+- It is recommended that you install bison and flex; using yacc
+ and lex may require tweaking of the makefiles. You also need
+ libXpm (see comments in the Notes section below) if you want to have
+ XPM support in wxWidgets (recommended).
+
+- You can now use configure to build wxWidgets and the samples.
+
+ Using configure is the only way to build the library. If it doesn't
+ work for you for whatever reason, please report it (together with detailed
+ information about your platform and the (relevant part of) contents of
+ config.log file) to wx-dev@lists.wxwidgets.org.
+
+
+COMPILING USING CONFIGURE
+=========================
+
+* The simplest case
+-------------------
+
+If you compile wxWidgets on Linux for the first time and don't like to read
+install instructions just do (in the base dir):
+
+> ./configure --with-motif
+> make
+> su <type root password>
+> make install
+> ldconfig
+> exit
+
+Afterwards you can continue with
+
+> make
+> su <type root password>
+> make install
+> ldconfig
+> exit
+
+If you want to remove wxWidgets on Unix you can do this:
+
+> su <type root password>
+> make uninstall
+> ldconfig
+> exit
+
+* The expert case
+-----------------
+
+If you want to do some more serious cross-platform programming with wxWidgets,
+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 wxWidgets - you may also want to create different versions of wxWidgets
+and test them concurrently. Most typically, this would be a version configured
+with --enable-debug and one without.
+
+For building three versions (one GTK, one Motif and a debug version of the GTK
+source) you'd do this:
+
+mkdir buildmotif
+cd buildmotif
+../configure --with-motif
+make
+cd ..
+
+mkdir buildgtk
+cd buildgtk
+../configure --with-gtk
+make
+cd ..
+
+mkdir buildgtkd
+cd buildgtkd
+../configure --with-gtk --enable-debug
+make
+cd ..
+
+Note that since wxWidgets-2.6.0 you can install all those libraries
+concurrently, you just need to pass the appropriate flags when using them.
+
+* The simplest errors
+---------------------
+
+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.
+
+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.
+
+* The simplest program
+----------------------
+
+Now create your super-application myfoo.app and compile anywhere with
+
+g++ myfoo.cpp `wx-config --libs --cxxflags` -o myfoo
+
+* General
+---------
+
+The Unix variants of wxWidgets use GNU configure. If you have problems with
+your make use GNU make instead.
+
+If you have general problems with installation, see the wxWidgets website at
+
+ http://www.wxwidgets.org/
+
+for newest information. If you still don't have any success, please send a bug
+report to one of our mailing lists (see my homepage) INCLUDING A DESCRIPTION OF
+YOUR SYSTEM AND YOUR PROBLEM, SUCH AS YOUR VERSION OF MOTIF, WXMOTIF, WHAT
+DISTRIBUTION YOU USE AND WHAT ERROR WAS REPORTED. I know this has no effect,
+but I tried...
+
+* GUI libraries
+---------------
+
+wxWidgets/Motif requires the Motif library to be installed on your system. As
+an alternative, you may also use the free library "lesstif" which implements
+most of the Motif API without the licence restrictions of Motif.
+
+You can get the newest version of the Lesstif from the lesstif homepage at:
+
+ http://www.lesstif.org/
+
+* Additional libraries
+----------------------
+
+wxWidgets/Motif 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, virtually all Linux distributions have
+correct glibc 2 support.
+
+You can disable thread support by running
+
+./configure --disable-threads
+make
+su <type root password>
+make install
+ldconfig
+exit
+
+* Building wxMotif on OS/2
+--------------------------
+
+Please send comments and question about the OS/2 installation
+to Stefan Neis <Stefan.Neis@t-online.de> and patches to
+the wxWidgets mailing list.
+
+In the following list, the version numbers indicate the configuration that
+was actually used by myself, newer version should cause no problems and
+even older ones are expected to work most of the time.
+
+You'll need OS/2 Warp (4.51) or eCS(1.0), X-Free86/2 (3.3.6 or newer),
+Lesstif (0.92.7 or newer), emx (0.9d fix 4), a Unix like shell (pdksh-5.2.14
+or ash), Autoconf (2.57), GNU file utilities (3.13), GNU text utilities (1.19),
+GNU shell utilites (1.12), m4 (1.4), sed (2.05), grep (2.0), Awk (3.0.3),
+GNU Make (3.75).
+
+Preferably, you should have Posix/2 installed and C(PLUS)_INCLUDE_PATH and
+LIBRARY_PATH set up accordingly, however, wxGTK will even work without it.
+Presence of Posix/2 will be auto-detected.
+
+Open an OS/2 prompt and switch to the directory above.
+Set MAKESHELL or MAKE_SHELL (which one is needed depends on the version of
+make) to a Unix like shell, e.g.
+SET MAKESHELL=ash
+If you have a really deficient version of GNU make, it might even be
+necessary to set SHELL or even COMSPEC to a unix like shell as well.
+Depending on your installation you might want to also set INSTALL, for me
+it tends to try to use the system's tcpip\pcomos\install.exe which causes
+problems, e.g.
+SET INSTALL=<path_to_src_directory>/install-sh -c
+
+Notice that the delivered configure scripts are fully OS/2 aware, so you
+can simply run
+ ash -c "configure --with-motif"
+and make and possibly make install as described above.
+
+To verify Lesstif installation, configure will try to compile a
+sample program that requires X headers/libraries to be either
+available via C_INCLUDE_PATH and LIBRARY_PATH or you need to
+explicitly set CFLAGS prior to running configure.
+
+* Building wxMotif 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 :
+
+CFLAGS="-mips3 -n32"
+CXXFLAGS="-mips3 -n32"
+
+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 64bit 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.
+
+* Building wxMotif on Cygwin
+----------------------------
+
+The normal build instructions should work fine on Cygwin. The one difference
+with Cygwin is that when using the "--enable-shared" configure option (which
+is the default) the API is exported explicitly using __declspec(dllexport)
+rather than all global symbols being available.
+
+This shouldn't make a difference using the library and should be a little
+more efficient. However if an export attribute has been missed somewhere you
+will see linking errors. If this happens then you can work around the
+problem by setting LDFLAGS=-Wl,--export-all-symbols. Please also let us know
+about it on the wx-dev mailing list.
+
+* Create your configuration
+---------------------------
+
+Usage:
+ ./configure [options]
+
+If you want to use system's C and C++ compiler,
+set environment variables CXX and CC as
+
+ % setenv CC cc
+ % setenv CXX CC
+ % ./configure options
+
+to see all the options please use:
+
+ ./configure --help
+
+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 will complain if the system variable OSTYPE has
+not been defined. And Make in some circumstances as well...
+
+
+* 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.
+
+Many of the configure options have been thoroughly tested
+in wxWidgets snapshot 6, but not yet all (ODBC not).
+
+You have to add --with-motif on platforms, where Motif is
+not the default (on Linux, configure will default to GTK).
+
+ --with-motif Use either Motif or Lesstif
+ Configure will look for both.
+
+The following options handle the kind of library you want to build.
+
+ --disable-threads Compile without thread support. Threads
+ support is also required for the
+ socket code to work.
+
+ --disable-shared Do not create shared libraries.
+
+ --enable-monolithic Build wxWidgets as single library instead
+ of as several smaller libraries (which is
+ the default since wxWidgets 2.5.0).
+
+ --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
+ would 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 Equivalent to --enable-debug_info plus
+ --enable-debug-flag.
+
+ --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 wxWidgets' 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.
+
+* Feature Options
+-----------------
+
+Many of the configure options have been thoroughly tested
+in wxWidgets snapshot 6, but not yet all (ODBC not).
+
+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 wxWidgets that
+are not used in your program. The most relevant such features
+are
+
+ --without-libpng Disables PNG image format code.
+
+ --without-libjpeg Disables JPEG image format code.
+
+ --without-odbc Disables ODBC code.
+
+ --without-libtiff Disables TIFF image format code.
+
+ --without-expat Disable XML classes based on Expat parser.
+
+ --disable-threads Disables threads. Will also
+ disable sockets.
+
+ --disable-sockets Disables sockets.
+
+ --disable-dnd Disables Drag'n'Drop.
+
+ --disable-clipboard Disables Clipboard.
+
+ --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.
+
+Apart from disabling certain features you can very often "strip"
+the program of its debugging information resulting in a significant
+reduction in size.
+
+Please see the output of "./configure --help" for comprehensive list
+of all configurable options.
+
+
+* Compiling
+-----------
+
+The following must be done in the base directory (e.g. ~/wxMotif
+or ~/wxWin or whatever)
+
+Now the makefiles are created (by configure) and you can compile
+the library by typing:
+
+ make
+
+make yourself some coffee, as it will take some time. On an old
+Pentium 200 around 40 minutes. During compilation, you may 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 its 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
+
+ make install
+
+You can remove any traces of wxWidgets by typing
+
+ make uninstall
+
+If you want to save disk space by removing unnecessary
+object-files:
+
+ make clean
+
+in the various directories will do the work for you.
+
+* Creating a new Project
+------------------------
+
+1) The first way uses the installed libraries and header files
+automatically using wx-config
+
+g++ myfoo.cpp `wx-config --libs` `wx-config --cxxflags` -o myfoo
+
+Using this way, a make file for the minimal sample would look
+like this
+
+CXX = g++
+
+minimal: minimal.o
+ $(CXX) -o minimal minimal.o `wx-config --libs`
+
+minimal.o: minimal.cpp
+ $(CXX) `wx-config --cxxflags` -c minimal.cpp -o minimal.o
+
+clean:
+ rm -f *.o minimal
+
+If your application uses only some of wxWidgets libraries, you can
+specify required libraries when running wx-config. For example,
+`wx-config --libs=html,core` will only output link command to link
+with libraries required by core GUI classes and wxHTML classes. See
+the manual for more information on the libraries.
+
+2) The other way creates a project within the source code
+directories of wxWidgets. 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.
+
+* Further notes by Julian Smart
+---------------------------------
+
+- You may find the following script useful for compiling wxMotif,
+ especially if installing from zips (which don't preserve file
+ permissions). Make this script executable with the command
+ chmod a+x makewxmotif.
+
+ -------:x-----Cut here-----:x-----
+ # makewxmotif
+ # Sets permissions (in case we extracted wxMotif from zip files)
+ # and makes wxMotif.
+ # Call from top-level wxWidgets directory.
+ # Note that this uses standard (but commonly-used) configure options;
+ # if you're feeling brave, you may wish to compile with threads:
+ # if they're not supported by the target platform, they will be disabled
+ # anyhow
+ # -- Julian Smart
+ chmod a+x configure config.sub config.guess
+ ./configure --with-shared --with-motif --with-debug_flag --with-debug_info --enable-debug --without-threads --without-sockets --without-odbc
+ make
+ -------:x-----Cut here-----:x-----
+
+ This script will build wxMotif using shared libraries. If you want to build
+ a static wxWidgets library, use --disable-shared.
+
+Troubleshooting
+---------------
+
+- Solaris compilation with gcc: if the compiler has problems with the variable
+ argument functions, try putting the gcc fixinclude file paths early in the
+ include path.
+
+- If you operator-related compile errors or strange memory problems
+ (for example in deletion of string arrays), set wxUSE_GLOBAL_MEMORY_OPERATORS
+ and wxUSE_MEMORY_TRACING to 0 in setup.h, and recompile.
