A library is a file containing several object files, that can be used as a single entity in a linking phase of a program. Normally the library is indexed, so it is easy to find symbols (functions, variables and so on...) in them. For this reason, linking a program whose object files are ordered in libraries is faster than linking a program whose object files are separate on the disk. Also, when using a library, we have fewer files to look for and open, which even further speeds up linking.

Static libraries are just collections of object files that are linked into the program during the linking phase of compilation, and are not relevant during runtime.
Static libraries are commonly named libname.a. The .a suffix refers to archive

dynamic libraries (also called Shared libraries) are lbrararies in which modules can be bound into the executable program at runtime. when the program is started, a program in the system (called a dynamic loader) checks out which shared libraries were linked with the program, loads them to memory, and attaches them to the copy of the program in memory.
Dynamic libraries are commonly named libname.so. The .so suffix refers to shared object.

DESCRIPTION

       The  jocamlmklib  command facilitates the construction of libraries containing both Caml code and C code, and usable both in static linking
       and dynamic linking modes.

OPTIONS

       -h, --help
	      Show summary of options.

       -cclib lib
	      C library passed to jocamlc -a or jocamlopt(1) -a only.

       -ccopt opt
	      C option passed to jocamlc(1) -a or jocamlopt(1) -a only.

       -custom
	      Disable dynamic loading.

       -dllpath dir
	      Add dir to the run-time search path for DLLs.

       -I dir Add dir to the path searched for Caml object files.

       -failsafe
	      Fall back to static linking if DLL construction failed.

       -ldopt opt
	      C option passed to the shared linker only.

       -linkall

       -o name
	      Generated Caml library is named name.cma or name.cmxa.

       -oc name
	      Generated C library is named dllname.so or libname.a.

       -rpath dir
	      Same as -dllpath dir.
