Ok perfect, that work very fine! Thanks
That is strange, i never had libgbm-dev installed and got kmscube to work..
When I execute 'autogen.sh', the script notice me to get libgbm-dev:
git clone git://git.ti.com/glsdk/kmscube.git
cd kmscube/
./autogen.sh
...
checking for DRM... yes
checking for GBM... no
configure: error: Package requirements (gbm) were not met:
No package 'gbm' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables GBM_CFLAGS
and GBM_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
But it's very strange, because if I do just: apt remove libgbm1 --purge
I can execute normaly kmscube but I have a black screen.

Ok I try this :
root@beaglebone ~ # dpkg -l |grep ti-sgx
ii ti-sgx-ti335x-modules-4.14.108-ti-r101 1stretch
armhf
ti-sgx modules

root@beaglebone ~ # apt install libqt5qml5 qml-module-qtquick-controls

Reading package lists... Done
Building dependency tree
Reading state information... Done
The following additional packages will be installed:
libdrm-amdgpu1 libdrm-common libdrm-dev libdrm-etnaviv1 libdrm-exynos1
libdrm-freedreno1 libdrm-nouveau2 libdrm-omap1 libdrm-radeon1 libdrm-tegra0
libdrm2 libegl-mesa0 libegl1 libegl1-mesa *libegl1-mesa-dev* libevdev2 *libgbm1
*libgles2 *libgles2-mesa-dev* ...
Errors were encountered while processing:
/tmp/apt-dpkg-install-e1Iuir/076-libegl1-mesa-dev_18.1.9-1rcnee1~stretch+20190321_armhf.deb
/tmp/apt-dpkg-install-e1Iuir/077-libgles2-mesa-dev_18.1.9-1rcnee1~stretch+20190321_armhf.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
So I remove manually:
# dpkg -r ti-sgx-common-ddk-um
# apt --fix-broken install
Ok, there is no error now with apt command.
I execute the Qt example:
./dashboard
Could not initialize egl display
Aborted
Thin I really need the ti-sgx-common-ddk-um package and not
libegl1-mesa-dev/libgles2-mesa-dev!
This is not the way to go I guess.
It's certainly a silly question but.. Why do not you update directly the
libraries mesa-libgl1, mesa-libgles2 and libgbm?
