Undefined reference to `dbanydatecrack' while gem install tiny_tds

[rpelorosso]

Hi!

I'm trying to install the tiny_tds Gem.

I have the following Dockerfile:

FROM lambci/lambda:build-ruby2.5
RUN yum -y install freetds
RUN yum -y install freetds-devel

freetds and freetds-devel seem to install without issues, but if I SSH into the container and run

gem install tiny_tds

it fails when compilling tiny_tds :

I would assume that having freetds should suffice, but maybe there's something else I'm missing.

Do you have any ideas for fixing this issue?

Thank you! Rodrigo
