Re: [Gnash] Gnash output to an OpenGL texture

[Andrea Palmatè]

Hi,
you have to patch the configure file to have the faster solution, but i 
think there is something wrong with your compiler since it should 
recognize -mthreads

 *mingw* | *cygwin*)
   pthread_flags="-mthreads"
   ;;

So check first of all if the compiler is ok, or try also cygwin that 
imho is better to use and has almost all dependencies ready to use

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"

Framebuffer objects)?

I don't believe you can specifically do that now(perhaps with the
Cairo renderer??) -- but you can easily access the RGB data that AGG
outputs and write some code to put that on whatever surface you want.
Take a look at the code in the gui/ directory for how the various
display engines access it (or the "dump" command-line option that
ouputs raw RGB frames).

Good luck, it sounds like a cool project.
