* The most simple 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-wine
> make
> su <type root password>
> make install
> ldconfig
> exit
On all variants of Unix except Linux (and maybe except *BSD), shared libraries
are not supported out of the box due to the utter stupidity of libtool, so you'll
have to do this to get shared library support:
> ./configure --with-wine --disable-static --enable-shared
Then you'll have to edit the wrongly created libtool script. There are two
important entries with respect to shared library creation, which are
archive_cmds="\$LD -shared ....
archive_expsym_cmds="\$LD -shared ....
which should be something like
archive_cmds="\$CC -shared ....
archive_expsym_cmds="\$CC -shared ....
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_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 WINE and a debug version of the WINE
source) you'd do this:
md buildmotif
cd buildmotif
../configure --with-motif
make
cd ..
md buildwine
cd buildwine
../configure --with-wine
make
cd ..
md buildwined
cd buildwined
../configure --with-wine --enable-debug_flag
make
cd ..
* The most simple errors
------------------------
wxWINE doesn't work yet as WINE isn't really up to the task yet.
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 optimisation 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
g++ myfoo.cpp `wx-config --libs --cflags` -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, 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 WINE, WXWINE, WHAT DISTRIBUTION
YOU USE AND WHAT ERROR WAS REPORTED. I know this has no effect, but I tried...
* GUI libraries
-----------------------
wxWidgets/WINE requires the WINE library to be installed on your system.
You can get the newest version of the WINE from the WINE homepage at:
http://www.winehq.com
* 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.
Many of the configure options have been thoroughly tested
in wxWidgets snapshot 6, but not yet all (ODBC not).
You must do this by running configure with either of:
--with-wine Use the WINE library
The following options handle the kind of library you want to build.
--enable-threads Compile with thread support. Threads
support is also required for the
socket code to work.
--disable-shared Do not create shared 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-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 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. Not yet. }
--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.
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
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 --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 stick to tmake.
2) The other way creates a project within the source code
directories of wxWidgets. 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
GNU libtool version 1.3
and quite possibly
GNU make
GNU C++
and if you have all this then you probably know enough to
go ahead yourself :-)

In the hope that it will be useful,

Addition notes by Julian Smart, August 2002
===========================================
I've fixed some compile errors, and got as far as
compiling wxWINE, but actually linking a sample will take
further work.
To compile wxWINE, export these variables:
export CPPFLAGS=-I/usr/local/include/wine
export LDFLAGS=-L/usr/local/lib/wine
and configure with:
configure --disable-static --enable-shared --enable-gui \
--with-wine --without-libpng --enable-debug_flag --enable-log \
--enable-debug_info --enable-ole --enable-clipboard --enable-dataobj \
--enable-debug --enable-threads --disable-sockets \
--with-libjpeg --enable-debug_cntxt
Compiling a sample won't work yet because 'winebuild' needs
to be called, and the resuling C file compiled and linked.
Plus, Windows DLLs need to be imported.
Note that the documentation on the WINE web site on using
winebuild is out of date (August 2002) -- the spec file no
longer supports import and type keywords. Instead look at
samples in the WINE 'programs' directory for inspiration
and compile options to use. It's probable that the
wxWINE library will need recompiling with different options.
Any progress on this front will be very welcome.
