Hi all, Hi Jeremy,

As I mentioned a little while ago, I stopped trying to get osgCairo and osgPango working on Windows because of time constraints (it was just for a personal project, so it didn't have much priority)... Well I've gone back to it tonight, and have some progress to report.

First of all, there were some things missing for it to compile as a DLL on Windows, first and foremost an Export header where the correct symbol for _dllexport and _dllimport was defined depending on whether you're compiling or using the DLL respectively. I added that, so now the libs (both osgCairo and osgPango) compile correctly as DLLs.

Along the way I also added a few things I consider important to the CMake config, like the "d" suffix for side-by-side debug and release builds, and fields in osgPango's config to specify where to find osgCairo's includes and libs.

I had to add a few libraries to get things to link, like osgDB for osgCairo and cairo, gobject and glib for osgPango (it's looking for _g_free, _g_object_ref, etc for some reason).

I also had to make a few fixes to files that seem to me like they wouldn't compile without the fixes, even on Linux... Which seems weird. I updated earlier tonight from the googlecode SVN for the respective projects, but perhaps there's some code in flux.

Also, the osgpangoanimation example looks for osgAnimation (which isn't in OSG yet, so there should be a CMake option to compile that example or not and fields to specify where osgAnimation is) and the osgpangoguiviewer example seems to use methods and data members in osgWidget which don't exist (or is it that they're on the osgWidget branch but not in the main OSG SVN yet?).

Note that at this point I'm just getting things to compile. I haven't actually run anything yet. Status report would read as follows:

  * lib compiles            100%
  * all examples compile    100%

  * lib compiles            100%
  * 3/5 examples compile     60%

I'll send all my changes tomorrow (I'm too tired to package that all up right now - it's past Midnight, and I've got swimming classes with my youngest very early tomorrow morning... :-) ). Jeremy, I seem to remember you prefer SVN diffs, contrary to OSG's standard policy, is that right? I'll send the changes in whatever format you prefer tomorrow.

I'll also test some executions tomorrow, can you please give me a few command lines that would be good tests? I've seen some data in the SVN working copy, but I don't know how to use it.
