!!! When sending bug reports tell us what version of wxWindows you are
using (including the beta) and what compiler on what system. One
example: wxGTK 2.3.0, egcs 1.1.1, Redhat 6.2 !!!
* The most simple case
-----------------------
If you compile wxWindows on Linux for the first time and don't like to read
install instructions just do (in the base dir):
> ./configure --with-gtk
> 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 wxWindows 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 wxWindows,
such as for GTK and Motif, you can now build two complete libraries and use
them concurretly. 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 local version of the library for that purpose.
For building three versions (one GTK, one Motif and a debug version of the GTK
source) you'd do this:
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 ..
* The most simple errors
------------------------
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.
You get errors during compilation: The reason is that you probably have a broken
compiler, which includes almost everything that is called gcc. If you use gcc 2.8
you have to disable optimsation as the compiler will give up with an internal
compiler error.
If there is just any way for you to use egcs, use egcs. We cannot fix gcc.
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 broken compiler (and its optimisation) such as GCC 2.8.
* The most simple program
-------------------------
Now create your super-application myfoo.app and compile anywhere with
gcc myfoo.cpp `wx-config --libs --cflags` -o myfoo
* 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, read my homepage at
http://wesley.informatik.uni-freiburg.de/~wxxt
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 GTK, WXGTK, WHAT DISTRIBUTION
YOU USE AND WHAT ERROR WAS REPORTED. I know this has no effect, but I tried...
* GUI libraries
-----------------------
wxWindows/GTK requires the GTK+ library to be installed on your system. It has to
be a stable version, preferebly version 1.2.3.
You can get the newest version of the GTK+ from the GTK homepage at:
http://www.gtk.org
We also mirror GTK+ 1.2.3 at my ftp site. You'll find information about downloading
at my homepage.
* Additional libraries
-----------------------
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:
- RedHat 5.1
- Debian 2.0
- Stampede
- DLD 6.0
- SuSE 6.0
You can disable thread support by running
./configure "--disable-threads"
make
su <type root password>
make install
ldconfig
exit
NB: DO NOT COMPILE WXGTK WITH GCC 2.7 AND THREADS, SINCE ALL PROGRAMS WILL CRASH UPON
START-UP! Just always use egcs and be happy.
* 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:
SET CXXFLAGS=-Zmtd -D__ST_MT_ERRNO__
SET CFLAGS=-Zmtd -D__ST_MT_ERRNO__
SET OSTYPE=OS2X
SET COMSPEC=sh
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
configure --with-gtk
as described above.
If you have pthreads library installed, but have a gtk version
which does not yet support threading, you need to explicitly
diable 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.
* 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 :
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.
* Create your configuration
-----------------------------
Usage:
./configure options
If you want to use system's C and C++ compiler,
set environment variables CC and CCC as
% setenv CC cc
% setenv CCC 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.
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:
--without-gtk Don't use the GIMP ToolKit (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.
--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
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 creation of
giving erros 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.
* 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
--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 serialiasation.
--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.
* 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:
make
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
directiry 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
make install
You can remove any traces of wxWindows 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
gcc myfoo.cpp `wx-config --cflags --libs` -o myfoo
Using this way, a make file for the minimal sample would look
like this
CC = gcc
minimal: minimal.o
$(CC) -o minimal minimal.o `wx-config --libs`
minimal.o: minimal.cpp mondrian.xpm
$(CC) `wx-config --cflags` -c minimal.cpp -o minimal.o
clean:
rm -f *.o minimal
This is certain to become the standard way unless we decide
to sitch to tmake.
2) 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.

In the hope that it will be useful,
