Building wxPython 2.5 for Development and Testing
 | 
						|
=================================================
 | 
						|
 | 
						|
This file describes how I build wxWidgets and wxPython while doing
 | 
						|
development and testing, and is meant to help other people that want
 | 
						|
to do the same thing.  I'll assume that you are using either a CVS
 | 
						|
snapshot from http://wxWidgets.org/snapshots/, a checkout from CVS, or
 | 
						|
one of the released wxPythonSrc-2.5.* tarballs.  I'll also assume that
 | 
						|
you know your way around your system, the compiler, etc. and most
 | 
						|
importantly, that you know what you are doing!  ;-)
 | 
						|
 | 
						|
If you want to also install the version of wxPython you build to be in
 | 
						|
your site-packages dir and be your default version of wxPython, then a
 | 
						|
few additional steps are needed, and you may want to use slightly
 | 
						|
different options.  See the INSTALL_ document for more details.  If
 | 
						|
you only use the instructions in this BUILD_ document file then you
 | 
						|
will end up with a separate installation of wxPython and you can
 | 
						|
switch back and forth between this and the release version that you
 | 
						|
may already have installed.
 | 
						|
 | 
						|
.. _INSTALL: INSTALL.html
 | 
						|
.. _BUILD: BUILD.html
 | 
						|
 | 
						|
If you want to make changes to any of the ``*.i`` files, (SWIG interface
 | 
						|
definition files,) or to regenerate the extension sources or renamer
 | 
						|
modules, then you will need an up to date version of SWIG.  Either get
 | 
						|
and build the current CVS version, or version 1.3.20, and then apply
 | 
						|
the patches in wxPython/SWIG.  See the README.txt in that dir for
 | 
						|
details about each patch and also info about those that may already
 | 
						|
have been applied to the SWIG sources.  If you install this build of
 | 
						|
SWIG to a location that is not on the PATH (so it doesn't interfere
 | 
						|
with an existing SWIG install for example) then you can set a setup.py
 | 
						|
command-line variable named SWIG to be the full path name of the
 | 
						|
executable and the wxPython build will use it.  See below for an
 | 
						|
example.
 | 
						|
 | 
						|
In the text below I'll use WXDIR with environment variable syntax
 | 
						|
(either $WXDIR or %WXDIR%) to refer to the top level directory were
 | 
						|
your wxWidgerts and wxPython sources are located.  It will equate to
 | 
						|
whereever you checked out the wxWidgets module from CVS, or untarred
 | 
						|
the wxPythonSrc tarball to.  You can either substitute the $WXDIR text
 | 
						|
below with your actual dir, or set the value in the environment and
 | 
						|
use it just like you see it below.
 | 
						|
 | 
						|
If you run into what appears to be compatibility issues between
 | 
						|
wxWidgets and wxPython while building wxPython, be sure you are using
 | 
						|
the wxWidgets sources included with the wxPythonSrc tarball or the CVS
 | 
						|
snapshot, and not a previously installed version or a version
 | 
						|
installed from one of the standard wxWidgets installers.  With the
 | 
						|
"unstable" releases (have a odd-numbered minor release value, where
 | 
						|
the APIs are allowed to change) there are often significant
 | 
						|
differences between the W.X.Y release of wxWidgets and the W.X.Y.Z
 | 
						|
release of wxPython.
 | 
						|
 | 
						|
 | 
						|
 | 
						|
Building on Unix-like Systems (e.g. Linux and OS X)
 | 
						|
---------------------------------------------------
 | 
						|
 | 
						|
These platforms are built almost the same way while in development
 | 
						|
so I'll combine the descriptions about their build process here.
 | 
						|
First we will build wxWidgets and install it to an out of the way
 | 
						|
place, then do the same for wxPython.
 | 
						|
 | 
						|
 | 
						|
1. Create a build directory in the main wxWidgets dir, and configure
 | 
						|
   wxWidgets.  If you want to have multiple builds with different
 | 
						|
   configure options, just use different subdirectories.  I normally
 | 
						|
   put the configure command in a script named ".configure" in each
 | 
						|
   build dir so I can easily blow away everything in the build dir and
 | 
						|
   rerun the script without having to remember the options I used
 | 
						|
   before::
 | 
						|
 | 
						|
	 cd $WXDIR
 | 
						|
         mkdir bld
 | 
						|
         cd bld
 | 
						|
         ../configure --prefix=/opt/wx/2.5 \
 | 
						|
                      --with-gtk \
 | 
						|
                      --with-opengl \
 | 
						|
                      --enable-debug \
 | 
						|
                      --enable-geometry \
 | 
						|
                      --enable-sound --with-sdl \
 | 
						|
                      --enable-display \
 | 
						|
                      
 | 
						|
 | 
						|
   On OS X of course you'll want to use --with-mac instead of
 | 
						|
   --with-gtk.  
 | 
						|
 | 
						|
   **NOTE**: Due to a recent change there is a dependency problem in the
 | 
						|
   multilib builds of wxWidgets on OSX, so I have switched to a
 | 
						|
   monolithic build on that platform.  (IOW, all of the core code in
 | 
						|
   one shared library instead of several.)  I would also expect other
 | 
						|
   unix builds to do just fine with a monolithic library, but I havn't
 | 
						|
   tested it in a while so your mileage may vary.  Anyway, to switch
 | 
						|
   to the monolithic build of wxWidgets just add this configure flag::
 | 
						|
 | 
						|
		     --enable-monolithic \
 | 
						|
 | 
						|
   By default GTK2 will be selected if it is on your build system.  To
 | 
						|
   force the use of GTK 1.2.x add this flag::
 | 
						|
 | 
						|
		      --disable-gtk2 \
 | 
						|
 | 
						|
   To make the wxWidgets build be Unicode enabled (strongly
 | 
						|
   recommended if you are building with GTK2) then add::
 | 
						|
                         
 | 
						|
                      --enable-unicode \
 | 
						|
 | 
						|
   Notice that I used a prefix of /opt/wx/2.5.  You can use whatever
 | 
						|
   path you want, such as a path in your HOME dir or even one of the
 | 
						|
   standard prefix paths such as /usr or /usr/local if you like, but
 | 
						|
   using /opt this way lets me easily have multiple versions and ports
 | 
						|
   of wxWidgets "installed" and makes it easy to switch between them,
 | 
						|
   without impacting any versions of wxWidgets that may have been
 | 
						|
   installed via an RPM or whatever.  For the rest of the steps below
 | 
						|
   be sure to also substitute "/opt/wx/2.5" with whatever prefix you
 | 
						|
   choose for your build.
 | 
						|
 | 
						|
   If you want to use the image and zlib libraries included with
 | 
						|
   wxWidgets instead of those already installed on your system, (for
 | 
						|
   example, to reduce dependencies on 3rd party libraries) then you
 | 
						|
   can add these flags to the configure command::
 | 
						|
 | 
						|
                     --with-libjpeg=builtin \
 | 
						|
                     --with-libpng=builtin \
 | 
						|
                     --with-libtiff=builtin \
 | 
						|
                     --with-zlib=builtin \
 | 
						|
 | 
						|
 | 
						|
2. To build and install wxWidgets you could just use the "make"
 | 
						|
   command but there are other libraries besides the main wxWidgets
 | 
						|
   libs that also need to be built so again I make a script to do it
 | 
						|
   all for me so I don't forget anything.  This time it is called
 | 
						|
   ".make" (I use the leading "."  so when I do ``rm -r *`` in my build
 | 
						|
   dir I don't lose my scripts too.)  This is what it looks like::
 | 
						|
 | 
						|
        make $* \
 | 
						|
            && make -C contrib/src/gizmos $* \
 | 
						|
            && make -C contrib/src/ogl CXXFLAGS="-DwxUSE_DEPRECATED=0" $* \
 | 
						|
            && make -C contrib/src/stc $* \
 | 
						|
            && make -C contrib/src/xrc $* 
 | 
						|
   
 | 
						|
   So you just use .make as if it where make, but don't forget to set
 | 
						|
   the execute bit on .make first!::
 | 
						|
 | 
						|
         .make
 | 
						|
         .make install
 | 
						|
 | 
						|
   When it's done you should have an installed set of files under
 | 
						|
   /opt/wx/2.5 containing just wxWidgets.  Now to use this version of
 | 
						|
   wxWidgets you just need to add /opt/wx/2.5/bin to the PATH and set
 | 
						|
   LD_LIBRARY_PATH (or DYLD_LIBRARY_PATH on OS X) to /opt/wx/2.5/lib.
 | 
						|
 | 
						|
 | 
						|
3. I also have a script to help me build wxPython and it is checked in
 | 
						|
   to the CVS as wxWidgets/wxPython/b, but you probably don't want to
 | 
						|
   use it as it's very cryptic and expects that you want to run SWIG,
 | 
						|
   so if you don't have the latest patched up version of SWIG then
 | 
						|
   you'll probably get stuck.  So I'll just give the raw commands
 | 
						|
   instead.
 | 
						|
 | 
						|
   We're not going to install the development version of wxPython with
 | 
						|
   these commands, so it won't impact your already installed version
 | 
						|
   of the latest release.  You'll be able test with this version when
 | 
						|
   you want to, and use the installed release version the rest of the
 | 
						|
   time.  If you want to install the development version please read
 | 
						|
   INSTALL.txt.
 | 
						|
 | 
						|
   If you have more than one version of Python on your system then be
 | 
						|
   sure to use the version of Python that you want to use when running
 | 
						|
   wxPython programs to run the setup.py commands below.  I'll be
 | 
						|
   using python2.3.
 | 
						|
 | 
						|
   Make sure that the first wx-config found on the PATH is the one you
 | 
						|
   installed above, and then change to the $WXDIR/wxPython dir and
 | 
						|
   run the this command::
 | 
						|
 | 
						|
         cd $WXDIR/wxPython
 | 
						|
         python2.3 setup.py build_ext --inplace --debug
 | 
						|
 | 
						|
   If your new wx-config script is not on the PATH, or there is some
 | 
						|
   other version of it found first, then you can add this to the
 | 
						|
   command line to ensure your new one is used instead::
 | 
						|
 | 
						|
         WX_CONFIG=/opt/wx/2.5/bin/wx-config
 | 
						|
 | 
						|
   By default setup.py will assume that you built wxWidgets to use
 | 
						|
   GTK2.  If you built wxWidgets to use GTK 1.2.x then you should add
 | 
						|
   this flag to the command-line::
 | 
						|
 | 
						|
	 WXPORT=gtk2 
 | 
						|
 | 
						|
   If you would like to do a Unicode enabled build (all strings sent
 | 
						|
   to or retruned from wx functions are Unicode objects) and your
 | 
						|
   wxWidgets was built with unicode enabled then add this flag::
 | 
						|
 | 
						|
         UNICODE=1
 | 
						|
 | 
						|
   If you are wanting to have the source files regenerated with swig,
 | 
						|
   then you need to turn on the USE_SWIG flag and optionally tell it
 | 
						|
   where to find the new swig executable, so add these flags::
 | 
						|
 | 
						|
         USE_SWIG=1 SWIG=/opt/swig/bin/swig
 | 
						|
 | 
						|
   If you get errors about being unable to find libGLU, wxGLCanvas
 | 
						|
   being undeclared, or something similar then you can add
 | 
						|
   BUILD_GLCANVAS=0 to the setup.py command line to disable the
 | 
						|
   building of the glcanvas module.
 | 
						|
 | 
						|
   When the setup.py command is done you should have fully populated
 | 
						|
   wxPython and wx packages locally in $WXDIR/wxPython/wxPython and
 | 
						|
   $WXDIR/wxPython/wx, with all the extension modules (``*.so`` files)
 | 
						|
   located in the wx package.
 | 
						|
 | 
						|
 | 
						|
4. To run code with the development version of wxPython, just set the
 | 
						|
   PYTHONPATH to the wxPython dir located in the source tree.  For
 | 
						|
   example::
 | 
						|
 | 
						|
        export LD_LIBRARY_PATH=/opt/wx/2.5/lib
 | 
						|
        export PYTHONPATH=$WXDIR/wxPython
 | 
						|
        cd $WXDIR/wxPython/demo
 | 
						|
        python2.3 demo.py
 | 
						|
 | 
						|
   OS X NOTE: You need to use "pythonw" on the command line to run
 | 
						|
   wxPython applications.  This version of the Python executable is
 | 
						|
   part of the Python Framework and is allowed to interact with the
 | 
						|
   display.  You can also double click on a .py or a .pyw file from
 | 
						|
   the finder (assuming that the PythonLauncher app is associated with
 | 
						|
   these file extensions) and it will launch the Framework version of
 | 
						|
   Python for you.  For information about creating Applicaiton Bundles
 | 
						|
   of your wxPython apps please see the wiki and the mail lists.
 | 
						|
 | 
						|
   SOLARIS NOTE: If you get unresolved symbol errors when importing
 | 
						|
   wxPython and you are running on Solaris and building with gcc, then
 | 
						|
   you may be able to work around the problem by uncommenting a bit of
 | 
						|
   code in setup.py and building again.  Look for 'SunOS' in setup.py
 | 
						|
   and uncomment the block containing it.  The problem is that Sun's ld
 | 
						|
   does not automatically add libgcc to the link step.
 | 
						|
 | 
						|
 | 
						|
 | 
						|
 | 
						|
Building on Windows
 | 
						|
-------------------
 | 
						|
 | 
						|
The Windows builds currently require the use of Microsoft Visual C++.
 | 
						|
Theoretically, other compilers (such as mingw32 or the Borland
 | 
						|
compilers) can also be used but I've never done the work to make that
 | 
						|
happen.  If you want to try that then first you'll want to find out if
 | 
						|
there are any tricks that have to be done to make Python extension
 | 
						|
modules using that compiler, and then make a few changes to setup.py
 | 
						|
to accomodate that.  (And send the patches to me.)  If you plan on
 | 
						|
using VisualStudio.Net (a.k.a. MSVC 7.1) keep in mind that you'll also
 | 
						|
have to build Python and any other extension modules that you use with
 | 
						|
that compiler because a different version of the C runtime library is
 | 
						|
used.  The Python executable that comes from PythonLabs and the
 | 
						|
wxPython extensions that I distribute are built with MSVC 6 with all
 | 
						|
the Service Packs applied.  This policy will change with Python 2.4
 | 
						|
and MSVC 7.1 will be used starting with that version.
 | 
						|
 | 
						|
If you want to build a debuggable version of wxWidgets and wxPython you
 | 
						|
will need to have also built a debug version of Python and any other
 | 
						|
extension modules you need to use.  You can tell if you have them
 | 
						|
already if there is a _d in the file names, for example python_d.exe
 | 
						|
or python23_d.dll.  If you don't need to trace through the C/C++ parts
 | 
						|
of the code with the debugger then building the normal (or hybrid)
 | 
						|
version is fine, and you can use the regular python executables with
 | 
						|
it.
 | 
						|
 | 
						|
Just like the unix versions I also use some scripts to help me build
 | 
						|
wxWidgets, but I use some non-standard stuff to do it.  So if you have
 | 
						|
bash (cygwin or probably MSYS too) or 4NT plus unix-like cat and sed
 | 
						|
programs then there is a copy of my wxWidgets build scripts in
 | 
						|
%WXDIR%\\wxPython\\distrib\\msw.  Just copy them to
 | 
						|
%WXDIR%\\build\\msw and you can use them to do your build, otherwise
 | 
						|
you can do everything by hand as described below.  But if you do work
 | 
						|
by hand and something doesn't seem to be working correctly please
 | 
						|
refer to the build scripts to see what may need to be done
 | 
						|
differently.
 | 
						|
 | 
						|
The \*.btm files are for 4NT and the others are for bash.  They are::
 | 
						|
 | 
						|
   .make/.make.btm	  Builds the main lib and the needed contribs
 | 
						|
   .mymake/.mymake.btm	  Builds just one lib, use by .make
 | 
						|
   .makesetup.mk	  A makefile that will copy and edit setup.h
 | 
						|
			  as needed for the different types of builds
 | 
						|
 | 
						|
Okay.  Here's what you've been waiting for, the instructions!  Adapt
 | 
						|
accordingly if you are using the bash shell.
 | 
						|
 | 
						|
1. Set an environment variable to the root of the wxWidgets source
 | 
						|
   tree.  This is used by the makefiles::
 | 
						|
 | 
						|
         set WXWIN=%WXDIR%
 | 
						|
 | 
						|
2. Copy setup0.h to setup.h::
 | 
						|
 | 
						|
         cd %WXDIR%\include\wx\msw
 | 
						|
         copy setup0.h setup.h
 | 
						|
 | 
						|
 | 
						|
3. Edit %WXDIR%\\include\\wx\\msw\\setup.h and change a few settings::
 | 
						|
 | 
						|
         wxDIALOG_UNIT_COMPATIBILITY    0
 | 
						|
         wxUSE_DEBUG_CONTEXT            1
 | 
						|
         wxUSE_MEMORY_TRACING           1
 | 
						|
         wxUSE_DIALUP_MANAGER           0
 | 
						|
         wxUSE_GLCANVAS                 1
 | 
						|
         wxUSE_POSTSCRIPT               1
 | 
						|
         wxUSE_AFM_FOR_POSTSCRIPT       0
 | 
						|
         wxUSE_DISPLAY                  1
 | 
						|
 | 
						|
   If you are using my build scripts then a few more settings will be
 | 
						|
   changed and then a copy of setup.h is placed in a subdir of
 | 
						|
   %WXWIN%\\lib\vc_dll.  If you are doing it by hand and making a
 | 
						|
   UNICODE build, then also change these::
 | 
						|
 | 
						|
         wxUSE_UNICODE                  1
 | 
						|
	 wxUSE_UNICODE_MSLU             1
 | 
						|
 | 
						|
   If you are doing a "hybrid" build (which is the same as the
 | 
						|
   binaries that I release) then also change these::
 | 
						|
 | 
						|
         wxUSE_MEMORY_TRACING           0
 | 
						|
         wxUSE_DEBUG_CONTEXT            0
 | 
						|
 | 
						|
 | 
						|
4. Make sure that %WXDIR%\\lib\\vc_dll directory is on the PATH.  The
 | 
						|
   wxWidgets DLLs will end up there as part of the build and so you'll
 | 
						|
   need it on the PATH for them to be found at runtime.
 | 
						|
 | 
						|
 | 
						|
5. Change to the %WXDIR%\\build\\msw directory 
 | 
						|
 | 
						|
     	 cd %WXDIR%\\build\\msw
 | 
						|
 | 
						|
 | 
						|
6. If using my scripts then use the .make.btm command to build
 | 
						|
   wxWidgets.  It needs one command-line parameter which controls what
 | 
						|
   kind of build(s) to do.  Use one of the following::
 | 
						|
 | 
						|
         debug          Build debug version
 | 
						|
         hybrid         Build hybrid version
 | 
						|
         both           Both debug and hybrid
 | 
						|
         debug-uni      Build a debug unicode library
 | 
						|
         hybrid-uni     Hybrid unicode (see the pattern yet? ;-)
 | 
						|
         both-uni       and finally both unicode libraries
 | 
						|
 | 
						|
   For example::
 | 
						|
 | 
						|
         .make hybrid
 | 
						|
 | 
						|
   You can also pass additional command line parameters as needed and
 | 
						|
   they will all be passed on to the nmake commands, for example to
 | 
						|
   clean up the build::
 | 
						|
 | 
						|
         .make hybrid clean
 | 
						|
 | 
						|
   If *not* using my scripts then you can do it by hand by directly
 | 
						|
   executing nmake with a bunch of extra command line parameters.
 | 
						|
   The base set are::
 | 
						|
 | 
						|
	-f makefile.vc OFFICIAL_BUILD=1 SHARED=1 MONOLITHIC=0 USE_OPENGL=1
 | 
						|
 | 
						|
   If doing a debug build then add::
 | 
						|
 | 
						|
       BUILD=debug 
 | 
						|
 | 
						|
   otherwise add these::
 | 
						|
 | 
						|
       DEBUG_FLAG=1 CXXFLAGS=/D__NO_VC_CRTDBG__ WXDEBUGFLAG=h BUILD=release
 | 
						|
 | 
						|
   If doing a Unicode build then add these flags::
 | 
						|
 | 
						|
       UNICODE=1 MSLU=1
 | 
						|
 | 
						|
   Now, from the %WXDIR%\\build\\msw directory run nmake with your
 | 
						|
   selection of command-line flags as described above.  Repeat this
 | 
						|
   same command from the following directories in order to build the
 | 
						|
   contrib libraries::
 | 
						|
 | 
						|
	%WXDIR%\contrib\build\gizmos
 | 
						|
	%WXDIR%\contrib\build\xrc
 | 
						|
	%WXDIR%\contrib\build\stc
 | 
						|
	%WXDIR%\contrib\build\ogl
 | 
						|
 | 
						|
    Note, that the ogl lib build will need an additional flag::
 | 
						|
 | 
						|
	CPPFLAGS="-DwxUSE_DEPRECATED=0"
 | 
						|
 | 
						|
7.  When that is all done it will have built the main wxWidgets DLLs
 | 
						|
    and also some of the contribs DLLs.  There should be a ton of DLLs
 | 
						|
    and lots of lib files and other stuff in %WXDIR%\\lib\\vc_dll.
 | 
						|
 | 
						|
 | 
						|
8. Building wxPython on Windows is very similar to doing it for the
 | 
						|
   unix systems.  We're not going to install the development version
 | 
						|
   of wxPython with these commands, so it won't impact your already
 | 
						|
   installed version of the latest release.  You'll be able to test
 | 
						|
   with this version when you want to, and use the installed release
 | 
						|
   version the rest of the time.  If you ever do want to install the
 | 
						|
   development version please refer to INSTALL.txt.
 | 
						|
 | 
						|
   Change to the %WXDIR%\\wxPython dir and run the this command,
 | 
						|
   making sure that you use the version of python that you want to
 | 
						|
   build for (if you have more than one on your system)::
 | 
						|
 | 
						|
         cd %WXDIR%\wxPython
 | 
						|
         python setup.py build_ext --inplace 
 | 
						|
 | 
						|
   If you are wanting to have the source files regenerated with swig,
 | 
						|
   then you need to turn on the USE_SWIG flag and optionally tell it
 | 
						|
   where to find the new swig executable, so add these flags::
 | 
						|
 | 
						|
         USE_SWIG=1 SWIG=e:\projects\SWIG-cvs\swig.exe
 | 
						|
 | 
						|
   If you built a Unicode version of wxWidgets and want to also build
 | 
						|
   the Unicode version of wxPython then add this flag::
 | 
						|
 | 
						|
         UNICODE=1
 | 
						|
 | 
						|
   If you have a debug version of Python and wxWidgets and want to
 | 
						|
   build a debug version of wxPython too, add the --debug flag to the
 | 
						|
   command line.  You should then end up with a set of ``*_d.pyd``
 | 
						|
   files in the wx package and you'll have to run ``python_d.exe`` to
 | 
						|
   use them.  The debug and hybrid(release) versions can coexist.
 | 
						|
 | 
						|
   When the setup.py command is done you should have fully populated
 | 
						|
   wxPython and wx packages locally in %WXDIR%/wxPython/wxPython and
 | 
						|
   %WXDIR%/wxPython/wx, with all the extension modules (``*.pyd``
 | 
						|
   files) located in the wx package.
 | 
						|
 | 
						|
 | 
						|
9. To run code with the development version of wxPython, just set the
 | 
						|
   PYTHONPATH to the wxPython dir in the CVS tree.  For example::
 | 
						|
 | 
						|
        set PYTHONPATH=%WXDIR%\wxPython
 | 
						|
	cd %WXDIR\wxPython\demo
 | 
						|
        python demo.py
 | 
						|
 | 
						|
