Question: how do one solve unsatisfiable constraints that require both *ssl* libs?
EDIT (17h after): ~ # apk add openssl-dev qt-dev
ERROR: unsatisfiable constraints:

Can you provide a reproducer?
This works for me...

Dockerfile:
FROM gliderlabs/alpine:3.6
RUN apk add --no-cache openssl-dev qt-dev
alpine linux packages, including qt-dev related packages, are compiled with libressl, not openssl.
openssl-dev and libressl-dev provide many files that have the same path, therefore the two packages cannot be installed at the same time.
example for /usr/lib/libssl.so: https://pkgs.alpinelinux.org/contents?file=libssl.so&path=&name=&branch=v3.6&repo=&arch=x86_64
more info:
- the issue to migrate from openssl to libressl is here.
- It was also announced on the mailing list here.
hth.
Can you give an example of what you are building that needs openssl-dev if this is not yet solved?
@andyshinn sure. I'm building gr-gsm with PyBOMBS under Alpine. Basically a RUN that should go smooth like:
apk --update add --no-cache --virtual build-deps $DEPS
printf "[list]\nformat=columns\n" >> /etc/pip.conf
pip install PyBOMBS
pybombs auto-config
pybombs recipes add-defaults
pybombs prefix init ./gnur -a gnur
pybombs -p ./gnur install gr-gsm
ldconfig
@jumanjiman regarding on the mailing list email I see "you will have to replace
it with", since the objetive is to have /usr/lib/libssl.so didn't it makes sense to have some sort of meta-package linking with names for eg. libssl or libssl-dev ? That would increase redundancy and smooth-upgrading to future versions of Alpine.
ps: I don't know Apk nor Alpine's from a developer point of view, so I don't know if it's already implemented.
Apk are giving me these errors also.

After 5 days on this I am tired of my CPU's performance already. This is the actual state of my gr-gsm.Dockerfile @andyshinn
for anyone else running into issues building Python3.7 on alpine, eg:
Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381
make sure you update to the latest alpine release. if you have FROM alpine:3.8, you get a recent enough version of libressl-dev, and Python will build fine.
