i.MX 8M+: error building kernel tools with yocto-generated toolchain

[ianb]

I'm running into build errors when I try to compile the kernel tools with a toolchain I created via Yocto for the i.MX 8M+ eval kit. I'm able to build the device tree, the kernel, and modules; it's just the tools that are failing. Specifically spidev_test. The toolchain was generated via `bitbake <image> -c populate_sdk` as per the i.MX Yocto docs, and has been working fine otherwise.

Here's what I'm seeing:

$ source /opt/fsl-imx-xwayland/6.6-scarthgap/environment-setup-armv8a-poky-linux
$ make tools/spi
  DESCEND spi
  CC      /home/ian/build/imx-yocto-bsp/linux-imx/tools/spi/spidev_test.o

    9 | # include_next <stdint.h>
      |                ^~~~~~~~~~

I can bypass this by adding `-I/opt/fsl-imx-xwayland/6.6-scarthgap/sysroots/x86_64-pokysdk-linux/usr/include` to CFLAGS, but then I run into this:

  DESCEND spi

    7 | # include <gnu/stubs-32.h>
      |           ^~~~~~~~~~~~~~~~

I see that the toolchain is (incorrectly?) linking to stubs-32 and hack in a link to stubs-64 (arm64 target). When I try again, I get this:

It looks like something isn't set up right within the toolchain. Or, am I missing something in my system environment? Any clues as to what's happening here?

Ah, that checks out! My custom image is a variant of `imx-image-multimedia`; I haven't built `full-image`. Thanks!

Hello,

It looks like you have to build the full-image to compile this since for some reason I received stubs-32-bit and for full-image stubs64.
