--- Comment #10 from Peter Seiderer <ps.report@gmx.net> ---
(In reply to Martin from comment #9)

Hello Martin,

can reproduce your problem with the given defconfig (independent of the custom
setting BR2_HOST_DIR or using the default).

Using sunxi-mali-mainline I get:

    $ readelf -d target/usr/bin/qtdiag | grep libGLESv2
    0x00000001 (NEEDED)                     Shared library:
[/my_build_path/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/libGLESv2.so]


Same defconfig changed to rpi-userland leads to:

    $ readelf -d target/usr/bin/qtdiag | grep libGLESv2
    0x00000001 (NEEDED)                     Shared library: [libGLESv2.so]


For sunxi-mali-mainline:

    $ cat
host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/pkgconfig/glesv2.pc
    prefix=/usr
    exec_prefix=${prefix}
    libdir=${exec_prefix}/lib
    includedir=${prefix}/include

    Name: glesv2
    Description: ARM Mali implementation of OpenGL ESv2
    Version: 2.0
    Requires:
    Libs: -L${libdir} -lGLESv2 -lGLESv1_CM
    Cflags: -I${includedir}


For rpi-userland:

    $ cat
host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/pkgconfig/glesv2.pc 
    prefix=/usr
    exec_prefix=${prefix}
    libdir=${exec_prefix}/lib
    includedir=${prefix}/include

    Name: glesv2
    Description: RasberryPi implementation of OpenGL ESv2
    Version: 2.0
    Libs: -L${libdir} -lGLESv2
    Cflags: -I${includedir}/


Did not see where the different linking comes from...

Regards,
Peter
