5.0.1 was the last released version of CVI for Solaris. There have been post release updates to the run time engine and the environment.
CVI is known to be compatible with Solaris 2.4 through 2.8.
CVI for Solaris includes the full development environment (ie. compiler, debugger, UI editor, ...)
CVI windows on X windows are not window manager aware, so there should be no window manager dependancy. I know that Openlook and CDE/motif have been used successfully.
