[New-bugs-announce] [issue44245] Cross-compilation of CPython 3.8 with _socket module using Anddroid NDK fails

[Ladislav Heller]

New submission from Ladislav Heller <ladislav.heller at gmail.com>:

Trying to cross-compile CPython 3.8 using Android NDK toolchain with _socket module enabled. Build fails at:

../Modules/socketmodule.c:6739:5: error: invalid use of undefined type 'struct if_nameindex'
     for (i = 0; ni[i].if_index != 0 && i < INT_MAX; i++) {
     ^
../Modules/socketmodule.c:6739:19: error: dereferencing pointer to incomplete type
     for (i = 0; ni[i].if_index != 0 && i < INT_MAX; i++) {
                   ^
../Modules/socketmodule.c:6753:17: error: invalid use of undefined type 'struct if_nameindex'
                 ni[i].if_index, PyUnicode_DecodeFSDefault, ni[i].if_name);
                 ^
../Modules/socketmodule.c:6753:19: error: dereferencing pointer to incomplete type
                 ni[i].if_index, PyUnicode_DecodeFSDefault, ni[i].if_name);
                   ^
../Modules/socketmodule.c:6753:17: error: invalid use of undefined type 'struct if_nameindex'
                 ni[i].if_index, PyUnicode_DecodeFSDefault, ni[i].if_name);
                 ^
../Modules/socketmodule.c:6753:62: error: dereferencing pointer to incomplete type
                 ni[i].if_index, PyUnicode_DecodeFSDefault, ni[i].if_name);
                                                              ^

Without _socket module, the cross-compilation works well. Also the result python3 build transferred to my Android device and tested in Terminal app works well. However without _socket module for example the command:
"python3 -m ensurepip"
obviously fails because of missing _socket module.
