How do I specify the location of compile_commands.json?

[abachrach]

I am trying to use codelite with an external project that uses cmake.

I have cmake configured to generate a compile_commands.json file, but can't figure out how to point codelite to the location of that file.

First, codelite searches for an updated compile_commands.json file after the build is over (does not matter if it succeeded or not).
So make sure:

- You have a workspace opened in codelite with all your sources
- Your workspace file (.workspace file) should be on the same directory as the top level CMakeLists.txt file
- Issue a build (I assume its a custom build project that simply invoke 'make' or something similar)
- When the build is done, codelite will pick the compile_commands.json file and will update its 'compilation.db' (located under workspace-path/.codelite/compilation.db)

To confirm that it worked, you can:
- Open the file workspace-path/.codelite/compilation.db (using the DbExplorer plugin and view its content, located under in the workspace view at the far right...)
- Increase codelite's logging from: settings->global editor preferences->misc->log, and change the verbosity to 'Debug', open the file '~/.codelite/codelite.log' or %appdata%\codelite\codelite.log

Last but not least:
Its your first post on the forum, so please make sure you have read the 'HOW TO POST' thread (check my signature) - you need to provide more information

To configure your workspace properly to use your CMake build, see here:

Thanks for the fast response! My confusion came from thinking that I had to manually provide the path.

I normally build from a terminal outside of the IDE, but after I ran a build within codelite, it looks like codelite was able to find it.

I think that it would be good to be able to manually specify the location of the compilation database (with the default value set to the auto-detected location). In my project I have multiple compile_commands.json files for different build configurations, but would only want codelite to use one of them.
