Expected Behavior

Suppress all warning messages

Would like to know what argument I can add with the catkin build command to suppress ALL warning messages so that only error messages are printed out

Actual Behavior

A large number of unnecessary warning messages are generated. As a result, it is getting very difficult to find error messages and troubleshoot the code.

When invoking catkin build "orb_slam_3", a large number of depreciation warning is generated by the newest version of Eigen linear algebra library. I am not looking to downgrade to an older Eigen version since the warning messages are depreciation warnings and so far has not comprised functionality of the SLAM pipeline. However, with the large number of warning messages that gets printed out, it requires me to manually scroll through all of it to find the errors. This is very annoying and time consuming.

Is there any way I can suppress all the warning messages when using catkin build command?

Catkin just prints everything cmake/make print to stderr. You can suppress warnings in cmake, either by adding add_compile_options(-w) to your CMakeLists.txt or by running catkin build with -DCMAKE_CXX_FLAGS=-w. -w is the compiler flag that suppresses warnings.
