SimpleGL :: libqscreensimplegl.so :: driver cannot connect problem

KrishnaPavan — Tue, 28 Feb 2012 08:16:16 GMT

Hi,

I am using Qt_Every_Where_OpenSource_4.7.4. on Ubuntu10.04LTS.
I am using Qt_Embedded for ARM. I have successfully built Qt for target.

Info about SimpleGL can be found here :: SimpleGL

I also have libqscreensimplegl.so in
<Qt_Every…..Source>/plugins/gfxdrivers/libqscreensimplegl.so

I ran make & sudo make install, but it is not available in the
/usr/local/Trolltech/Qt-target-version/plugins/

gfxdrivers directory itself is not present in the /usr/local/Troll…/…../plugins/ directory.

I am facing a problem when this is used on target.
How to get that ported onto target’s rootfs?

Please Suggest!

Thanks :: Krishna Pavan

Hi Krishna,

I compile QT application/Library outside ltib in this way, it was working also fro simplegl on my side, hope it will be the same for you:

[ ! -d /usr/local/Trolltech ] && sudo ln -s <full/path/to/your/rootfs/>/usr/local/Troltech /usr/local/Trolltech

(basically it checks the the link does not exist already and if does not it create it).

export PATH=$PATH:</full/path/to/crosscompiler/used/for/building/qt-4-i.MX>

Then in the directory of the applcaition library you want to build

/usr/local/Trolltech/qt-everywhere-opensource-src-4.7.4/bin/qmake

make

make install (<-- this will probably sudo because it is the owner of the rootfs...)

Ciao

Thanks Daniele,

I have installed and I have target rootfs, I have also got SimpleGL plug-in.

But, As you can see, the library for SimpleGL is not present by default.

If you can check in <SourceDirectory>/src/plugins/gfxdrivers/ here you should have libqscreensimplegl.so, which is not available by default. Please check in your system.

Instead you should get it gone by downloading the code and prepare it.

By means of default procedure, I was able to get all the libraries, demos, examples for Target.

But simpleGL is something which I made using qmake & make.

SimpleGL library is now available in <qt_Source_directory./plugins/gfxdrivers/

But how to place it in /usr/local/TrollTech/Qt_target_version/plugins/gfxdrivers/ is what I could not understand at all.

Do you have libqscreensimplegl.so in /usr/local/TrollTech/Qt_target_version/plugins/gfxdrivers/ ?

Thanks & Regards :: Krishna Pavan

Hi Krishna,

Yes I know, I found this procedure for installing simplegl and quick3D, indeed :)

The link I make at the begin plays the trick :) such that when you do make install

anything that has to go under QT_targe_version get copied there.

Give it a try and let me know.

Hi Daniele,

I ran this in my source directory

pavan@ubuntu/qt-target$[ ! -d /usr/local/Trolltech ] && sudo ln -s /usr/local/Trolltech/Qt-target-version /usr/local/Troltech

later on I updated my make file with

pavan@ubuntu/qt-target$/usr/local/Trolltech/Qt-target-version/bin/qmake

By doing this I have updated my Makefile

later I ran make and sudo make install in my source directory.

I got nothing like plugins/gfxdrivers/libqscreensimplegl.so in my target_filesystem which is on my Host.

Hi Krishna,

Sorry but I would expect a different directory configuration:

In my case I use LTIB for building QT, using the patches you can find in this forum.

Once build is complete I have /home/daniele/MX/53/ltib/rootfs/

Which represent the targetfs with /home/daniele/MX/53/ltib/rootfs/usr/local/Trolltech/

containing the installation files for QT and other utilities. This folder will be linked

to /usr/local/Trolltech/

The method I showed you it assumes you've followed these steps, otherwise I fear it would not work.

Hi Daniele,

Thing is that, I copy /usr/local/Trolltech/Qt-target-version to /ltib/rootfs/usr/local/Trolltech/ once I get everything in the /usr/local/Trolltech/Qt-target-version properly.

Difference is that you make a link, so that every change gets reflected as it is an when it is done.

I copy once everything is fine.

So, Procedurally, everything is proper, with you as well as me.

I have made a demo application and ran it on my board.

demo of fluidlauncher executed properly.

But my application requires simplegl, which is thrown as an error, that is when I recognised that it was missing in /plugins/gfxdrivers directory.

file_list_host is a list of files on my host

file_list_target is a list of files on my target

Where you can see that, liqscreensimplegl.so is present on Host but not on target.

Hi Krishna,

Definitely there are many equivalent ways for building QT.

Here is my method, since it looks you are stuck, you may want give it a try... It is valid for mx51/mx53

Get FSL BSP and install it without forgetting to add the drivers for the gpu.

Copy the attached spec into

ltib/dist/lfs-5.1/qt/

./ltib -p qt-embedded.spec -f

This should align with my build and you can start the procedure originally mentioned.

On my side it did work...

Hi Daniele,

The (document) spec file is a good work, which will ease out many tasks.

However, XTRA_OPTS will facilitate phonon inclusion more as it is used, clearly.

Probably, I should add/include support for SimpleGL.

Thanks for giving me something which could get me something.

Let me try it and inform you.

Hi Daniele,

This is what I am facing trouble with.

Please Suggest!

Hi Krishna

Which BSP version are you using?

Also ltib offer 2 GPU drivers amd-gpu-bin-mx51 and amd-gpu-x11-gpu-bin-mx51, which of the 2 you added?

The right one for this case is the former.

Hi Daniele,

Thank You for your reply.

I am using ltib 9.1.1 for i.MX51, BSP is 10.07.

I am using amd-gpu-bin-mx51.

From above screenshot, I see that QEgl is fine, but SimpleGL seems to be facing some problem.

Did you have libqcscreensimplegl.so? in your rootfs?
