ʕ·ᴥ·ʔ Build EAR

Bear is a tool that generates a compilation database for clang tooling.

The JSON compilation database is used in the clang project to provide information on how a single compilation unit is processed. With this, it is easy to re-run the compilation with alternate programs.

Some build system natively supports the generation of JSON compilation database. For projects which does not use such build tool, Bear generates the JSON file during the build process.

How to install

Bear is packaged for many distributions. Check out your package manager. Or build it from source.

How to use

After installation the usage is like this:

bear -- <your-build-command>

The output file called compile_commands.json is saved in the current directory.

For more options you can check the man page or pass --help parameter. Note that if you want to pass parameter to Bear, pass those before the -- sign, everything after that will be the build command.

Please be aware that some package manager still ship our old 2.4.x release. In that case please omit the extra -- sign or consult your local documentation.

For more, read the man pages or wiki of the project, which talks about limitations, known issues and platform specific usage.
