!!! 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 2.1 beta 6, egcs 1.1.1, Redhat 5.0 !!!
* The most simple case
-----------------------
If you compile wxWindows on Unix for the first time and don't
like to read install instructions just do (in the base dir):
./configure
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
ldconfif
exit
* The most simple errors
------------------------
configure reports, that you don't have GTK 1.X installed
although you are certainly sure you have. Well, you have
installed it, but you also have another version of the
GTK installed, which you may need to removed 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 are sorry, but we cannot fix gcc.
You get immediate segfault when starting any sample
or application: This is _always_ 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.
* The most simple program
-------------------------
Now create your super-application myfoo.app and compile anywhere
with
g++ 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 use
GTK 1.0 in connection with wxWindows, but only without Drag'n'Drop.
wxWindows does work with the 1.1.X versions of the GTK+ library.
You can get the newest version of the GTK+ from the GTK homepage
at
http://www.gtk.org
We also mirror GTK+ 1.2.1 at my ftp site soon. 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 AND THREADS, SINCE
ALL PROGRAMS WILL CRASH UPON START-UP! Just always
use egcs and be happy.
* 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
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.
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
-------------------
!! DON'T USE YET !!
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:
--with-gtk 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.
--with-threads Compile with thread support. Threads
support is also required for the
socket code to work.
--without-shared Do not create shared libraries.
--without-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.
--with-profile Add profiling info to the object
files. Currently broken, I think.
--with-mem_tracing Add built-in memory tracing.
--with-dmalloc Use the dmalloc memory debugger.
Read more at www.letters.com/dmalloc/
--with-debug_info Add debug info to object files and
executables for use with debuggers
such as gdb (or its many frontends).
--with-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
-------------------
!! DON'T USE YET !!
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
--without-libpng Disables PNG image format code.
--without-libjpeg Disables JPEG image format code.
--without-odbc Disables ODBC code.
--without-wxresources Disables the use of *.wxr type
resources.
--without-threads Disables threads. Will also
disable sockets.
--without-sockets Disables sockets.
--without-dnd Disables Drag'n'Drop.
--without-clipboard Disables Clipboard.
--without-serial Disables object instance serialiasation.
--without-streams Disables the wxStream classes.
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 week. 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
--------------------------
There are two ways to create your own project:
1) The first way uses the installed libraries and header files
automatically using wx-config
g++ myfoo.cpp `wx-config --libs` `wx-config --cflags` -o myfoo
Using this way, a make file for the minimal sample would look
like this
CC = g++
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
the usual number of GNU tools, at least
GNU automake version 1.4
GNU autoheader version 2.14
GNU autoconf version 2.14
and quite possibly
GNU make
GNU cc
and if you have all this then you probably know enough to
go ahead yourself :-)
** Something about Makefiles
------------------------------
On general principle it should only contain ONE line, which is as follows:
include ../../setup/general/makeapp
this will include all the necessary definitions for creating the applications
the only case where you might want to add another line is the following:
this version of configure also supports creation of source archives of the
application for easy distribution and updates to newer version of wxWindows.
For this purpose all files in the application-directory will be put into
a gziped tar-file in the full notation user/<your application>/*
if you want to include some other files that you want "more visible", like
a README.<yourApp> or a shell script for easy
compilation/installation/distribution, then you have to add a variable
DISTRIBUTE_ADDITIONAL=<your files>
to the Makefile.
So it would look like this:
DISTRIBUTE_ADDITIONAL=README.TheApp
include ../../setup/general/makeapp
As we have already talked about distribution the command to create a
distribution is:
make distrib
NOTE: If you are in the base directory of wxWindows it will create
distribution packages for wxWindows as well as for all packages in the
user directory.
So if you want to create only packages for the files in user,
then go to the directory other and type:
make distrib
or if you only want one application to be created then
enter the specific directory and type there:
make distrib
All the distribution files will be put in the directory
distrib at the base of the wxWindows-tree (where also configure
and template.mak can be found).
** Something about Makefile.in
--------------------------------
As you have already seen with Makefile, configure makes a lot of use
if the include statement in make to keep the Makefiles as simple as
possible.
So basically there are only variables to define and then a include command.
Exception to this rule is if you have special rules for some stuff...
These rules should go AFTER the include statement!!!
so the general header looks like this:
# wxWindows base directory
WXBASEDIR=@WXBASEDIR@
# set the OS type for compilation
OS=@OS@
# compile a library only
RULE=bin
and the general footer will look like this:
# include the definitions now
include ../../../template.mak
the key variable is RULE, which defines what make should create
in this directory.
here are some examples:
RULE description
===========================================================================
bin creates a local binary (for a global binary prefix bin with g)
additional variables needed:
BIN_TARGET this gives the name of your application
BIN_OBJ this gives the object files needed to
link the application
optional variables are:
BIN_SRC this gives the list of c/c++ files for
which dependencies will be checked.
(This can be achieved with: make depend)
BIN_LINK this gives commands for additional
libraries needed to link the application
---------------------------------------------------------------------------
bin2 creates two local binaries (for global binaries prefix bin2 with g)
in addition to the variables specified above you MUST also
provide the same variables with BIN2_ instead of BIN_
---------------------------------------------------------------------------
lib creates a local library (for a global binary prefix bin with g)
additional variables needed:
LIB_TARGET this gives the name of your library
LIB_OBJ this gives the object files needed for
the library to be build.
optional variables are:
LIB_SRC this gives the list of c/c++ files for
which dependencies will be checked.
libbin and libgbin are also possible and will need in addition
the variables from bin
---------------------------------------------------------------------------
gslib is similar to lib, but it creates a shared library if the system
supports it.
additional variables needed:
LIB_MAJOR major number of the shared library
LIB_MINOR minor number of the shared library
---------------------------------------------------------------------------
other additional variables:
ADD_COMPILE define additional includes/defines that
are needed to compile the object files
(if you need to reference some directory
utils - like wxGrid -, then please
reference them with the variables defined
in template.mak - e.g.: $(SRCDIR),$(UTILS),
$(SAMPLES),$(OTHERS))
NEEDED_DEFINES lists all the defines that HAVE to be set in
/include/wx/setup.h to compile correctly.
SRC_DIR lists all directories that are needed to
compile. (i.e: lists all the directories,
where there are source-files.) But it is
also needed to clean an object and for
machines, for which make does not support
VPATH
currently there are the following compiling rules provided:
object files are created for the following file extensions:
.c .cc .cpp
Please have a closer look at the Makefiles in this distribution.
* Platforms configure is working with
---------------------------------------
Please report build succes on any machine. Especially non-
Linux operating systems (which I don't have).
