!!! When sending bug reports tell us what version of wxWindows you are
|
|
using (including the beta) and what compiler on what system. One
|
|
example: wxMotif 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 --with-motif
|
|
make
|
|
su <type root password>
|
|
make install
|
|
ldconfig
|
|
exit
|
|
|
|
On all other Unices (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 instead:
|
|
|
|
./configure --enable-static --disable-shared
|
|
make
|
|
su <type root password>
|
|
make install
|
|
ldconfig
|
|
exit
|
|
|
|
You may also want to try to edit the wrongly created libtool script
|
|
in your build directory, if you need shared libraries on Unix. The
|
|
wrong entries are something like
|
|
archive_cmds="\$LD -shared ....
|
|
archive_expsym_cmds="\$LD -shared ....
|
|
which should be something like
|
|
archive_cmds="\$CC -shared ....
|
|
archive_expsym_cmds="\$CC -shared ....
|
|
|
|
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
|
|
------------------------
|
|
|
|
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
|
|
|
|
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/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
|
|
-----------------------
|
|
|
|
wxWindows/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, 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.
|
|
|
|
* 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.
|
|
|
|
* 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 confiugre options have been thoroughly tested
|
|
in wxWindows 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 deafult to GTK).
|
|
|
|
--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. 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 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
|
|
-------------------
|
|
|
|
Many of the confiugre options have been thoroughly tested
|
|
in wxWindows 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 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. 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 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
|
|
|
|
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
|
|
GNU libtool version 1.2 (1.3 seems broken)
|
|
|
|
and quite possibly
|
|
|
|
GNU make
|
|
GNU C++
|
|
|
|
and if you have all this then you probably know enough to
|
|
go ahead yourself :-)
