hi Trolltech Team, >>" - A new font system and enhanced OpenGL ES support in Qtopia Core " could you please help us understand how is OpenGL ES supported? it seems that to be able to compile Qtopia Core with OpenGL ES we need some EXTERNAL files that are NOT supplied with Qtopia Core. so, what exeactly are those other files that we need to have, where to download, how to install, what to modify before we try to do the following with Qtopia Core: ./configure -embedded generic -opengl make make install in short: - what are the prerequisites to compile Qtopia-Core with "-opengl" and how to go about it? i understand we have OpenGL ES *specification* and some HEADER files we can get from Khronos, but where are the drivers? is this OpenGL ES emulated in QWS, do we need mesa? do we need native X11 OpenGL? just framebuffer? what are the performance of these "desktop" development drivers, how close is it to performance of "real" OpenGL ES hardware on TARGET device? does any embeded manufacturer makes specific drivers just for Qtopia and QWS? who writes QWS drivers for desktop/development platform, who writes the driver for real OpenGL ES embedded/target platform? do we, at all, as of now, have any *fully accelerated* OpenGL ES drivers that Qtopia/QWS can *USE* on development or some target platform? thank you, zelko ----- Original Message ----- From: Eivind Throndsen To: qt-interest@xxxxxxxxxxxxx Sent: Thursday, May 31, 2007 9:17 AM Subject: [ANNOUNCE] Qt and Qtopia Core 4.3 Now Available We are pleased to announce that Qt and Qtopia Core 4.3 are now available.

As previously explained on qtopia-interest: Yes. This is also true also for the other platforms. For instance on X11 you need to have some header files (gl.h, glu.h) and libraries (libGL, libGLU) preinstalled on your system. To enable OpenGL ES in Qtopia Core you need to have the headers GLES/gl.h, GLES/egl.h and libraries libGLES, libEGL preinstalled on your system. > > so, what exeactly are those other files that we need to have, where > to download, how to install, what to modify before we try to do the > following with Qtopia Core: > > > ./configure -embedded generic -opengl > make > make install > > > > in short: > - what are the prerequisites to compile > Qtopia-Core with "-opengl" and how to go about it? > > > > > i understand we have OpenGL ES *specification* and some > HEADER files we can get from Khronos, but where are the > drivers? is this OpenGL ES emulated in QWS, do we need > mesa? do we need native X11 OpenGL? just framebuffer? Where to get the drivers depends on what kind of platform you're targeting. If you're targeting a handheld device from ATI, contact ATI. If you're using Qtopia Core on x86 you might want to take a look at Mesa or Hybrid. (I've been thinking on writing a pre-integrated driver for Mesa for Qtopia Core, but that work hasn't even been started yet).

hi, >>To enable OpenGL ES in Qtopia Core you need to have the headers GLES/gl.h, >>GLES/egl.h and libraries libGLES, libEGL preinstalled on your system. thanks! - can you say where to find libGLES & libEGL, where, in which folder they should be copied (installed)? - do we use gl.h & egl.h from Khronos.com or Hybrid in any case, do we need to modify anything in them or anywhere else? ..we need to create foder "GLES" somewhere in Qtopia-Core directory-tree? where? can you suggest how we should build directory-tree? what is the FULL path of those files? ========================= >>Where to get the drivers depends on what kind of platform you're targeting.

>>Qtopia Core on x86 you might want to take a look at Mesa or Hybrid...
our development platform is x86 (Linux), i guess at first we just want to *develop*
("write it once"), so we are talking (at least) about *emulation* of OpenGL ES
however,
when we do want to *port it* to another hardware, say: -
"..targeting a handheld device from ATI, contact ATI"
then, for what drivers we aks, drivers for "QWS on Linux"?
they "barely" have drivers for Win CE,
i dont recall any ES drivers for X11 or Qt/Qtopia?
i've been trying hard, but dont see anything that would suggest how to use
Mesa or Hybrid or anything with QWS (on any platform)
is there anything really there, that we can download right now
and have OpenGL DEMOS run on QWS?
or do we need to "make" simple "implementation"?
=============================
> To enable OpenGL ES in Qtopia Core you need to have the headers GLES/gl.h,

can you explain what "to enable OpenG ES" actually means?
- is "to enable" enough to compile Qtopia-Core including OpenGL DEMOS?
- is it enough to *display* those demos in QWS?
or for that we need *drivers* as well?
- can we compile without the drivers and run where drivers exist?
==============================================
but the very basic question that i still can not figure out is this:
drivers are NOT made for "platforms" like x86, PowerPC, ARM..
they are always made for WINDOWING SYSTEMS, like Win CE, X11...
i've never heard about QWS drivers ?? who makes them?
do we really ask ATI about OpenGL ES drivers for QWS on Linux?
as i understand,
Qtopia has its OWN 2D *generic* drivers that work on ANY
framebuffer (embedded device or desktop, x86 or ppc...)
...is this correct?
cheers,
zelko
