Hi, You may try to override the system library using the LD_PRELOAD environment variable. So ld will prefer to resolve the missing symbols from your library but not the system one: https://man7.org/linux/man-pages/man8/ld.so.8.html
Also IRRC, setting LD_LIBRARY_PATH to the directory containing the custom library, may force using your library instead of the system one.
