Node:Linking Programs With Guile, Next:Writing Extensions for Guile, Previous:Guile Scripts, Up:Whirlwind Tour
The Guile interpreter is available as an object library, to be linked into applications using Scheme as a configuration or extension language. This chapter covers the mechanics of linking your program with Guile on a typical POSIX system.
Parts III and IV of this manual describe the C functions Guile provides. Furthermore, any Scheme function described in this manual as a "Primitive" is also callable from C; see Primitives.
The header file
<libguile.h> provides declarations for all of
Guile's functions and constants. You should
#include it at the
head of any C source file that uses identifiers described in this
manual. Once you've compiled your source files, you need to link them
against the Guile object code library,
On most systems, you should not need to tell the compiler and linker
explicitly where they can find
When Guile has been installed in a peculiar way, or when you are on a
peculiar system, things might not be so easy and you might need to pass
-L options to the compiler. Guile
provides the utility program
guile-config to help you find the
right values for these options. You would typically run
guile-config during the configuration phase of your program and
use the obtained information in the Makefile.
