[Python-Dev] python3.10rc2 compilation on android/termux/clang12.0.1 fails
I am trying to compile Python3.10rc2 on rather unusual platform (termux on
android). The
gcc version is listed below:
~ $ g++ -v
clang version 12.0.1
Target: aarch64-unknown-linux-android24
Thread model: posix
InstalledDir: /data/data/com.termux/files/usr/bin
I get following warnings and errors:
Python/pytime.c:398:10: warning: implicit conversion from 'long' to
'double' changes value from 9223372036854775807 to 9223372036854775808

if (!_Py_InIntegralTypeRange(_PyTime_t, d)) {
Python/bootstrap_hash.c:141:17: error: implicit declaration of function

^
Python/bootstrap_hash.c:145:17: error: implicit declaration of function

Not sure if this is limitation of the platform or Python codebase needs
fixes.
Thanks

[Python-Dev] python3.10 compilation on OpenBSD: running into ssl issues
Trying to compile python3.10 on openbsd 7.0 on Pi4. It seems to run into
several openssl issue. I have installed openssl as I couldn't find
libreSSL in the package manager.
The configure seems to passthe ssl test.
configure:17559: checking whether compiling and linking against OpenSSL
works
Trying link with OPENSSL_LDFLAGS=; OPENSSL_LIBS= -lssl -lcrypto;
OPENSSL_INCLUDES=
configure:17581: cc -pthread -o conftest conftest.c -lssl -lcrypto
-lpthread -lutil -lm >&5
configure:17581: $? = 0
configure:17583: result: yes
I get following errors:
>> don't know why this happens
