Re: AW: Perl OpenGL Project
From a query to the SDL developers list, there appears to be a cygports version of SDL that uses gcc-4.3.4 and the X11 GLX instead of WGL. I haven't had a chance to try it but maybe it will resolve this issue as a binary install option: http://cygwin-ports.git.sourceforge.net/git/gitweb.cgi?p=cygwin-ports/SDL;a=tree Cheers, Chris On Mon, Jul 11, 2011 at 9:44 AM, Chris Marshall devel.chm...@gmail.com wrote: 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).

On 7/10/2011 2:16 PM, Tobias Leich wrote: I can build Alien::SDL, but too much tests are failing for SDL. I tried a CPAN install but it failed because the compiler could not produce a win32 binary. The cygwin gcc used to support a -mno-cygwin option but that has been removed. Now you need to either use the cygwin gcc with its cygwin DLL dependencies or you need to use the mingw compiler for native win32 builds. I'm sorry but I don't know further than that since I've not come up to speed on the MinGW build stuff yet. However, it should be possible to have SDL build for the X11 environment on cygwin as a default. That doesn't work at the moment (is there a way to force it?). My goal would be to use a cygwin SDL that supports the native win32 OpenGL platform so I would imagine that the mingw compiler approach would be preferrable for performance. However, it would be nice if the SDL on X11 worked out of the box as well---that might be simpler to sort out: just use *real* unix settings on cygwin instead of forcing win32. There have been a couple of FAIL reports generated for Alien::SDL by my attempts so far. The key for cygwin support seems to be don't blindly check both win32 and x11 buildability---you'll get yes for both which usually messes up the builds. If you allow a selection and then build appropriately then things work and it is possible to provide options for either (possibly even both but not clear if that would be useful or helpful as a use case).

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.
