Build fail on Alpine Linux

[pdfrod]

Never tried ruby-install, I'm using rbenv. I don't even get to the part where I can install gems, as the error happens when installing Ruby.

isinf and isnan are present in https://github.com/docker-library/ruby/blob/2d6449f03976ededa14be5cac1e9e070b74e4de4/2.3/alpine/Dockerfile

I have no issue installing unf_ext 0.0.7.2 out of alpine:3.4

/opt/smoke # ruby --version
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux-musl]
/opt/smoke # bundle show unf_ext 
/usr/lib/ruby/gems/2.3.0/gems/unf_ext-0.0.7.2

same pb here with alpine 3.5

I'm having the same issue with Alpine 3.6.

I was able to workaround the issue adding the environment variables ac_cv_func_isnan=yes ac_cv_func_isinf=yes as explained here: gliderlabs/docker-alpine#261 (comment)

Did any of you by any chance install Ruby with ruby-install? I'm seeing this on alpine:3.6 but on the eventmachine gem, using Ruby 2.2.9.

Managed to build a good version of Ruby 2.2.9 on Alpine 3.6 with the following Dockerfile:
