.TH guile-config 1 "26 May 2008"

.SH NAME

guile-config \- a tool designed to help guile users to get guile

 configuration information 

.SH SYNOPSIS

/usr/bin/guile-config [OPTIONS]

.SH DESCRIPTION

On most systems, you should not need to tell the compiler and linker

explicitly where they can find `libguile.h' and `libguile'.  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

additional `-I' or `-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.

.SH OPTIONS

.I guile-config link

Print the linker command-line flags necessary to link against libguile, and

 any other libraries it requires.

.I guile-config compile

Print C compiler flags for compiling code that uses Guile. This includes

any `-I' flags needed to find Guile's header files.

.I guile-config info [VAR]

Display the value of the Makefile variable VAR used when Guile was built. 

If VAR is omitted, display all Makefile variables. Use this command to find 

out where Guile was installed, where it will look for Scheme code at run-time,

and so on.

.SH EXAMPLES

You can use guile-config for a Scheme program:

.LP

    (use-modules (scripts guile-config))

    (guile-config . args)       => string

    (guile-config/split . args) => list of strings

.LP

ARGS is one of the "commands" above, such as "info" or "compile",

followed by an additional optional specifier.  Either element of

ARGS can be a symbol or a string.  For example, here are two sets

of equivalent invocations:

    (guile-config 'info 'pkgdatadir) 

    (guile-config 'info "pkgdatadir") 

    (guile-config "info" 'pkgdatadir)

    (guile-config "info" "pkgdatadir")

.LP	

    (guile-config 'compile)

    (guile-config "compile")

These procedures basically capture the output as if guile-config

were invoked as a command from the shell.  The former discards

the final newline.  The latter additionally discards whitespace,

and always returns a list (sometimes of length 1).

Behavior is undefined for null ARGS or unrecognized commands.
