"×××××× spdlog.cpp.o"can not be used when making a shared object; recompile with -fPIC about ad-rss-lib HOT 3 CLOSED

Hi looks like the spdlog library that the linker is trying to use under /usr/local/lib/libspdlog.a is not compiled with -fPIC flag in your case. When compiling spdlog this flag has to be enabled.
In the colcon configuration
https://github.com/intel/ad-rss-lib/blob/master/colcon.meta
the cmake argument for position independent code is getting activated:
-DCMAKE_POSITION_INDEPENDENT_CODE=ON

So the solution is to recompile the libspdlog.a with the -fPIC compiler flag active.
Most probably you did not build spdlog using colcon. When you compiled it directly using cmake you can just activate the flag with the above cmake definition.

My problem has been solved. Thank you very much!
