This is an off topic. Is it possible to combine a few shared library files (.so files) without changing source files of the libraries? I am not sure whether it makes sense or not. I have a few shared libraries and mainly use them separately. But sometimes, for the purpose of easy transportation and loading, I would like to combine them together to form a single big .so file. I could do this by combining all relevant source files together and rebuild it. But I wonder whether it is possible to directly combine the .so files. Comments or hints are welcome. The shared libraries are built in a Linux system and used with S+6 and R. Thanks. Paul.
