Docker-alpine: installing openssl-dev and openldap-dev in alpine:3.6 not possible due to unsatisfiable contstraints

[sebastianhutter]

Installation of openssl-dev and openldap-dev in alpine:3.6 and alpine:3.5 is not possible due to unsatisfiable contstraints:

# docker run --rm -ti alpine:3.6 apk add --no-cache openssl-dev openldap-dev
fetch http://dl-cdn.alpinelinux.org/alpine/v3.6/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.6/community/x86_64/APKINDEX.tar.gz
ERROR: unsatisfiable constraints:

this works in alpine:3.4:

# docker run --rm -ti alpine:3.4 apk add --no-cache openssl-dev openldap-dev

I assume some dependencies in the APK repository are off. Any ideas to circumvent this issue?

This sounds like openldap is built against libressl instead of openssl in 3.6. You cannot install both openssl-dev and libressl-dev in 3.6. What are you needing openssl-dev for? Depending on what you are building, libressl-dev may be able to replace openssl-dev.

i need compile nginx from source with ssl and ldap.
libressl-dev did the trick. thanks a lot for pointing this out!

I do have the same problem. And libressl-dev does not do the trick :(

[sebastianhutter]

@juliengk what are you trying to build which causes trouble? can you post your dockerfile / commands?

I have tried again to replace openssl-dev with libressl-dev and that worked. When building the docker image, some python packages are installed and so was complaining about the missing lib. I have updated the version of the python packages and all is good now.

Thanks and sorry for disturbing for nothing
