QT/X11(xsgx) building - Graphics_SDK_4_04_00_01

Avijit Sur

We tried to build QT/X11 using prebuilt XSGX libraries that comes with Graphics_SDK_4_04_00_01.
But while configuring QT-4.6.3 with "-xrandr" "-xrender" "-xcursor" options, configure script throws error as
libXcursor.so, libXrandr.so, libXrender.so libraries  are not present.

Are these libraries part of freedesktop's kdrive ? If so, where from we can get proper version of X11/XSGX source and how we can build it
for our EVM3530/3730 board ? Also we want to configure QT/X11(XSGX) and build QT.  So we require the configure options and qmake.conf. 
Your help in this regard would be appreciated.

Our Board and sdk versions are -

  1)  Board - TI EVM3530/3730 Rev D (hynix) processor module on Mistral EVM main board (Rev G).
  2)  sdk - AM37xSDK_05_02_00_00 (psp kernel - 2.6.37)
  3)  Graphics_SDK_4_04_00_01
  4)  toolchain - codesourcery arm-2011.03-41

    Standalone build of X11 is not recommended - should use OpenEmbedded/ Angstrom build mechanism, that include Qt/X11.

    Could you please elaborate more on this ?

    Would be very helpful if you can  point to some documents  detailing configure and build steps. 

    Thanks Prabindh Sundareson.

    The Xorg prebuilt libraries are only provided for reference. Given the same toolchain - you should only pick up the Xorg.conf details, and powervr.ini settings, and then use the graphics library setup in your own filesystem generated out of buildroot or OE.

    Please refer to the latest installation guide at,

    Hi Ayjit,

    I just found your post. I realise I'm posting a while after your original post but did you succeed in solving your problem of building and running X? I am using Buildroot and have exactly the same problems as you as in this thread:

    http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/171553.aspx

    It's a different processor but the fundamentals are the same. Would be great to hear if you succeeded. I'll post an update if I succeed.

    Hi Ralph,

    I feel excited sharing my experiences here. Yes! I finally managed to build our filesystem with buildrootfs, Qt-4.6.3/Xsgx/GSDK-4.04.00.01.

    But I strongly agree what Prabindh(TI employee) recommended and therefore, it should be followed.

    I initially built Qt-4.6.3/X11 without xrandr, xrender and xcursor options as libXcursor.so, libXrandr.so and libXrender.so prebuilt libraries were not available. But we could not afford losing some X11 features in our application and therefore, QT/X11 was needed to be built with these libraries too.

    We found that omap35x_graphics_sdk_3.01.00.06 release has these prebuilt libraries. So, we took these libraries from omap35x_graphics_sdk_3.01.00.06 and finaly built Qt-4.6.3/X11(x11r6_sgx) with openGLES2 support. Our application mostly worked fine but found some performance issues in 2D QT-openGLES2 texturing for video frame rendering.   

    But this standalone build approach is not recommemded as you may encounter library version mismatch between releases, libc error from your own filesystem/toolchain and many many others needless to mention!!!!!!!

    Hi Avijit,

    That's good to hear but it sounds like you were using the pre-built X that came with the graphics SDK rather than building it yourself - is that correct? I have had the pre-built X ("XSGX") that came with the graphics SDK working fine with my own Linux system, I am just trying to integrate acceleration into my own home-made X. You are certainly right about the module vesion mismatch - I have copied over a file called pvr_drv.so from the graphics SDK and it was built for X server version 1.9.0 whereas I have X 1.7.5 in my build system. :'-(

    Thanks,

    Ralph

    Thanks Ralph and Prabindh.

    Yes Ralph, you are correct. I only used prebuilt Xsgx binaries and built QT using those. 

    Seems you are deep into Xorg source code. Good luck!!
