When developing an SO file, is it possible to include an additional SO file?

edit

Yes, it is possible to include an additional SO file when developing an SO file. This can be achieved by linking the additional SO file during the compilation and linking process of the main SO file. The linking process can be performed using a linker command such as ld. The additional SO file must be present in the search path of the linker for it to be included in the final output file. It is also important to ensure that the additional SO file is compatible with the main SO file and that there are no conflicts between their symbols.
