wxmsw26uh_vc.dll

Hi

running Win XP, Python 2.4 with matlibplot and wxpython installed from these executables both down-loaded from sourceforge

matplotlib-0.87.7.win32-py2.4.exe
wxPython2.6-win32-ansi-2.6.3.3-py24.exe

Just taking the first steps with matplotlib and wxpython using wxmpl. Running one of the wxmpl test apps I get this error message

python.exe - Unable to locate component

"This application has failed to start because wxmsw26uh_vc.dll was not found. Reinstalling this application may fix this problem"

After dismissing the message box, the app pops up and runs OK so I guess the error is not that serious but still pretty irritating to users. Tried reinstalling but that doesn't help. Also did a google search on wxmsw26uh_vc.dll and it seems that several people have reported this problem but I couldn't find a solution. One of the discussions I did find mentioned unicode versions of wxpython but AFAIK I have never installed a unicode version.

All suggestions gratefully received!

Installing the unicode version of wxpython is the solution. This will
get rid of the error message. Matplotlib is compiled against it.

Isn’t this a maint headache for you and others maintaining matplotlib?

Will there be wxPython 2.6, 2.7 and 2.8 builds?

Is it not possible to have a wxPython nutral build?

Best regards

Werner

Among other things. :wink:

I hope not. I am guessing that wxPython is like the linux kernel, so
2.7 is a dev branch.

The native interface was added for high speed blitting/animation. A
while back we talked about and agreed on trying to remove the native
interfaces for gtk and wxpython to avoid these compilation headaches.
This was after having decent success with pure python approaches for
qt3 and qt4. We are sticking with the unicode wxpython build for the
remainder of 0.87.x to avoid more confusion. Ideally 0.88 will have
the pure python blitting implementations.

Yes, 2.7 is a dev branch which normally lasts for quit some time, however this time round they are hoping to move to 2.8 pretty quickly, I believe before the end of the year.

That is good news.

yup -- and hoping to get it included in OS-X 10.5

wxPython 2.7 (and, of course, 2.8) has some extra methods for dumping binary data directly into wxBitmaps, so pure Python methods should be just as fast as C++ ones. Of course, that's only wxPython-version neutral for 2.7+ versions.

Good plan.

Ideally 0.88 will have the pure python blitting implementations.

I (and others) posted a bunch of information about how this could be done in that thread a while back. Is anyone planning on doing it? I'd be glad to consult, but don't have the time to do it myself right now (and I'm not using MPL much at this point, so It's hard to justify)
