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).

Cheers,
Chris

I believe it already works on cygwin no?

A quick SDL heads up:  the Prima::OpenGL strawman implementation
is now working with POGL on cygwin using the native WGL OpenGL
drivers.  For project goal #3 below, I'll be trying to get SDL installed



on cygwin so that I can try using it with POGL for the OpenGL drawing.

Anyone already using SDL + POGL on cygwin (with the Mesa+GLX
rendering)?  Does SDL installation on cygwin use the X11+GLX
framework or the win32+WGL one---as in any bumps I can expect
ahead?

Thanks much,
Chris

Hi Chris,

I am interested in helping out! Any bugs I can tackle I will take. I am
also hoping to look at using some of the P5NCI optimizations chromatic



was talking about but I will wait for a while and learn the code base so
far.

P.S. It would be appreciated if you CC'd the sdl-devel@perl.org list. We
have several ppl on that list that are interested in this project

Announcing the new Perl OpenGL project site at
sourceforge.net.  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.

If you are interested in participating, please
contact me via email or through the sf.net
project page links at

http://sourceforge.net/projects/pogl/develop


Thanks!
Chris
