2022-02-02 01:13:54 -0500	marked best answer	Compiling Cartographer ros failed (cartographer_pbstream) Hi I followed the exact step by step procedure suggested at https://google-cartographer-ros.readt... to build the cartographer package. I came to the build and install step without any problems. when i use this command "catkin_make_isolated --install --use-ninja" i get an error and i couldn't figure it out for days. The error I get is as follows.
