OpenGL ES2. Cross-compile for Beaglebone Black using OS Debian when built QT5.7.0

Dang Vu

Hi everybody, i have a troupble when i built the QT 5.7 everywhere for Beaglebone using OS debian (cross-compile on PC Ubuntu), i want "-opengl es2" in my configure but i encountering

OpenGL ES 2.x disabled.
The OpenGL ES 2.0 functionality test failed! You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL_ES2,

And i don't know to install OpenGL ES2.0 for ARM in my PC Ubuntu, i researched how to install OpenGL 2.0 to tool-chain for Beaglebone and i was readed about 200 result in google, topics discuss in QT forum but nothing can help me or fix the us the problem, Then, who ever install tool-chains OpenGL ES2 for Beaglebone on Ubuntu can help me? it took me one week to built it's, i was tired. Thanks for read!

exactly i want below:

Hi,

AFAIK, the files needed should be available in your BBB sysroot.

jastmc

Well. I haven't succeeded yet but to install OpenGL on BBB there is a guide here.

small_bird

You need to cross-compile mesa-12(a kind of implement for opengl es) and then link the headers and the libraries generated to Qt compiling.

Dang Vu

thanks! i'am try and anoucement late!

Dang Vu

@small_bird you can give me link about that? i was try Mesa and Mali but it's not success ( or i wrong some step) i really need a tutorial! thanks

small_bird

@Dang-Vu Of course, http://www.360doc.com/content/15/0108/18/5268588_439214065.shtml. It is the web site in China. Can you see that?

Dang Vu

@small_bird Hi sir! i built Mesa for arm with configure

./configure --prefix /usr/local/Mesa --target=arm-linux --host=arm-linux --enable-gles2 --enable-gles1 --enable-glx --enable-egl --disable-dri3 --enable-shared-glppi --with-egl-platforms=x11 --with-dri-driver=swrast CROSS_COMPILE=arm-linux-gnueabihf-

and install successed!
in linux-beagleboard-g++ qmake.conf i writen

but i still have an error

what can i do to built QT for beaglebone! i really- really need a tutorial! thanks! hix...

jsulm

@Dang-Vu What does

file /usr/local/Mesa/lib/libGLESv2.so

say?

Dang Vu

@jsulm Dir Sir! i make and install Mesa in here! i built Mesa with linaro toolchains(arm- linux-gnueabihf) !
i think

QMAKE_LIBDIR_EGL        =/usr/local/Mesa/lib

i right!? i can see libGLESv2.so in that(/usr/local/Mesa/lib)! but it not work when i configure QT with -opengl es2. you nees a that file? i cant send it for you!

jsulm

@Dang-Vu Can you please execute this command in a shell:

file /usr/local/Mesa/lib/libGLESv2.so

and post its output here?

This message:

/usr/local/Mesa/lib/libGLESv2.so: file not recognized: File format not recognized

means that the library has a wrong format. That's why I want to see the output of that command: it will tell for which CPU architecture it was built.

Dang Vu

@jsulm sorry Sir! my mistake, file /usr/local/Mesa/lib/libGLESv2.so.2.0.0 it 's tell me i only use for x86-linux but not for arm! well, while i configure Mesa

./configure --prefix /usr/local/Mesa --target=arm-linux --host=arm-linux --enable-gles2 --enable-gles1 --enable-glx --enable-egl --disable-dri3 --enable-shared-glppi --with-egl-platforms=x11 --with-dri-driver=swrast CROSS_COMPILE=arm-linux-gnueabihf-

what is step i wrong sir? i thinks i successed to built Mesa3d for Arm but it's not true! you can fix it's, Sir?

jsulm

@Dang-Vu How did you build Mesa for ARM?

Dang Vu

@jsulm i download Mesa3d from https://mesa.freedesktop.org/archive/13.0.1/mesa-13.0.1.tar.gz , in linux host( ubuntu16.04) i install linaro toolchains in terminal

$ sudo apt-get install gcc-arm-linux-gnueabi
$ sudo apt-get install g++-arm-linux-gnueabi
$ sudo apt-get install gcc-arm-linux-gnueabihf
$ sudo apt-get install g++-arm-linux-gnueabihf

and i configure Mesa below:

./configure --prefix /usr/local/Mesa --target=arm-linux --host=arm-linux --enable-gles2 --enable-gles1 --enable-glx --enable-egl --disable-dri3 --enable-shared-glppi --with-egl-platforms=x11 --with-dri-driver=swrast CROSS_COMPILE=arm-linux-gnueabihf-

i make and install succsed in /usr/local/Mesa

@Dang-Vu do you have finished with your problem?
i have same problem with u...
