OK. I see why I was confused. I've never built PyQt4 with support for those classes against Qt 4.1 or earlier.

I meant that there is a bug in Qt prior to v4.2 in that QX11EmbedContainer::error() and QX11EmbedWidget::error() are declared in the .h file, described in the documentation, but not implemented in the .cpp file.

I think I was quite confused about when it was introduced, so ignore my comment about availability in versions before Qt 4.2. I seem to remember that it was introduced in Qt 4.0: http://blogs.qtdeveloper.net/archives/2005/08/10/playing-around-with-xembed/ In theory, then, any recent PyQt4 snapshot should work without problems unless the underlying QtGui library is built without these classes.

It's very close to the answer. It looks like QX11EmbedContainer and QX11EmbedWidget have been included unconditionally when they should only be included if you're building against Qt 4.2. Comment out or remove this line in sip/QtGui/QtGuimod.sip: %Include qx11embed_x11.sip Or, if you're not in a hurry, you could just wait for Phil to fix it in a later snapshot. That way, you'll be able to use the same source package to build libraries for use with Qt 4.1 and Qt 4.2.
