OpenSceneGraph @3.0.1 Runtime error - infinite recursion on sinf

[Eduardop]

The OpenSceneGraph port has a runtime infinite recursion bug when the function sinf is called, as well as other math functions. This is described here:

I prepared the attached fix.

Patch for OpenSceneGraph - file updated

Updated with the proper patch-include-osg-Math.diff​ file, sorry about the mistake.

If this is not a build error, but a runtime error, then the revision must be increased so that existing users are prompted to upgrade.

There is no "revision" line in the Portfile, should one be added?

Replying to poyart@…:

Yes, and set it to “1”.

After having built the software I only now manage to test it, but I seem to be unable to let it open up a display window:

$ osgviewer robot.osg 
View::setUpViewAcrossAllScreens() : Error, no WindowSystemInterface available, cannot create windows.
Viewer::realize() - failed to set up any windows
View::setUpViewAcrossAllScreens() : Error, no WindowSystemInterface available, cannot create windows.
Viewer::realize() - failed to set up any windows

Any idea what I am missing?

What windowing system is it supposed to use? Given the license, it would seem to be wxWidgets, yet there is no dependency on it. Maybe a dependency on wxWidgets30 would be useful. Also the port may need to be modified to recognize it.

robot.osg is one of the many test files from OSG's standard test files downloaded from its website at

The error described in comment:9 can be fixed by building with:

sudo port install openscenegraph configure.args="-DOSG_WINDOWING_SYSTEM=Cocoa"

Is there a way to make that option be the default?

Also, this bug is related to the sinf error. This is a different problem. Maybe the sinf bug should be closed and another one opened.

Thanks for the hint, poyart!
