The following dependency:
depends on !BR2_TOOLCHAIN_USES_UCLIBC || BR2_TOOLCHAIN_HEADERS_AT_LEAST_5_1
was added by commit d63e207eb8, which
bumped python3 from 3.12.9 to 3.13.2.
The commit message doesn't state it, but this dependency was introduced
because uClibc without time64 support (i.e. with kernel headers < 5.1)
causes a runtime assertion in Python [1]:
OverflowError: timestamp too large to convert to C PyTime_t
The problem is that this dependency has not been propagated to reverse
dependencies, causing this kind of kconfig warnings:
WARNING: unmet direct dependencies detected for BR2_PACKAGE_PYTHON3
Depends on [n]: BR2_USE_WCHAR [=y] && BR2_USE_MMU [=y] && BR2_TOOLCHAIN_HAS_THREADS [=y] && !BR2_STATIC_LIBS [=n] && (!BR2_TOOLCHAIN_USES_UCLIBC [=y] || BR2_TOOLCHAIN_HEADERS_AT_LEAST_5_1 [=n])
Selected by [y]:
- BR2_PACKAGE_AVOCADO [=y] && BR2_USE_WCHAR [=y] && BR2_USE_MMU [=y] && BR2_TOOLCHAIN_HAS_THREADS [=y] && !BR2_STATIC_LIBS [=n]
- BR2_PACKAGE_LIBSIGROKDECODE [=y] && BR2_USE_WCHAR [=y] && BR2_TOOLCHAIN_HAS_THREADS [=y] && BR2_USE_MMU [=y] && !BR2_STATIC_LIBS [=n]
- BR2_PACKAGE_OPKG_UTILS [=y] && BR2_PACKAGE_BUSYBOX [=y] && BR2_USE_MMU [=y] && BR2_USE_WCHAR [=y] && BR2_TOOLCHAIN_HAS_THREADS [=y] && !BR2_STATIC_LIBS [=n]
However, propagating this dependency to all reverse dependencies of
python3 would be pretty annoying, especially as the dependency is kind
of "clunky". A configuration with uClibc and kernel headers < 5.1 is
such a corner case that it does not merit such complexity.
A later commit will check for this corner case at build time (while
allowing it in the .config). For now, already drop the dependency in
Config.in.

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
