Simple install procedure
========================
- % gzip -cd glib-@GLIB_VERSION@.tar.gz | tar xvf - # unpack the sources
- % cd glib-@GLIB_VERSION@ # change to the toplevel directory
+ % tar xf glib-@GLIB_VERSION@.tar.gz # unpack the sources
+ % cd glib-@GLIB_VERSION@ # change to the toplevel directory
% ./configure # run the `configure' script
% make # build GLIB
Requirements
============
+GLib requires a C90-compliant (but not necessarily C99-compliant) C
+compiler and libc. On UNIX-like systems, it also assumes compliance
+with at least the original 1990 version of POSIX.
+
GLib-2.0 requires pkg-config, which is tool for tracking the
compilation flags needed for libraries. (For each library, a small .pc
text file is installed in a standard location that contains the
http://www.freedesktop.org/software/pkgconfig/
-GNU make (http://www.gnu.org/software/make) is also recommended.
+GNU make (http://www.gnu.org/software/make) is also required.
In order to implement conversions between character sets,
GLib requires an implementation of the standard iconv() routine.
Most modern systems will have a suitable implementation, however

you must install the libiconv library. This can be found at:

If your system has an iconv implementation but you want to use

-The Nitty-Gritty
-================
-
-The 'configure' script can be given a number of options to enable
-and disable various features. For a complete list, type:
-
- ./configure --help
-
-A few of the more important ones:
-
-* --prefix=PREFIX install architecture-independent files in PREFIX
- [ Defaults to /usr/local ]
-
-* --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [ Defaults to the value given to --prefix ]
-
-* --enable-gc-friendly When enabled all memory freed by the application,
- but retained by GLib for performance reasons
- is set to zero, thus making deployed garbage
- collection or memory profiling tools detect
- unlinked memory correctly. This will make GLib
- slightly slower.
- [ Disabled by default ]
+Support for extended attributes and SELinux in GIO requires
+libattr and libselinux.
-* --disable-threads Do not compile GLib to be multi thread safe. GLib
- will be slightly faster then. This is however not
- recommended, as many programs rely on GLib being
- multi thread safe.
- [ Enabled by default ]
+Some of the mimetype-related functionality in GIO requires the
+update-mime-database and update-desktop-database utilities, which
+are part of shared-mime-info and desktop-file-utils, respectively.
-* --with-threads=[none/posix/dce/solaris/win32] Specify a thread
- implementation to use.
- * 'posix' and 'dce' can be used interchangeable
- to mean the different versions of posix
- threads. configure tries to find out, which
- one is installed.
- * 'solaris' uses the native Solaris thread
- implementation.
- * 'none' means that GLib will be thread safe,
- but does not have a default thread
- implementation. This has to be supplied to
- g_thread_init() by the programmer.
- [ Determined by configure by default ]
+GObject uses libffi to implement generic marshalling functionality.
-Options can be given to the compiler and linker by setting
-environment variables before running configure. A few of the more
-important ones:
-
- CC : The C compiler to use
- CPPFLAGS : Flags for the C preprocesser such as -I and -D
- CFLAGS : C compiler flags
+The Nitty-Gritty
+================
-The most important use of this is to set the
-optimization/debugging flags. For instance, to compile with no
-debugging information at all, run configure as:

Installation directories
if you have a version in $prefix/include, this is out of date
and should be deleted.

+.pc files for the various libraries are installed in
$exec_prefix/lib/pkgconfig to provide information when compiling
-other packages that depend on GTK+. If you set PKG_CONFIG_PATH
-so that it points to this directory, then you can get the
+other packages that depend on GLib. If you set PKG_CONFIG_PATH
+so that it points to this directory, then you can get the
correct include flags and library flags for compiling a GLib
application with:
