Hello,

Thanks for your patch. I fixed up a few things, wanted to apply... but
it fails to build for me. See below a number of comments, and details
about the build failure.

You need to add an entry to the DEVELOPERS file, like this:

+N:     Mika Westerberg <mika.westerberg@linux.intel.com>
+F:     package/tbtools/

(make sure to respect alphabetic ordering of developers)

I think it was worth adding a comment about this:

+       # Fails to build on 32-bit systems

You need a Config.in comment:

+comment "tbtools needs udev /dev management"
+       depends on BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS
+       depends on BR2_ARCH_IS_64
+       depends on !BR2_PACKAGE_HAS_UDEV

You're missing:

+TBTOOLS_DEPENDENCIES = udev

without which udev is not built before tbtools. Without this, it fails
with a pkg-config detection issue.

But even with udev built before, I get a build failure:

  = note: /home/thomas/projets/buildroot/output/host/opt/ext-toolchain/bin/../lib/gcc/aarch64-buildroot-linux-musl/12.3.0/../../../../aarch64-buildroot-linux-musl/bin/ld: cannot find -ludev: No such file or directory
          collect2: error: ld returned 1 exit status

You can reproduce the following defconfig:

BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_AARCH64_MUSL_STABLE=y
BR2_INIT_NONE=y
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_TBTOOLS=y
# BR2_TARGET_ROOTFS_TAR is not set

Could you have a look and submit a v2 ?

Thanks a lot!

Thomas

I think Rust udev wants to have glibc as the C library. I will add
dependency to that as well.

I'll fix these up in the next version.
