If your team uses cmake to build your projects, you can use it to generate your Understand project. It will add all of the files, setup the correct macro definitions for each file, and setup the correct include files for each file in the project. The advantage of creating an Understand project like this is that the project will be much more accurate than can be created by hand, allowing you to have easier access to all the features of our new strict parser.
In order to use this,
- Navigate to your build directory
- Edit CMakeCache.txt and set CMAKE_EXPORT_COMPILE_COMMANDS to ON.
- Run make again, you’ll see a file called compile_commands.json in your build directory.
- To import into an understand project run the following from the command line (skip the red part for existing projects):
und -db path/to/db.udb create -languages C++ add path/to/build/dir/compile_commands.json settings -c++AddFoundFilesToProject on analyze
Update – On Windows you must use the NMake Makefiles generator. For example:
cmake -G "NMake Makefiles" -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
