As reported by Antoine Coutant on the Buildroot mailing list [1]: rpds depends on the crate pyo3. This crate uses "std::sync::atomic::AtomicI64" which doesn't exist for 32 bits targets. That leads to an error as reported by Buildroot Gitlab-ci. An issue have been opened on pyo3's github [2]. A fix have been accepted by pyo3 [3] and merged in pyo3 0.20.3 release [4]. This pyo3 0.20.3 uses crate portable-atomic [5] to provide atomic types and compare and swap operations for all targets that can use std. python-rpds-py 0.18.1 is the first release that use pyo3 0.20.3. Before python-rpds-py 0.18.1 release fixing this issue would require that we be able to patch a package during the Cargo vendoring step [6].

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.
