Unlike libgpiod2, this version of libgpiod relies on the deprecated GPIO
ABI version 1. This ABI used to be enabled by default. However, since
Linux 7.1-rc1 (commit 7673e4c7f7f9 "Do not enable the v1 uAPI by
default"), this is not the case anymore. Failing to enable the ABI
results in a non-functional libgpiod. For instance:
# gpioinfo
gpioinfo: error creating line iterator: Invalid argument
Fix this by enabling the ABI v1 in LIBGPIOD_LINUX_CONFIG_FIXUPS.

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 https://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
