Linux library file. A. So

1.

. O is equivalent to the OBJ file in windows. a. C or. cpp file corresponds to a. o file.
. A is a combination of multiple. O files for static connections, that is, static mode. Multiple. A files can be linked to generate an EXE executable file.
. So is a shared object for dynamic connection. It is similar to Windows DLL and is loaded only when used.

TS: Error while loading shared libraries: libs. so: cannot open shared object file: no such file or directory system cannot find our own libs. so, tell him to modify the variable LD_LIBRARY_PATH.

View the. A structure, find the original file, and use ar-T Yourfile.
