This section covers the mechanics of linking your program with Guile on a typical POSIX system.
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, libguile.
As noted in the previous section, <libguile.h> is not in the
default search path for headers. The following command lines give
respectively the C compilation and link flags needed to build programs
using Guile 3.0:
pkg-config guile-3.0 --cflags pkg-config guile-3.0 --libs
