Since upstream commit [1] the original v4l2loopback-ctl bash script was
replaced by a C version, so add a proper compile step (and remove bash
runtime dependency) to fix '[help] v4l2loopback package build fails for
raspberrypi5' [2].
The issue can be reproduced with the commands:
cat <<EOF >.config
BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG=y
BR2_PACKAGE_V4L2LOOPBACK=y
BR2_PACKAGE_V4L2LOOPBACK_UTILS=y
EOF
make olddefconfig
make v4l2loopback
Note: upstream commit [1] was introduced in version v0.13.0.
Buildroot bumped v4l2loopback to v0.13.2 in [3].
Fixes:
/usr/bin/install: cannot stat
'.../build/v4l2loopback-0.13.2/utils/v4l2loopback-ctl':

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
