Static library and dynamic library creation steps

Static library and dynamic library creation steps-general Linux technology-Linux programming and kernel information. The following is a detailed description. How to Create a static Library:
Compile the Code as the target file:
# Gcc-c liberr. c-o liberr. o
Use the tool ar to create an archive file:
# Ar rcs liberr. a liberr. o
Link the program to liberr. a during program Compilation:
# Gcc errtest. c-o errtest-static-L./-lerr

How to create a dynamic library:
First, compile the target file:
# Gcc-fPIC-g-c liberr. c-o liberr. o
Then link to the Library:
# Gcc-g-shared-Wl,-soname, liberr. so-o liberr. so.1.0.0 liberr. o-lc
Copy the generated dynamic library liberr. so.1.0.0 to the/usr/lib directory:
# Cp liberr. so.1.0.0/usr/lib
Go to the/usr/lib directory and create two linked files:
# Cd/usr/lib
# Ln-s liberr. so.1.0.0 liberr. so.1
# Ln-s liberr. so.1.0.0 liberr. so
Link the compiled program with the dynamic library:
# Gcc errtest. c-o errtest-lerr
