It will be error when I build the kernel separately

I download the source of the kernel from Jetson Linux R32.7.3 | NVIDIA Developer
I build it with the command

make ARCH=arm64 tegra_defconfig
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- LOCALVERSION=-tegra

When I run my run my app, it shows that

nvbuf_utils: Could not get EGL display connection
nvbuf_utils: ERROR getting proc addr of eglCreateImageKHR
nvbuf_utils: ERROR getting proc addr of eglDestroyImageKHR
EGL_EXT_device_base missing

But when I use the kernel that you has built, it works well.
What’s the matter? I need to modify the kernel.

Is Xorg running when you run this app?

I think it’s my mistake. Because my make is 4.3. It must change

the-space :=
the-space +=
// to
E =
the-space +=  $E $E

in the Kbuild.include.
And then make again and works well.
