enable eglfs

Hello,
I'm trying to add the Qt5/webkit support to the raspberryrpi_defconfig. In the ncurses configuration window I see this message:

"eglfs backend available if OpenGLES and EGL are enabled"

I searched for OpenGLES symbol (F8) but it found nothing. I don't understand how to enable the OpenGLES and EGL in order to allow the eglfs backend.

You need to enable a provider of opengl. In your case, you need rpi-userland, but in general these are the current choices:

grep -rn 'select BR2_PACKAGE_HAS_OPENGL_' package/
package/freescale-imx/gpu-viv-bin-mx6q/Config.in:7: select
BR2_PACKAGE_HAS_OPENGL_EGL
package/freescale-imx/gpu-viv-bin-mx6q/Config.in:8: select
BR2_PACKAGE_HAS_OPENGL_ES
package/ti-gfx/Config.in:3: select BR2_PACKAGE_HAS_OPENGL_EGL
package/ti-gfx/Config.in:4: select BR2_PACKAGE_HAS_OPENGL_ES
package/rpi-userland/Config.in:7: select BR2_PACKAGE_HAS_OPENGL_EGL
package/rpi-userland/Config.in:8: select BR2_PACKAGE_HAS_OPENGL_ES
package/sunxi-mali/Config.in:3: select BR2_PACKAGE_HAS_OPENGL_EGL package/sunxi-mali/Config.in:4: select BR2_PACKAGE_HAS_OPENGL_ES

To know which symbol to grep for, I looked at the help of the comment you mentioned, to see what it depended on.

Best regards,
Thomas
