Qt development on A20

[srxa]

@ikozic
It is not strange, DRM or Direct Rendering Manager Device , together with DRI2 is for X11 server, and for XCB plugin, for eglfs only MALI device driver is enough. I think you need also UMP device driver for eglfs, but it is already loaded by kernel, or it is called in some script in my and yours image.

@srxa
Aha, got it. Great, thanks for clearing that out.

Yeah, UMP is automatically loaded with Mali. So far (knock on wood ), almost everything is functional for my project - quite buggy though, so I'll need a week or two to get everything polished.

I'll just repeat one more time, since I can't seem to learn myself - BEWARE of /dev/disp - too much dysfunctional crappy code there, and it's extremely buggy.

Hi,

@srxa
I tried to cross compile qtbase in Qt5.2.1 with your description, but I always get failed. Maybe from beging.

I don't compile new drivers for my A20-LIME, I've just download last debian image and there is no problem with loading drivers:

Code Select Expand

modprobe mali
modprobe drm
modprobe mali_drm

Also I have downloaded gcc-linaro-arm-linux-gnueabihf-4.8-2013.09_linux from https://releases.linaro.org/13.09/components/toolchain/binaries.

Configuration past without any problem with command:

Code Select Expand

..everywhere-opensource-src-5.2.1/qtbase # ./configure -device linux-a20olimex-g++ -device-option CROSS_COMPILE=/home/cosik/r_and_d/A20-lime/gcc-linaro-arm-linux-gnueabihf-4.8-2013.09_linux/bin/arm-linux-gnueabihf- -sysroot /mnt/a20 -opensource -confirm-license -optimized-qmake -release -make libs -prefix /usr/local/qt5olim2 -no-pch -nomake examples -nomake tests -no-xcb -eglfs -v

And after then, when I call make command, I get something like this at the end:

Any suggestions and tips?

Hi,

I noticed that I have problems with compile Qt with option -eglfs.

Any one have any idea what to do?

[Edit]
Problem solved, I found solution in this instruction:

Hi all! 
I have an Olinuxino-micro a20 with the last Debian image by Olimex, ssvb kernel and Mali libraries installed.

Now i'm trying to install QT5 on my Olinuxino-micro a20.
I installed "ia32-libs" on my host (Ubuntu 12.04 64bit), mounted my sd card (rootfs partition) in /mnt/a20/, cloned "cross-compile-tools" repo and ran the fixQualifiedLibraryPaths script. As toolchain i'm using "gcc-linaro-arm-linux-gnueabihf-4.8-2013.09_linux" (but i tryed also with 4.9 version). Then i downloaded qtsource 5.3.1, created the "linux-a20olimex-g++" folder and changed the qmake.conf and qeglfshooks_stub.cpp files, that are the same as the guide coz i have the same paths.

Now i have some problems with the ./configure, this is my command:

Code Select Expand

./configure -opengl es2 -device linux-a20olimex-g++ -device-option CROSS_COMPILE=/home/claudio/TirocinioSort/Toolchain/gcc-linaro-arm-linux-gnueabihf-4.8-2013.09_linux/bin/arm-linux-gnueabihf- -sysroot /mnt/a20/ -opensource -confirm-license -optimized-qmake -release -make libs -prefix /usr/local/qt5olim2 -no-pch -nomake examples -nomake tests -no-xcb -eglfs -v

You might need to modify the include and library search paths by editing
QMAKE_INCDIR_EGL, QMAKE_LIBDIR_EGL and QMAKE_LIBS_EGL in /home/claudio/TirocinioSort/QTSource/qt-everywhere-opensource-src-5.3.2/qtbase/mkspecs/devices/linux-a20olimex-g++.


I deleted some text above because of the 20000 chars limitation.
Can you give me some hints?

One last thing: following another guide (for cubieboard) when i had to prepare my board with libraries i've only installed these:

Code Select Expand

sudo apt-get install flex bison gperf libicu-dev libxslt-dev ruby
can be this the problem?

Thank you in advance, Claudio.

As it complains about jpeglib.h you look to need some tool(s)/etc for jpeg

Thank you for your tip  , btw i don't think that's the main problem. I'll wait for new hints.

Hi claudio,

Did you correctly compiled mali binaries? I had some similar problems to yours.

I also writing some tutorial how to compile Qt5 step by step from beginning, but status of this is pending.

Hi, ye i correctly compiled mali libraries and the test runs with no errors. Also ./configure works now, but i still have problems running the make command. Everytime i try to compile there is a new error, then i fix the error and when i try there is a new one. 

[Cosik]

But what kind of errors? It's necessary to know what errors you get.

[claudio]

My last error was this:

I found a workaround that says to put "#undef Bool" after includes into "qvariant.h" so now i'm trying again with make. But everytime i "fix" an error there is one new.

Ok, I probably know where is problem. You configure Qt with frame buffer or X11?

How did you build mali binary drivers?

I had similar problems when I configure wrong mali drivers.

[claudio]

For Mali i did:

Code Select Expand

git clone https://github.com/linux-sunxi/sunxi-mali.git
cd sunxi-mali
git submodule init
git submodule update
make config ABI=armhf VERSION=r3p2-01rel2 EGL_TYPE=framebuffer
make install

Then i tested them:

Code Select Expand

cd test
make
modprobe mali
modprobe drm
modprobe mali_drm
./test

And it was all ok, with the triangle and all parameters good.

Then qt: i ran this configure:

Code Select Expand

./configure \
-opengl es2 \
-device linux-a20olimex-g++ \
-device-option CROSS_COMPILE=/home/claudio/TirocinioSort/Toolchain/gcc-linaro-arm-linux-gnueabihf-4.8-2013.09_linux/bin/arm-linux-gnueabihf- \

[Cosik]

Ok, some more stupid question:

1. Did you link libraries with cross-compile-tools and arm-linux-gnueabihf-g++?

2. Did you clean directory before each build/configuration?

3. Did you install mali drivers as root?

[claudio]

1) yes

Code Select Expand

git clone git://gitorious.org/cross-compile-tools/cross-compile-tools.git
cd cross-compile-tools
sudo ./fixQualifiedLibraryPaths /mnt/a20/ /home/claudio/TirocinioSort/Toolchain/gcc-linaro-arm-linux-gnueabihf-4.8-2013.09_linux/bin/arm-linux-gnueabihf-g++

2)i think no

3)yes, btw i think tomorrow i'll try to re-do my Debian image from beginning.

I ask you one thing, i'm using official Debian image from Olimex (the release 7 that you can find here: https://www.olimex.com/wiki/A20-OLinuXino-MICRO#Linux)
Next i need ssvb kernel for mali support:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j5 uImage modules
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- INSTALL_MOD_PATH=output modules_install


is this right? i'm really desperate coz i tried so many things...
Thank you for your help
