If you do not join-LTMC in makefile to connect to your own dynamic library libtmc.so, there will be an error during compilation:

Error prompt, the function in the specified library could not be found.

When the-LTMC option is added, the system searches for the corresponding library file, such as a dynamic library or a static library, such as libtmc.so or LIBTMC.A, in a directory such as the default/usr/lib or/lib. If you have a library file with the same name in the same directory (both dynamic and static), such as libtmc.so and LIBTMC.A, the system first chooses to use the dynamic library libtmc.so.
