mingw?

wxPython Users

I'm trying to figure out if I can use mingw to rebuild wxPython from
source, on Win2k with Python 2.2 from python.org.

This page seems to indicate that it's possible:
  http://sebsauvage.net/python/mingw.html

But an earlier post about mingw on this list leaves me in doubt:
  http://aspn.activestate.com/ASPN/Mail/Message/1581946

Ultimately my goal is to rebuild a smaller wxPython sans certain classes
like wxFTP, wxDb*, etc. Possibly even having a little Python util to
help out:
  C:> stripwx.py wxFTP "wxDb*"

And then distribute my app as a "normal windows app".

Should I go with VC++ or mingw? If mingw, do I need to rebuild Python as
well? Most importantly, who has actually done this? :slight_smile:

I tried it in the past, but building the wxWindows DLL was terribly slow compileing, and crapped out during the link with an out of virtual memory error. IIRC that box had 256M RAM, but was running win98 so it didn't use it too effectivly...

In theory it should work. (I'd like to live in Theory, it sounds like a nice place! :wink: ) You just need to ensure that all the C++ parts (wxWindows, wxPython and any add-ons) are built with the same compiler. wxPython's setup.py will also need some tweaking in order for it to work as currenlty it is assuming VC++ flags and such.

If you can get mingw32 to work there is probably no reason not to use it, other than VC++ producing slightly smaller and faster optimized code on average, from what I hear.

If mingw, do I need to rebuild Python as well?

I don't think so. There is a web page somewhere about making extensions with mingw32 that work with the stock Python.

Here's a link <http://starship.python.net/crew/kernr/mingw32/Notes.html&gt; that deals with using mingw to compile DLLs for Python. It can be done. I wrote a couple of DLLs that allowed me to talk to USB 1.1 using this technique. Unfortunately this one's from 1999. I had a newer link somewhere, but have since lost it. I'll update you all if I can find it again.

Hmm - certainly a nice approach. One - maybe stupid - question though.
Why are you so concerned about size ? Will the application be downloaded ?
I just packed an application using wxPython and Twisted. The resulting self
extracting installer (including a installation wizard ala installshield) was
only 5mb. That includes everything to actually run the software.
Is it actually worth the effort (and time) spent just to reduce that to maybe
25% less ?

Just a thought. No critics. I concur with the notion of only packing what you
need and not do it like i.e. MS Word where I have the impression they copied
the whole development tree on the cd, just to not miss a file :slight_smile:

For shareware, yes. Plenty of shareware apps with lots of functionality
clock in at less than 2.5 MB. Having a program that is twice as large
will be a disadvantage.

And I'm hoping that I can cut it down to something more like 50%. :slight_smile:

Understood.
