11 How to compile your GLib application
16 <title>Compiling GLib Applications on UNIX</title>
19 To compile a GLib application, you need to tell the compiler where to
20 find the GLib header files and libraries. This is done with the
21 <application>pkg-config</application> utility.
24 The following interactive shell session demonstrates how
25 <application>pkg-config</application> is used (the actual output on
26 your system may be different):
28 $ pkg-config --cflags glib-2.0
29 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
30 $ pkg-config --libs glib-2.0
31 -L/usr/lib -lm -lglib-2.0
35 If your application uses threads or <structname>GObject</structname>
36 features, it must be compiled and linked with the options returned by the
37 following <application>pkg-config</application> invocations:
39 $ pkg-config --cflags --libs gthread-2.0
40 $ pkg-config --cflags --libs gobject-2.0
44 If your application uses modules, it must be compiled and linked with the options
45 returned by one of the following <application>pkg-config</application> invocations:
47 $ pkg-config --cflags --libs gmodule-no-export-2.0
48 $ pkg-config --cflags --libs gmodule-2.0
50 The difference between the two is that gmodule-2.0 adds <option>--export-dynamic</option>
51 to the linker flags, which is often not needed.
54 The simplest way to compile a program is to use the "backticks"
55 feature of the shell. If you enclose a command in backticks
56 (<emphasis>not single quotes</emphasis>), then its output will be
57 substituted into the command line before execution. So to compile
58 a GLib Hello, World, you would type the following:
60 $ cc `pkg-config --cflags --libs glib-2.0` hello.c -o hello
65 If you want to make sure that your program doesn't use any deprecated
66 functions, you can define the preprocessor symbol G_DISABLE_DEPRECATED
67 by using the command line option <literal>-DG_DISABLE_DEPRECATED=1</literal>.
