Thanks!

Then there is still a problem with odroid-mali, because with the
rpi-userland OpenGL ES/EGL provider, libepoxy builds just fine. Try the
following defconfig:
BR2_arm=y
BR2_cortex_a8=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_RPI_USERLAND=y
BR2_PACKAGE_LIBEPOXY=y
# BR2_TARGET_ROOTFS_TAR is not set
I've tested your patches, and indeed I've been able to reproduce this
issue. It's because they have re-used the mesa3d headers as-is it
seems, and therefore MESA_EGL_NO_X11_HEADERS needs to be defined when
X11 is not used.
So I guess this would need to be adjust in the pkg-config files
installed by odroid-mali... even though that will only work with the
packages that then use pkg-config to detect OpenGL ES/EGL.
Adding in Cc Peter Seiderer, who also mentioned MESA_EGL_NO_X11_HEADERS
in another thread recently.
Best regards,
Thomas
