Is there a way to get the OpenGL shared context to work under Linux? I am using :configuration (:double-buffer t :rgba t :share <opengl::glxcontext>) This works both in OS X and Windows XP. I am using LW Personal Edition 4.4.6 in Ubuntu Linux 5.04. Regards, Mika

I finally took a look at the opengl source code provided by Lispworks. In (defmethod %make-context ((widget xt-lib:widget) opengl- configuration) it seems to me that (typep share 'glxcontext) blocks out the glxcontext pointer. This returns NIL even if there is a valid glxcontext as a parameter (I am using opengl::ensure-context to acquire a context). If I remove the test shared contexts work like charm in Linux too. t. Mika
