What Happens When You Compile and Link a Program

Linking with Libraries

Linking with Libraries

In addition to matching external references to global definitions in object files, ld matches external references to global definitions in libraries. A library is a file containing object code for subroutines and data that can be used by other programs. For example, the standard C library, libc, contains object code for functions that can be used by C, C++, FORTRAN, and Pascal programs to do input, output, and other standard operations.

Library Naming Conventions

By convention, library names have the form:

libname.suffix

name

is a string of one or more characters that identifies the

 

library.

suffix

is .a if the library is an archive library or .sl if the

 

library is a shared library. suffix is a number, for

 

example .0, .1, and so forth, if library-level versioning

 

is being used.

Typically, library names are referred to without the suffix. For instance, the standard C library is referred to as libc.

Default Libraries

A compiler driver automatically specifies certain default libraries when it invokes ld. For example, cc automatically links in the standard library libc, as shown by the -lcoption to ld in this example:

$ cc -Aa -v main.c func.c

...

/usr/ccs/bin/ld /opt/langtools/lib/crt0.o -u main main.o \ func.o -lc

cc: Entering Link editor.

Similarly, the Series 700/800 FORTRAN compiler automatically links with the libcl (C interface), libisamstub (ISAM file I/O), and libc libraries:
