Subject: [alpine-devel] py3-cx_freeze not compatible with python3.7 on alpine 3.10rc1

cx_freeze v5.1.1 is not compatible with python3.7, so the py3-cx_freeze =
package won=E2=80=99t work in alpine 3.10.

Here a test with alpine 3.10rc1, that works fine with alpine 3.9 (and =
it=E2=80=99s python 3.6):=20

~ # echo 'print("Hallo world!")' > hello.py
~ # python3 hello.py
Hallo world!
~ # cp -p /usr/bin/ldd .
~ # cxfreeze hello.py
=E2=80=A6 lots of output ...
~ # dist/hello
Fatal Python error: initfsencoding: Unable to get the locale encoding
ImportError: invalid flags 1556882925 in 'encodings'

Current thread 0x00007f8e2c36fd48 (most recent call first):
Aborted
~ #=20

Three alternatives come into my mind:
- drop cx_freeze
- patch cx_freeze v5.1.1, =
https://github.com/msys2/MINGW-packages/commit/4c18633ba2331d980f00aff075f=
17135399c43c5 might help, but I haven=E2=80=99t tested it.
- use the cx_freeze beta version 6.0b1, but I have no idea what issue =
that version has

BTW: The ldd program (in all alpine versions) creates invalid output in =
case you use it on a library, here an example:

~ # ldd /lib/libssl.so.1.1=20
	ldd (0x7ffb49916000)
	libcrypto.so.1.1 =3D> /lib/libcrypto.so.1.1 (0x7ffb49618000)
	libc.musl-x86_64.so.1 =3D> ldd (0x7ffb49916000)

The loader ld-musl-x86_64.so.1 and libc.musl-x86_64.so.1 point to "ldd", =
what's totally wrong. That's why you have to copy the ldd binary to your =
current directory before using cx_freeze.

Here my alternative ldd, it works much better with cx_freeze (and =
pyinstaller):
#!!/bin/sh
exec /lib/ld-musl-* --list -- "$@"

Here an example, with more reasonable results:
~ # ldd.new /lib/libssl.so.1.1
	/lib/ld-musl-x86_64.so.1 (0x7fa671495000)
	libcrypto.so.1.1 =3D> /lib/libcrypto.so.1.1 (0x7fa671197000)
	libc.musl-x86_64.so.1 =3D> /lib/ld-musl-x86_64.so.1 =
(0x7fa671495000)
