NuttX x86_64 (qemu-intel64) builds with the native host gcc, which exposed several host-environment leaks in the CPython cross build: - Pass the -D/-U macro flags from CFLAGS as CPPFLAGS so preprocessor-only configure probes (Misc/platform_triplet.c) do not see the host's __linux__ and misdetect the platform as x86_64-linux-gnu, enabling Linux-only code such as the perf trampoline. - Force linux/random.h and sys/xattr.h probes to no in config.site: NuttX provides neither, but a native toolchain resolves them against the host /usr/include. The former drags host ioctl macros into posixmodule, the latter enables os xattr support with no xattr syscalls to link against. - Disable _curses, _curses_panel, _dbm, _gdbm, _hashlib and _tkinter: their host libraries are discovered via pkg-config when the target compiler can compile host headers. hashlib keeps working through the built-in HACL implementations. - Only build _posixsubprocess when the arch has a real fork(): its vfork() support is only an optimization and the fork() fallback path (PyOS_BeforeFork/PyOS_AfterFork_*) is compiled unconditionally but declared only under HAVE_FORK. This also fixes rv-virt:python, which became vfork-only after the fork/vfork split. Signed-off-by: raiden00pl <raiden00@railab.me> Assisted-by: Claude Code |
