When python performs a cross compile, it uses a host interpreter to run steps on behalf of the foreign architecture to finalize the build. When performing these steps, foreign modules may be loaded if the SOABI matches that of the host. This can lead to issues if the modules are linked against a libc not available on the host or if the binaries include instructions unsupported by the host. For now, patch the foreign libraries out of PYTHONPATH and explicitly define the path to sysconfigdata so builds can complete without error. This method currently passes all upstream CI pipelines [0] and should also work (with some modifications) for the migration to 3.12 [1].

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.
