## Compiling GLib Applications on UNIX

To compile a GLib application, you need to tell the compiler where to find the GLib header files and libraries. This is done with the pkg-config utility.

The following interactive shell session demonstrates how pkg-config is used (the actual output on your system may be different):

    $ pkg-config --cflags glib-2.0
     -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
    $ pkg-config --libs glib-2.0
     -L/usr/lib -lm -lglib-2.0

If your application uses modules, threads or GObject features, it must be compiled and linked with the options returned by the following pkg-config invokations:

    $ pkg-config --cflags --libs gmodule-2.0
    $ pkg-config --cflags --libs gthread-2.0
    $ pkg-config --cflags --libs gobject-2.0

The simplest way to compile a program is to use the "backticks" feature of the shell. If you enclose a command in backticks (not single quotes), then its output will be substituted into the command line before execution. So to compile a GLib Hello, World, you would type the following:

    $ cc `pkg-config --cflags --libs glib-2.0` hello.c -o hello
