I'm getting the following error when trying out 2020.02 with the latest musl-based toolchain
/build/host/bin/x86_64-buildroot-linux-musl-gcc -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -std=c99 -Wextra -Wno-unused-result -Wno-unused-parameter -Wno-missing-field-initializers -Werror=implicit-function-declaration -I./Include/internal -I. -I./Include -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -fPIC -DPy_BUILD_CORE_BUILTIN -c ./Modules/xxsubtype.c -o Modules/xxsubtype.o

| ^~~~~~~~~~~~~~~

Has anyone else seen this?

Python or python3? Could you provide a .config or defconfig file
for the failure?

python3, defconfig attached. This config has been working with 2019.02, I loaded and re-saved it

Hello Simon,

Given defconfig still compiles fine here....
- ./build/python3-3.8.2/Modules/posixmodule.c:
The usage of copy_file_range() is protected by HAVE_COPY_FILE_RANGE
- HAVE_COPY_FILE_RANGE is defined in pyconfig.h:
$ grep HAVE_COPY_FILE_RANGE build/python3-3.8.2/pyconfig.h
#define HAVE_COPY_FILE_RANGE 1
- the buildroot compiled musl libc proviedes copy_file_range:
$ nm -A host/x86_64-buildroot-linux-musl/sysroot/lib/libc.so | grep copy_file_range
host/x86_64-buildroot-linux-musl/sysroot/lib/libc.so:000000000001f4bd T copy_file_range
- the header file provides copy_file_range() (protected by _GNU_SOURCE)
$ grep copy_file_range host/x86_64-buildroot-linux-musl/sysroot/usr/include/unistd.h
ssize_t copy_file_range(int, off_t *, int, off_t *, size_t, unsigned);
Please try a plain defconfig (without EXTERNALs), make sure no additional patches/config files
are used.....otherwise out of ideas...
Regards,
Peter
