Re: [Gnash] Gnash output to an OpenGL texture

[mendez]

Dear All,

Well, you might remember that I was interested in putting the output  
of gnash on an OpenGL texture for later used by other applications. I  
have considered the Cairo renderer and ShivaVG but in all honesty what  
I really need is something that can interprete SWF files (as in, I  
need a powerful content creation tool that my non-programmer  
colleagues can use).

So, I ended up looking around the gui directory and indeed I found  
what I was looking for under SdlOglGlue::render() of sdl_ogl_glue.cpp,  
where I believe I can start putting my FBO stuff. So, all nice and  
good. Btw I am using the trunk version of gnash.

Now to really test it with my own app I need to do it under windows. I  
followed the instructions under  
http://wiki.gnashdev.org/Cross_building_with_mingw to cross compile it  
but sadly this didnt work* (tried with both the latest bzr version and  
with 0.85). The error message is that the compiler doesnt understand  
"-mthreads" (using g++ 4.3.3). Has anybody any idea how to resolve  
this? (I am using the sys-root given on the wiki). The configure I use  
is the following:

./configure --enable-gui=sdl --enable-media=none  
--host=i686-pc-mingw32 --build=i686-pc-linux-gnu --disable-plugins  
--with-top-level=../sys-root/mingw --enable-renderer=ogl

Is there any tutorial out there to compile gnash natively on windows  
instead of cross compiling it from linux?

    Thanks everybody!

          Erick



* special note: I had to do the following before running the configure  
if you care to know:
export CFLAGS=-I/home/myaccount/sys-root/mingw/include/

otherwise it couldnt finde "windows.h"
