You all know the error. missing require, blah blah. Seriously, nothing new here. here’s the scoop But I found that zlib was missing from the latest ruby version on my Ubuntu. I download and install from source the latest version, and while installing rubygems, it complains of missing zlib! Has anyone else experience this? This is also the case with the version from March, as well. -------------------------------------------------------| ~ Ari “… NOT INTENDED FOR USE IN … NUCLEAR FACILITIES, AIRCRAFT NAVIGATION … LIFE SUPPORT MACHINES” - iTunes EULA ---

In these respects, ruby (specifically, language, library, and user community) does depend on them. Furthermore, these C libraries are usually available on most operating systems, so I find it reasonable to assume their ruby bindings are available. Making zlib (and similar libraries) an additional component that must be found by the user causes confusion and creates a support burden for people who have no idea what to do to fix it. I’ve had various tickets filed against RubyGems because zlib or openssl or rdoc was missing. It isn’t my job to figure out a certain platform requires extra installations just to get basic ruby functionality, nor is it my job to track changes to package names and installer arguments per platform, but I end up being the one who has to deal with it. I would be much happier if everybody’s ruby worked reasonably the same when they installed ruby, no matter the package system. In this case, the problem was missing zlib headers, which falls under the same general category of a support problem foisted onto undeserving project maintainers. ---

It isn’t my job to figure out a certain platform requires I suppose i can imagine your pain. But hey, do up an faq if you really do get that many support requests like that. -jf – In the meantime, here is your PSA: “It’s so hard to write a graphics driver that open-sourcing it would not help.” – Andrew Fear, Software Product Manager, NVIDIA Corporation > **[An Interview With Linus Torvalds: Linux and Git - Part 1 30 Years Of Linux](https://www.tag1consulting.com/blog/interview-linus-torvalds-linux-and-git)** > > Thirty years ago, Linus Torvalds was a 21 year old student at the University of Helsinki when he first released the Linux Kernel.

Yea, well. I’m extra dumb. Apparently the version installed through apt-get contained the zlib package binary for itself only, which is why it threw me for a loop. Needed to install zlib-devel system wide. Fixed! -------------------------------------------------------| ~ Ari crap my sig won’t fit
