Simple install procedure ======================== % gzip -cd glib-1.3.10.tar.gz | tar xvf - # unpack the sources % cd glib-1.3.10 # change to the toplevel directory % ./configure # run the `configure' script % make # build GLIB [ Become root if necessary ] % rm -rf /install-prefix/include/glib.h /install-prefix/include/gmodule.h % make install # install GLIB Requirements ============ 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 many older systems lack an iconv() implementation. On such systems, you must install the libiconv library. This can be found at: http://clisp.cons.org/~haible/packages-libiconv.html If your system has an iconv implementation but you want to use libiconv instead, you can pass the --with-libiconv option to configure. This forces libiconv to be used. Note that if you have libiconv installed in your default include search path (for instance, in /usr/local/), but don't enable it, you will get an error while compiling GTK+ because the iconv.h that libiconv installs hides the system iconv. 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 ] 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 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: CFLAGS=-O2 ./configure # Bourne compatible shells (sh/bash/zsh) or, setenv CFLAGS -O2 ; ./configure # csh and variants Installation directories ======================== The location of the installed files is determined by the --prefix and --exec-prefix options given to configure. There are also more detailed flags to control individual directories. However, the use of these flags is not tested. One particular detail to note, is that the architecture-dependent include file glibconfig.h is installed in: $exec_pref/lib/glib/include/ if you have a version in $prefix/include, this is out of date and should be deleted. A shell script glib-config is created during the configure process, and installed in the bin/ directory ($exec_prefix/bin). This is used to determine the location of glib when building applications. If you move glib after installation, it will be necessary to edit this file.
