Description michalciolek 2017-06-29 13:05:25 UTC 
Hello, 

I would like to compile the image for BeagleBone Black with QT5 and SGX (eglfs). 

My host: 
4.10.0-21-generic 
Ubuntu 17.04 x64 

I tried with branch 2017.05 and 2017.02.3: 

make beaglebone_defconfig
make menuconfig

I enabled: 
BR2_TOOLCHAIN_BUILDROOT_GLIBC
BR2_TOOLCHAIN_BUILDROOT_CXX
BR2_PACKAGE_TI_GFX
BR2_PACKAGE_TI_GFX_ES8
BR2_PACKAGE_QT5
BR2_PACKAGE_QT5BASE_EXAMPLES
BR2_PACKAGE_QT5BASE_GUI
BR2_PACKAGE_QT5BASE_EGLFS

After make I get error: 

/mnt/ssd2/buildroot/output/build/ti-gfx-5_01_01_02/GFX_Linux_KM/services4/srvkm/env/linux/osfunc.c: In function ‘pvr_dmac_inv_range’:

How to fix it?
Comment 1 Arnout Vandecappelle 2017-07-01 10:14:18 UTC 
As far as I know, ti-gfx is no longer supported and for recent SoCs with recent kernels you should use ti-gfx-km (and -um). That's why beaglebone_qt5_defconfig selects it. Is there any reason why you don't use that defconfig?
Comment 2 michalciolek 2017-07-04 14:40:59 UTC 
I followed the tutorial: http://vanguardiasur.com.ar/opengl-es-on-beaglebone-black/ and I did not know that ti-gfx is no longer supported... With (beaglebone_qt5_defconfig) ti-gfx-km (and -um) options works! Thanks!

Could you contact the people on that site and ask them to update their page to use the beaglebone_qt5_defconfig?
