Well I've got Viewkit 1.31 for Linux, supposedly compiled for libc6 by ICS in 1999, but the linker in gcc-4.5.2 doesn't seem to be able to use it, I'm getting tons of undefined reference errors:
undefined reference to `VkSimpleWindow::show()'
undefined reference to `VkSimpleWindow::hide()'
undefined reference to `VkComponent::okToQuit()'
undefined reference to `VkSimpleWindow::operator _WidgetRec*() const'
Most aggravating, If the linker can't link to a shared lib, why does it have to spew out dozens of error lines instead of just SAYING that it can't link!? I guess that would make too much sense...
