I use a tool called SWIG (http://www.swig.org) to help generate the
C++ sources used in the wxPython extension module. However you don't
need to have SWIG unless you want to modify the *.i files. If you do

+you'll want to have version 1.1-883 of SWIG and you'll need to apply

I use the new Python Distutils tool to build wxPython. It is included
with Python 2.0, but if you want to use Python 1.5.2 or 1.6 then
space in it (i.e., NOT c:\Program Files\wx) and set an environment
variable named WXWIN to this directory. For example:
- mkdir \wx2
- cd \wx2
- unzip wxMSW-2.2.2.zip
- set WXWIN=c:\wx2
+ mkdir \wx2
+ cd \wx2
+ unzip wxMSW-2.2.2.zip
+ set WXWIN=c:\wx2
You'll probably want to add that last line to your autoexec.bat or
System Properties depending on the type of system you are on.
D. Change to the wx2\include\wx\msw directory and copy setup0.h to
setup.h and then edit setup.h. This is how you control which parts
of wxWindows are compiled into or left out of the build, simply by
- turning options on or off. At a minimum you should set the
- following:

- wxUSE_LIBTIFF 1
- wxDIALOG_UNIT_COMPATIBILITY 0

- I also turn off the following as they are not currently used in

- help save space, but I havn't investigated all the potential

- wxPython expects then you'll get link errors later on.

Be sure that wxUSE_GLCANVAS is defined to be 0 as wxPython now

DEBUG Specified with "FINAL=0" and produces a DLL named

- debugging information and with the __WXDEBUG__ set which
- enables some debugging-only code in wxWindows such as
- assertions and failure log messages. The /MDd flag is

C. Change to the wx2\src\msw directory and type the following command,
using the value for FINAL that you want:
- nmake -f makefile.vc dll pch USE_GLCANVAS=1 FINAL=hybrid
+ nmake -f makefile.vc dll pch FINAL=hybrid
Your machine will then crunch away for possibly a long time,
depending on your hardware, and when it's done you should have a
E. You can test your build by changing to one of the directories under
\wx2\samples or \wx2\demos and typing (using the right FINAL flag):
- nmake -f makefile.vc FINAL=hybrid WXUSINGDLL=1
+ nmake -f makefile.vc FINAL=hybrid WXUSINGDLL=1
and then executing the resulting .exe file.
either change these flags directly in setup.py or supply them on
the command-line.

- IN_CVS_TREE If you are using the CVS version of the
- wxWindows and wxPython sources then you will
- need to set this flag to non-zero. This is
- needed because some source files from the
- wxWindows tree are copied to be under the
- wxPython tree in order to keep Distutils happy.
- With this flag set then setup.py will
- automatically keep these copied sources up to
- date if the original version is ever updated.
- If you are using the tar.gz version of the
- Python sources then these copied sources are
- already present in your source tree.

C. To build and install wxPython you simply need to execute the
different command-line parameters you'll want to pass to setup (in
addition to possibly one or more of the above):
- FINAL: python setup.py install
+ FINAL: python setup.py install
+
+ DEBUG: python setup.py build --debug install
- DEBUG: python setup.py build --debug install
+ HYBRID: python setup.py HYBRID=1 install
- HYBRID: python setup.py HYBRID=1 install
+ NOTE: If you get an internal compiler error from MSVC then you
+ need to edit setup.py and add in the /GX- flag that is normally
+ commented out. Just search for "GX-" and uncomment it so it is put
+ into the cflags list.
D. At this point you should be able to change into the wxPython\demo
directory and run the demo:
- python demo.py
+ python demo.py
E. If you would like to make a test build that doesn't overwrite the
installed version of wxPython you can do so with one of these
commands instead of the install command above:
- FINAL: python setup.py build_ext --inplace
+ FINAL: python setup.py build_ext --inplace
- DEBUG: python setup.py build_ext --debug --inplace
+ DEBUG: python setup.py build_ext --debug --inplace
- HYBRID: python setup.py HYBRID=1 build_ext --inplace
+ HYBRID: python setup.py HYBRID=1 build_ext --inplace
This will build the wxPython package in the local wxPython
directory instead of installing it under your Python installation.
directory to the PYTHONPATH:
set PYTHONPATH=c:\wx2\wxPython
- cd c:\wx2\wxPython\demo
- python demo.py
+ cd c:\wx2\wxPython\demo
+ python demo.py
That's all folks!
