I'm work with Debian 11 and Ruby 3.0.6 It's a MV with the Bitnami's preintallation of Redmine: https://bitnami.com/stack/redmine/virtual-machine
But I'm tring to change the database MariaDB to usa an external SQL Server. To do this, I need install the gems tiny_tds, activerecord-sqlserver-adapter.
When I try to install it, it returns this error (no matter which gem you want to install, it returns the same error):
bitnami@debian:~$ sudo gem install tiny_tds
Building native extensions. This could take a while...

I'm tied to install ruby-dev and gcc (sudo apt-get install gcc ruby-dev).
Also I'm tried to install ubuntu-dev-tools (sudo apt-get install ubuntu-dev-tools).
With no results.
Your mkmf.log says
/usr/bin/ld: cannot find -lz
It misses zlib. Try
apt install zlib1g-dev
