I am also having this issue on Ubuntu 22.04. Any suggestions?

Hi @kbiesiadecki141,

all of the these deprecations will be resolved in the upcoming ouster-ros release. However, in the meantime you can try adding -DCMAKE_CXX_FLAGS="-Wno-deprecated-declarations -Wno-deprecated" to your build command. In other words:

colcon build ouster_ros --cmake-args -DCMAKE_CXX_FLAGS="-Wno-deprecated-declarations -Wno-deprecated"
