-Installing wxWindows (and what tools to use).
+CONTENTS: Installing wxWindows (and what tools to use).
+
+Installing wxWindows isn't too hard. Each platform has a different method, so we'll look
+at each major platform in turn.
+
+\section{Unix: GTK+ and Motif}\label{installunix}
+
+\subsection{The simplest case}
+
+If you are compile wxWindows on Linux for the first time and don't like to read
+install instructions, just do this in the base directory:
+
+\begin{verbatim}
+ ./configure --with-gtk
+ make
+ su <type root password>
+ make install
+ ldconfig
+ exit
+\end{verbatim}
+
+This is using the GTK+ port. If using the Motif port, type --with-motif instead of --with-gtk.
+
+Afterwards you can continue with:
+
+\begin{verbatim}
+ make
+ su <type root password>
+ make install
+ ldconfig
+ exit
+\end{verbatim}
+
+If you want to remove wxWindows on Unix you can do this:
+
+\begin{verbatim}
+ su <type root password>
+ make uninstall
+ ldconfig
+ exit
+\end{verbatim}
+
+\subsection{The expert case}
+
+If you want to do some more serious cross-platform programming with wxWindows,
+such as for GTK and Motif, you can now build two complete libraries and use
+them concurrently. For this end, you have to create a directory for each build
+of wxWindows - you may also want to create different versions of wxWindows
+and test them concurrently. Most typically, this would be a version configured
+with --enable-debug\_flag and one without. Note, that only one build can currently
+be installed, so you'd have to use a local version of the library for that purpose.
+For building three versions (one for GTK+, one for Motif and a debug GTK+ version) you'd do this:
+
+\begin{verbatim}
+ md buildmotif
+ cd buildmotif
+ ../configure --with-motif
+ make
+ cd ..
+
+ md buildgtk
+ cd buildgtk
+ ../configure --with-gtk
+ make
+ cd ..
+
+ md buildgtkd
+ cd buildgtkd
+ ../configure --with-gtk --enable-debug_flag
+ make
+ cd ..
+\end{verbatim}
+
+\subsection{The simplest errors}
+
+\begin{itemize}\itemsep=0pt
+\item Configure reports, that you don't have GTK 1.2 installed although you are
+very sure you have. Well, you have installed it, but you also have another
+version of the GTK installed, which you may need to remove including other
+versions of glib (and its headers). Also, look for the PATH variable and check
+if it includes the path to the correct gtk-config! The check your LDPATH if it
+points to the correct library. There is no way to compile wxGTK if configure
+doesn't pass this test as all this test does is compile and link a GTK program.
+\item You get errors during compilation: The reason is that you probably have a
+broken compiler. GCC 2.8 and earlier versions and egcs are likely to cause
+problems due to incomplete support for C++ and optimisation bugs. Best to use
+GCC 2.95 or later.
+\item You get immediate segfault when starting any sample or application: This is
+either due to having compiled the library with different flags or options than
+your program - typically you might have the \_\_WXDEBUG\_\_ option set for the
+library but not for your program - or due to using a compiler with optimisation
+bugs.
+\end{itemize}
+
+\subsection{The simplest program}
+
+Now create your super-application myfoo.app and compile anywhere with:
+
+\begin{verbatim}
+ g++ myfoo.cpp `wx-config --libs --cxxflags` -o myfoo
+\end{verbatim}
+
+\wxheading{General}
+
+The Unix variants of wxWindows use GNU configure. If you have problems with your
+make use GNU make instead.
+
+If you have general problems with installation, visit Robert Roebling's homepage at
+
+\begin{verbatim}
+ http://wesley.informatik.uni-freiburg.de/~wxxt
+\end{verbatim}
+
+for the latest information. If you still don't have any success, please send a bug
+report to one of the mailing lists.
+
+\wxheading{Libraries needed}
+
+wxWindows/GTK requires the GTK+ library to be installed on your system. It has to
+be a stable version, preferably version 1.2.3.
+
+You can get the newest version of the GTK+ from the GTK homepage at:
+
+\begin{verbatim}
+ http://www.gtk.org
+\end{verbatim}
+
+wxWindows/Gtk requires a thread library and X libraries known to work with threads.
+This is the case on all commercial Unix-Variants and all Linux-Versions that are
+based on glibc 2 except RedHat 5.0 which is broken in many aspects. As of writing
+this, these Linux distributions have correct glibc 2 support:
+
+\begin{itemize}\itemsep=0pt
+\item RedHat 5.1
+\item Debian 2.0 and 3.0
+\item Stampede
+\item DLD 6.0
+\item SuSE 6.0
+\end{itemize}
+
+You can disable thread support by running
+
+\begin{verbatim}
+./configure --disable-threads
+make
+su <type root password>
+make install
+ldconfig
+exit
+\end{verbatim}
+
+\subsection{Building wxGTK on OS/2}
+
+Please send comments and question about the OS/2 installation
+to Andrea Venturoli <a.ventu@flashnet.it> and patches to
+the wxWindows mailing list.
+
+You'll need OS/2 Warp (4.00FP#6), X-Free86/2 (3.3.3 or newer),
+GTK+ (1.2.5 or newer), emx (0.9d fix 1), flex (2.5.4), yacc (1.8),
+korn shell (5.2.13), Autoconf (2.13), GNU file utilities (3.6),
+GNU text utilities (1.3), GNU shell utilites (1.12), m4 (1.4),
+sed (2.05), grep (2.0), Awk (3.0.3), GNU Make (3.76.1).
+
+Open an OS/2 prompt and switch to the directory above.
+First set some global environment variables we need:
+
+\begin{verbatim}
+ SET CXXFLAGS=-Zmtd -D__ST_MT_ERRNO__
+ SET CFLAGS=-Zmtd -D__ST_MT_ERRNO__
+ SET OSTYPE=OS2X
+ SET COMSPEC=sh
+ \end{verbatim}
+
+Notice you can choose whatever you want, if you don't like OS2X.
+
+Now, run autoconf in the main directory and in the samples, demos
+and utils subdirectory. This will generate the OS/2 specific
+versions of the configure scripts. Now run
+
+\begin{verbatim}
+ configure --with-gtk
+\end{verbatim}
+
+as described above.
+
+If you have pthreads library installed, but have a gtk version
+which does not yet support threading, you need to explicitly
+disable threading by using the option --disable-threads.
+
+Note that configure assumes your flex will generate files named
+"lexyy.c", not "lex.yy.c". If you have a version which does
+generate "lex.yy.c", you need to manually change the generated
+makefile.
+
+\subsection{Building wxGTK on SGI}
+
+Using the SGI native compilers, it is recommended that you
+also set CFLAGS and CXXFLAGS before running configure. These
+should be set to:
+
+\begin{verbatim}
+ CFLAGS="-mips3 -n32"
+ CXXFLAGS="-mips3 -n32"
+\end{verbatim}
+
+This is essential if you want to use the resultant binaries
+on any other machine than the one it was compiled on. If you
+have a 64-bit machine (Octane) you should also do this to ensure
+you don't accidently build the libraries as 64bit (which is
+untested).
+
+The SGI native compiler support has only been tested on Irix 6.5.
+
+\subsection{Create your configuration}
+
+Usage:
+
+\begin{verbatim}
+ ./configure options
+\end{verbatim}
+
+If you want to use system's C and C++ compiler,
+set environment variables CC and CCC as
+
+\begin{verbatim}
+ setenv CC cc
+ setenv CCC CC
+ ./configure options
+\end{verbatim}
+
+to see all the options please use:
+
+\begin{verbatim}
+ ./configure --help
+\end{verbatim}
+
+The basic philosophy is that if you want to use different
+configurations, like a debug and a release version,
+or use the same source tree on different systems,
+you have only to change the environment variable OSTYPE.
+(Sadly this variable is not set by default on some systems
+in some shells - on SGI's for example). So you will have to
+set it there. This variable HAS to be set before starting
+configure, so that it knows which system it tries to
+configure for.
+
+Configure (and sometimes make) will complain if the system variable OSTYPE has
+not been defined.
+
+\subsubsection{General options}
+
+Given below are the commands to change the default behaviour,
+i.e. if it says "--disable-threads" it means that threads
+are enabled by default.
+
+Normally, you won't have to choose a toolkit, because when
+you download wxGTK, it will default to --with-gtk etc. But
+if you use all of our CVS repository you have to choose a
+toolkit. You must do this by running configure with either of:
+
+\begin{verbatim}
+ --without-gtk Don't use the GIMP ToolKit (GTK)
+
+ --with-motif Use either Motif or Lesstif
+ Configure will look for both.
+\end{verbatim}
+
+The following options handle the kind of library you want to build.
+
+\begin{verbatim}
+ --disable-threads Compile without thread support.
+
+ --disable-shared Do not create shared libraries.
+
+ --enable-static Create static libraries.
+
+ --disable-optimise Do not optimise the code. Can
+ sometimes be useful for debugging
+ and is required on some architectures
+ such as Sun with gcc 2.8.X which
+ and otherwise produce segvs.
+
+ --enable-profile Add profiling info to the object
+ files. Currently broken, I think.
+
+ --enable-no_rtti Enable compilation without creation of
+ C++ RTTI information in object files.
+ This will speed-up compilation and reduce
+ binary size.
+
+ --enable-no_exceptions Enable compilation without creation of
+ C++ exception information in object files.
+ This will speed-up compilation and reduce
+ binary size. Also fewer crashes during the
+ actual compilation...
+
+ --enable-no_deps Enable compilation without creation of
+ dependency information.
+
+ --enable-permissive Enable compilation without checking for strict
+ ANSI conformance. Useful to prevent the build
+ dying with errors as soon as you compile with
+ Solaris' ANSI-defying headers.
+
+ --enable-mem_tracing Add built-in memory tracing.
+
+ --enable-dmalloc Use the dmalloc memory debugger.
+ Read more at www.letters.com/dmalloc/
+
+ --enable-debug_info Add debug info to object files and
+ executables for use with debuggers
+ such as gdb (or its many frontends).
+
+ --enable-debug_flag Define __DEBUG__ and __WXDEBUG__ when
+ compiling. This enable wxWindows' very
+ useful internal debugging tricks (such
+ as automatically reporting illegal calls)
+ to work. Note that program and library
+ must be compiled with the same debug
+ options.
+\end{verbatim}
+
+\subsubsection{Feature Options}
+
+When producing an executable that is linked statically with wxGTK
+you'll be surprised at its immense size. This can sometimes be
+drastically reduced by removing features from wxWindows that
+are not used in your program. The most relevant such features
+are
+
+\begin{verbatim}
+ --with-odbc Enables ODBC code. This is disabled
+ by default because iODBC is under the
+ L-GPL license.
+
+ --without-libpng Disables PNG image format code.
+
+ --without-libjpeg Disables JPEG image format code.
+
+ --without-libtiff Disables TIFF image format code.
+
+ --disable-pnm Disables PNM image format code.
+
+ --disable-gif Disables GIF image format code.
+
+ --disable-pcx Disables PCX image format code.
+
+ --disable-resources Disables the use of *.wxr type
+ resources.
+
+ --disable-threads Disables threads. Will also
+ disable sockets.
+
+ --disable-sockets Disables sockets.
+
+ --disable-dnd Disables Drag'n'Drop.
+
+ --disable-clipboard Disables Clipboard.
+
+ --disable-serial Disables object instance serialisation.
+
+ --disable-streams Disables the wxStream classes.
+
+ --disable-file Disables the wxFile class.
+
+ --disable-textfile Disables the wxTextFile class.
+
+ --disable-intl Disables the internationalisation.
+
+ --disable-validators Disables validators.
+
+ --disable-accel Disables accel.
+\end{verbatim}
+
+Apart from disabling certain features you can very often "strip"
+the program of its debugging information resulting in a significant
+reduction in size.
+
+\subsubsection{Compiling}
+
+The following must be done in the base directory (e.g. ~/wxGTK
+or ~/wxWin or whatever)
+
+Now the makefiles are created (by configure) and you can compile
+the library by typing:
+
+\begin{verbatim}
+ make
+\end{verbatim}
+
+make yourself some coffee, as it will take some time. On an old
+386SX possibly two weeks. During compilation, you'll get a few
+warning messages depending in your compiler.
+
+If you want to be more selective, you can change into a specific
+directory and type "make" there.
+
+Then you may install the library and it's header files under
+/usr/local/include/wx and /usr/local/lib respectively. You
+have to log in as root (i.e. run "su" and enter the root
+password) and type
+
+\begin{verbatim}
+ make install
+\end{verbatim}
+
+You can remove any traces of wxWindows by typing
+
+\begin{verbatim}
+ make uninstall
+\end{verbatim}
+
+If you want to save disk space by removing unnecessary
+object-files:
+
+\begin{verbatim}
+ make clean
+\end{verbatim}
+
+in the various directories will do the work for you.
+
+\subsubsection{Creating a new Project}
+
+1\ket The first way uses the installed libraries and header files
+automatically using wx-config
+
+\begin{verbatim}
+g++ myfoo.cpp `wx-config --cxxflags --libs` -o myfoo
+\end{verbatim}
+
+Using this way, a make file for the minimal sample would look
+like this
+
+\begin{verbatim}
+CXX = g++
+
+minimal: minimal.o
+ $(CXX) -o minimal minimal.o `wx-config --libs`
+
+minimal.o: minimal.cpp mondrian.xpm
+ $(CXX) `wx-config --cxxflags` -c minimal.cpp -o minimal.o
+
+clean:
+ rm -f *.o minimal
+\end{verbatim}
+
+This is certain to become the standard way unless we decide
+to stick to tmake.
+
+2\ket The other way creates a project within the source code
+directories of wxWindows. For this endeavour, you'll need
+GNU autoconf version 2.14 and add an entry to your Makefile.in
+to the bottom of the configure.in script and run autoconf
+and configure before you can type make.
