Standardize on using sample.rc and sample icon in all the samples, it was confusing that some of them used it and other didn't, without any apparent logic. Remove the now unnecessary icon files, including the dialogs sample icon which seemed to be corrupted (this closes #11146). Also replace multiple OS/2 resource files with a single one in the sample directory. The OS/2 projects/makefiles would need to be updated to use them. Remove dialogs sample icon. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@64645 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

wxWidgets for GTK+ installation
|
|
-------------------------------
|
|
|
|
IMPORTANT NOTE:
|
|
|
|
If you experience problems installing, please re-read these
|
|
instructions and other related files (todo.txt, bugs.txt and
|
|
osname.txt for your platform if it exists) carefully before
|
|
mailing wxwin-users or the author. Preferably, try to fix the
|
|
problem first and then send a patch to the author.
|
|
|
|
When sending bug reports tell us what version of wxWidgets you are
|
|
using (including the beta) and what compiler on what system. One
|
|
example: wxGTK 2.8.0, gcc 3.4.5, Fedora Core 4
|
|
|
|
* 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):
|
|
|
|
> mkdir buildgtk
|
|
> cd buildgtk
|
|
> ../configure --with-gtk
|
|
> make
|
|
> su <type root password>
|
|
> make install
|
|
> ldconfig
|
|
[if you get "ldconfig: command not found", try using "/sbin/ldconfig"]
|
|
|
|
If you don't do the 'make install' part, you can still use the libraries from
|
|
the buildgtk directory, but they may not be available to other users.
|
|
|
|
If you want to remove wxWidgets on Unix you can do this:
|
|
|
|
> su <type root password>
|
|
> make uninstall
|
|
> ldconfig
|
|
|
|
Note that by default, GTK+ 2.X is used. GTK+ 1.2 can be specified
|
|
with --with-gtk=1.
|
|
|
|
* 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. To do this, create a separate 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 you can install all those libraries concurrently, you just need to
|
|
pass the appropriate flags when using them.
|
|
|
|
* The simplest errors
|
|
---------------------
|
|
|
|
For any configure errors: please look at config.log file which was generated
|
|
during configure run, it usually contains some useful information.
|
|
|
|
configure reports, that you don't have GTK+ 1.2/2.0 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). Or maybe you installed it in a non-default
|
|
location and configure can't find it there, so please check that your PATH
|
|
variable includes the path to the correct gtk-config/pkg-config. Also check
|
|
that your LD_LIBRARY_PATH or equivalent variable contains the path to GTK+
|
|
libraries if they were installed in a non-default location.
|
|
|
|
You get errors from make: please use GNU make instead of the native make
|
|
program. Currently wxWidgets can be built only with GNU make, BSD make and
|
|
Solaris make. Other versions might work or not (any which don't have VPATH
|
|
support definitely won't).
|
|
|
|
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.cpp and compile anywhere with
|
|
|
|
g++ myfoo.cpp `wx-config --libs --cxxflags` -o myfoo
|
|
|
|
* GUI libraries
|
|
---------------
|
|
|
|
wxWidgets/GTK+ requires the GTK+ library to be installed on your system. It has
|
|
to be a stable version, preferably GTK+ 2.x.y, where x is an even number.
|
|
GTK+ version 1.2 is highly discouraged, but if you decide to still use it,
|
|
please use version 1.2.10 (at least 1.2.3 is required, 1.2.7 is strongly recommended).
|
|
|
|
You can get the newest version of the GTK+ from the GTK+ homepage at:
|
|
|
|
http://www.gtk.org
|
|
|
|
We also mirror GTK+ at my ftp site. You'll find information about downloading
|
|
at my homepage.
|
|
|
|
* Additional libraries
|
|
----------------------
|
|
|
|
wxWidgets/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, 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 wxGTK 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),
|
|
GTK+ (1.2.5 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-gtk=1"
|
|
and make and possibly make install as described above.
|
|
|
|
* 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.
|
|
|
|
* Building wxGTK 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 CC and CXX as
|
|
|
|
% setenv CC cc
|
|
% setenv CXX CC
|
|
% ./configure [options]
|
|
|
|
to see all the options please use:
|
|
|
|
./configure --help
|
|
|
|
It is recommended to build wxWidgets in another directory (maybe a
|
|
subdirectory of your wxWidgets installation) as this allows you to
|
|
have multiple configurations (for example, debug and release or GTK
|
|
and Motif) simultaneously.
|
|
|
|
|
|
* 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 SVN repository you have to choose a
|
|
toolkit. You must do this by running configure with either of:
|
|
|
|
--with-gtk=2 Use the GTK+ 2.0. Default.
|
|
--with-gtk=1 Use the GTK+ 1.2.
|
|
--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, but
|
|
build static libraries instead.
|
|
|
|
--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-unicode Enable Unicode support.
|
|
|
|
--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 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.
|
|
|
|
--enable-debug Same as --enable-debug_info and
|
|
--enable-debug_flag together. Unless you have
|
|
some very specific needs, you should use this
|
|
option instead of --enable-debug_info/flag ones
|
|
separately.
|
|
|
|
* 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 wxWidgets 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 which is less liberal than
|
|
wxWidgets license.
|
|
|
|
--without-libpng Disables PNG image format code.
|
|
|
|
--without-libjpeg Disables JPEG image format code.
|
|
|
|
--without-libtiff Disables TIFF image format code.
|
|
|
|
--without-expat Disable XML classes based on Expat parser.
|
|
|
|
--disable-pnm Disables PNM image format code.
|
|
|
|
--disable-gif Disables GIF image format code.
|
|
|
|
--disable-pcx Disables PCX image format code.
|
|
|
|
--disable-iff Disables IFF 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 accelerators support.
|
|
|
|
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. ~/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 --cxxflags --libs` -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.
|
