can not run qt3d executable file on AM335x starter kit

Hi,

I will forward this to the SW team.

Thank you for your support.
There was some steps which needed to complete. I had done all following steps. Still error remains same
steps for troubleshoot qt3d:
doc.qt.digia.com/.../qt3d-troubleshooting.html

Many Thanks and Regards

I Deep,

I need a bit more information regarding your self. What SDK are you using? You said you cross compiled qt3d so I'm assuming your trying to use Qt 5. Have you taken a look at the latest SDK for AM335x that was released recently? It already includes Qt 5 and the monkeygod demo is already in the filesystem (/usr/share/qt5/examples/qt3d)

hello,

I am using ti-­sdk-­am335x­-evm­-06.00.00.00. Qt version that I am using is qt 4 because library code does not succesfully compile on qt 5. There are many dependencies related to qt5 but it is easily compiled on qt 4. I had also run some basic example of qml and qt like helloworld but these qt3d example shows errors.

Thank you  

How did you build qt3d and what repository did you use?

I cloned git://gitorious.org/qt-quick3d/qt-quick3d.git
I sourced the SDK's environment-setup script
Ran qmake and then make.
All the files compiled successfully and I don't see any library files being built

So what were these library files that you copied over?

first of all to install qt4 my command is as follows

sudo apt-get build-dep qt4-qmake
sudo apt-get install libqt4-dev

for qt3d source I cloned
git clone github.com/.../qt3d.git
git checkout --track -b qt4 origin/qt4
export QMAKESPEC=/usr/share/qt4/mkspecs/linux-g++
sudo qmake-qt4
sudo make

library file generated in /usr/lib/x86_64-linux-gnu/
they are x86 executable
deep@deep:/usr/lib/x86_64-linux-gnu$ file libQt3D.so.1.0.0
libQt3D.so.1.0.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=0x26a9afd36ae0eeb1349b43b3ad2f1f9a364fbad8, not stripped

after that I crosscompiled using am335x-sdk-06.00.00.00
source ti-sdk-am335x-evm-06.00.00.00/linux-devkit/environment-setup
export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
qmake-qt4
make

so, ARM executable examples generated in bin folder of qt3d and libraries are generated in /usr/lib/x86_64-linux-gnu/ folder that are
deep@deep:/usr/lib/x86_64-linux-gnu$ file libQt3DE.so.1.0.0
libQt3DE.so.1.0.0: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, BuildID[sha1]=0x3e42bfaaf648ba3eed1f2a605a60692a8bfd32be, not stripped

deep@deep:/usr/lib/x86_64-linux-gnu$ file libQt3DQuickE.so.1.0.0
libQt3DQuickE.so.1.0.0: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, BuildID[sha1]=0x4cf004ee16bc7af0e76c93746a050cfc02c55366, not stripped

at time of crosscompilation, I also copied these lib files in toolchain lib folder.

these ".so" files I copied into my am335x sk hardware in /usr/lib/ folder
and also copied qt4 's import and plugin folders into hardware /usr/lib/qtopia/ folder


Thank you

hello,

Actually qt3d source was following

git@gitorious.org:qt/qt3d.git

Still I am getting same error like

QGLContext::makeCurrent(): Cannot make invalid context current
Segmentation fault

kindly, help me to get through this problem.

Hello,

I think the problem is with gles2test

It gives following output

--------------------- started ---------------------                             
Error: Failed to open shader file 'glsltest1_vertshader.txt'!                   
--------------------- finished ---------------------   

while I execute qt3d library with support of powervr it gives following error

root@am335x-evm:~/qt3d/bin# ./monkeygod -qws -display powervr
