Error while checking syntax automatically: (file-missing "Opening input file" "No such file or directory" "/compile_commands.json")

I have tried modifying: - flycheck-clangcheck-build-path in dir-locals.el as well as in my global emacs config - flycheck-clangcheck-dbname to point directly to the db path.

Does anyone know how I can easily integrate flycheck with the compile_commands.json db?

flycheck-clangcheck-build-path must be set as a string with double ticks eg "/home/user/project/" . flycheck-clangcheck is not controling variable type.
