Re: AW: Perl OpenGL Project
I took a look at compiling SDL by hand to see if I could figure out what is going on. It looks like the SDL build on cygwin using .configure assumes you'll want the native win32 build of SDL. As far as I can tell, the X11 version of SDL should work as well---we'll just have to rework the configure.in so it doesn't force win32 when all that perfectly good X11 stuff is already there... sigh. I'll put fixing the SDL configure.in to allow cygwin to build with X11 (as in *all* the other unix-ish systems) on the to do when I get around to it list. Thanks for taking a look at the problem. I think I can move forward with the SDL specific stuff on the native win32 perls (even though I would like to be able to run on cygwin as well).

Re: AW: Perl OpenGL Project
We had a couple of iterations but I think I ran out of time to work with it before I could try the final result myself. Since then, cygwin and SDL may have changed... --Chris On 7/10/2011 3:02 AM, Kartik Thakore wrote: I believe it already works on cygwin no?

A read-only git access is at git://pogl.git.sourceforge.net/gitroot/pogl/pogl I plan on updating the plan going forward but the immediate goals are: (1) Continue work with Dmitry Karasik to resolve win32 and cygwin build issues for his new Prima::OpenGL module at http://github.com/dk/Prima-OpenGL (2) Refactor the perl API bindings to OpenGL to use GLEW rather than rolling our own. That should allow for an immediate bump in OpenGL support to version 4.x. (3) Refactor the GUI/system inteface in OpenGL to be more platform *and* GUI toolkit portable. The current FreeGLUT default is very portable but abstracting the needed interface should allow it to be provided by *any* GUI library. This is already getting started (surprisingly quickly) in #1. (4) Replace platform OpenGL library detection in the Makefile.PL by an Alien::OpenGL or such approach. Maybe Alien::GLEW would be better here. (5) Move from EU::MM to Module::Build to reduce platform specific shell and make issues.
