Hi, I had the same problem and I uses this code

gcc -m64 -Wall -I/usr/include/mariadb/server/ -I/usr/include/mariadb/server/private -I. -shared lib_mysqludf_sys.c -o /usr/lib/x86_64-linux-gnu/mariadb19/plugin/lib_mysqludf_sys.so

path /usr/include/mariadb/server/private contains "my_atomic.h" file

I experienced the same problem on Fedora 31, and my resolution was the same as Jeremy-CB's:

gcc -m64 -Wall -I/usr/include/mariadb/server/ -I/usr/include/mariadb/server/private -I. -shared lib_mysqludf_sys.c -o /usr/lib/x86_64-linux-gnu/mariadb19/plugin/lib_mysqludf_sys.so
