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.
