Re: Dual simultaneous framebuffer output

_Ralph_

Hello,

so I've compiled Qt to work with OpenGLES using this configure command:

./configure -prefix /home/ralph/qtdiy/targetinstalldir -embedded arm -platform qws/linux-x86-g++ -xplatform qws/linux-TIarmv7-g++ -depths 16,24,32 -qt-freetype -no-mmx -no-3dnow -no-sse -no-sse2 -no-sse3 -no-sse4.1 -no-sse4.2 -no-ssse3 -no-avx -no-cups -qt-mouse-pc -no-mouse-tslib -qt-mouse-linuxinput -plugin-mouse-pc -little-endian -commercial -opengl es2 -openvg -qt-gfx-transformed -qt-gfx-linuxfb -qt-gfx-multiscreen -plugin-gfx-powervr -D QT_NO_QWS_CURSOR -D QT_QWS_CLIENTBLIT

I had to edit linux-TIarmv7-g++/qmake.conf so that it had the following added to line 31 as otherwise it wasn't configuring properly:

-lsrv_um /home/ralphc/ezsdk/ti-ezsdk_c6a816x-evm_5_00_00_56/Graphics_SDK_4_03_00_02/gfx_dbg_es5.x/libusc.so

Most of the Qt demos work fine but the ones that use Qt _and_ OpenGL don't. I  should add that all the SGX 3D OpenGL-only demos run fine on my board (e.g. OGLESCoverflow, OGLES2ChameleonMan etc).

For example, the textures demo gives this error:

./examples/opengl/textures/textures -qws -display powervr
powervr: driver not found
Aborted

Please can someone help me? I've followed the instructions pretty closely but somewhere I've gone wrong. By the way, my powervr.ini looks like this:

[default]
WindowSystem=libpvrQWSWSEGL.so

Thanks,

Ralph

    Hi, I tried to send you a message to chat on IRC. While I'm here, here is the output of your SGX script:

    Ralph,

    The link below contains a target file system for DM816x Integra with pre-installed graphics SDK 4.03.00.02 and Qt 4.7.2

    https://gforge.ti.com/gf/download/docmanfileversion/266/4573/tfs_sgx_qt.tar.gz

    Qt has been built with the latest Graphics SDK and should be available at /usr/local/qt-4.7.2-ogles2.

    Please use this as your root file system and try running hellogl_es2 example

    Regards,

    Anand
