1 Simple install procedure
2 ========================
4 % gzip -cd glib-@GLIB_VERSION@.tar.gz | tar xvf - # unpack the sources
5 % cd glib-@GLIB_VERSION@ # change to the toplevel directory
6 % ./configure # run the `configure' script
9 [ Become root if necessary ]
10 % rm -rf /install-prefix/include/glib.h /install-prefix/include/gmodule.h
11 % make install # install GLIB
16 GLib-2.0 requires pkg-config, which is tool for tracking the
17 compilation flags needed for libraries. (For each library, a small .pc
18 text file is installed in a standard location that contains the
19 compilation flags needed for that library along with version number
20 information.) Information about pkg-config can be found at:
22 http://www.freedesktop.org/software/pkgconfig/
24 GNU make (http://www.gnu.org/software/make) is also recommended.
26 In order to implement conversions between character sets,
27 GLib requires an implementation of the standard iconv() routine.
28 Most modern systems will have a suitable implementation, however
29 many older systems lack an iconv() implementation. On such systems,
30 you must install the libiconv library. This can be found at:
32 http://www.gnu.org/software/libiconv/
34 If your system has an iconv implementation but you want to use
35 libiconv instead, you can pass the --with-libiconv option to
36 configure. This forces libiconv to be used.
38 Note that if you have libiconv installed in your default include
39 search path (for instance, in /usr/local/), but don't enable
40 it, you will get an error while compiling GTK+ because the
41 iconv.h that libiconv installs hides the system iconv.
43 If you are using the native iconv implementation on Solaris
44 instead of libiconv, you'll need to make sure that you have
45 the converters between locale encodings and UTF-8 installed.
46 At a minimum you'll need the SUNWuiu8 package. You probably
47 should also install the SUNWciu8, SUNWhiu8, SUNWjiu8, and
50 The native iconv on Compaq Tru64 doesn't contain support for
51 UTF-8, so you'll need to use GNU libiconv instead. (When
52 using GNU libiconv for GTK+, you'll need to use GNU libiconv
53 for GNU gettext as well.) This probably applies to related
54 operating systems as well.
56 Finally, for message catalog handling, GTK+ requires an implementation
57 of gettext(). If your system doesn't provide this functionality,
58 you should use the libintl library from the GNU gettext package,
61 http://www.gnu.org/software/gettext/
66 The 'configure' script can be given a number of options to enable
67 and disable various features. For a complete list, type:
71 A few of the more important ones:
73 * --prefix=PREFIX install architecture-independent files in PREFIX
74 [ Defaults to /usr/local ]
76 * --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
77 [ Defaults to the value given to --prefix ]
79 * --enable-gc-friendly When enabled all memory freed by the application,
80 but retained by GLib for performance reasons
81 is set to zero, thus making deployed garbage
82 collection or memory profiling tools detect
83 unlinked memory correctly. This will make GLib
85 [ Disabled by default ]
87 * --disable-threads Do not compile GLib to be multi thread safe. GLib
88 will be slightly faster then. This is however not
89 recommended, as many programs rely on GLib being
91 [ Enabled by default ]
93 * --with-threads=[none/posix/dce/solaris/win32] Specify a thread
94 implementation to use.
95 * 'posix' and 'dce' can be used interchangeable
96 to mean the different versions of posix
97 threads. configure tries to find out, which
99 * 'solaris' uses the native Solaris thread
101 * 'none' means that GLib will be thread safe,
102 but does not have a default thread
103 implementation. This has to be supplied to
104 g_thread_init() by the programmer.
105 [ Determined by configure by default ]
107 Options can be given to the compiler and linker by setting
108 environment variables before running configure. A few of the more
111 CC : The C compiler to use
112 CPPFLAGS : Flags for the C preprocesser such as -I and -D
113 CFLAGS : C compiler flags
115 The most important use of this is to set the
116 optimization/debugging flags. For instance, to compile with no
117 debugging information at all, run configure as:
119 CFLAGS=-O2 ./configure # Bourne compatible shells (sh/bash/zsh)
123 setenv CFLAGS -O2 ; ./configure # csh and variants
126 Installation directories
127 ========================
129 The location of the installed files is determined by the --prefix
130 and --exec-prefix options given to configure. There are also more
131 detailed flags to control individual directories. However, the
132 use of these flags is not tested.
134 One particular detail to note, is that the architecture-dependent
135 include file glibconfig.h is installed in:
137 $exec_prefix/lib/glib/include/
139 if you have a version in $prefix/include, this is out of date
140 and should be deleted.
142 .pc files for the various libraries are installed in
143 $exec_prefix/lib/pkgconfig to provide information when compiling
144 other packages that depend on GTK+. If you set PKG_CONFIG_PATH
145 so that it points to this directory, then you can get the
146 correct include flags and library flags for compiling a GLib
149 pkg-config --cflags glib-2.0
150 pkg-config --libs glib-2.0
