I may be confusing two issues but seems I got OSG to build some of the examples (osgViewer using GraphicsWindowX11.cpp). It took a little tweaking in the cmake config - paths are real critical. Is that just building X apps with OSG as opposed to OSG being built as X. Even though you use a configuration heavy on X - it still build OSG as native Windows. It would help if Christopher would post the errors - I've had enough issues over time - I've probably seen it. I see he has posted a dump.

There's no secret, really :) I have built OSG with versions 1.5 and 1.7 and gcc 4 and 3 without any problem. My CDash build is a proof of it. Maybe Christopher is mixing X OpenGL headers with the windows ones, but I can't say if I can't see any error messages. Since I was building OSG in a daily basis on Cygwin I though it could be useful volunteer in order to add it into precompiled packages. Sadly, someone on the Cygwin list just told me that my OSG package would only be included in Cygwin if it used the X subsystem instead of the native windows one. That would render the library without hardware acceleration, so I'm thinking if in that way the package could be useful at all.

Hi Christopher, I can't help directly as I have no Cygwin/Mingw experience, but I can say there is a nightly build of both up on the OSG CDash page: http://www.cdash.org/CDashPublic/index.php?project=OpenSceneGraph There aren't any errors being reported for either Cygwin so it should be possible to get things building on your machine given the right set up of Cygwin. Hopefully this should provide a little encouragement that it is possible, exactly what to tweak I'll have to defer to those who've set things up under Cygwin.
