A static library or statically-linked library is a set of routines, external functions and variables which are resolved in a caller at compile-time and copied into a target application by a compiler, linker, or binder, producing an object file and a stand-alone executable. This executable and the process of compiling it are both known as a static build of the program.

What do 'statically linked' and 'dynamically linked' mean?
I often hear the terms 'statically linked' and 'dynamically linked', often in reference to code written in C, C++ or C#. What are they, what exactly are they talking about, and what are they linking?

Why is statically linking glibc discouraged?
Most of the sources online state that you can statically link glibc, but discourage from doing so; e.g. centos package repo:
The glibc-static package contains the C library static libraries

Why does gcc not implicitly supply the -fPIC flag when compiling static libraries on x86_64
I've had numerous problems compiling shared objects that link statically against static libraries. This problem only shows up on x84_64 platforms. When doing the same compilation work on x86_32 I do not have any problems.
Perhaps this is a OS…

#pragma comment(lib, "xxx.lib") equivalent under Linux?
I have a static library file called libunp.a, I do know I could use gcc -lunp xx to link to the library.
I could use #pragma comment(lib,"xxx.lib") to tell the Microsoft C/C++ compiler to include the library; how could I do it under Linux/GCC?

iOS is it a static or a dynamic framework?
This might sound like a silly question but If you have a thirdParty.framework file, can you tell if it's static or dynamic? I mean, do they look different if you look inside?
