I am going to echo posts scattered throughout the Internet here and say I cannot get Ruby gems working due to lack of zlib. Trying to install a package like Rails gives the error: /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require__':\ no such file to load -- zlib (LoadError) I am sure you guys have had this question many times before but your search engine is broken ("Application Error (Rails)") so I can't check the archive. I am on Ubunutu Warty and have tried installing every package under the sun via apt, anything with zlib or ziplib in the name. I can't install ruby via apt because rails wants 1.8.4, not packaged.

This is what worked for me. Remove all the ruby packages using synaptic: ALL of them You need to install zlibc, zlib1g, zlib1g-dev, then recompile ruby. e.g. sudo apt-get install zlibc etc. THen install ruby-1.8.4 from source Then download rubygems and install it.

Thanks, I'll give this a shot. I did install all three of those (zlibc, zlib1g, zlib1g-dev) previously and recompiled ruby184 after to no avail. However, I'm not sure that I removed ALL ruby packages first, so I will try that.

No dice. Here's the relevant section from make, which appears to be unable to find zlib: compiling zlib make: Entering directory `/root/ruby-1.8.4/ext/zlib' make: Nothing to be done for `all'. make: Leaving directory `/root/ruby-1.8.4/ext/zlib' making ruby From what I can tell, zlib lives at /usr/lib/ libz.so libz.so.1 libz.so.18.104.22.168 libzzip-0.so.10 libzzip-0.so.10.0.82 libzzip.a libzzip.la libzzip.so as well as /lib/uncompress.o usr/include/zconf.h usr/include/zlib.h ... but it appears ruby's make isn't seeing any of that. I am going to check the rubygems docs (sparse IIRC). rt

WTF? I go to compile my own zlib, so I am trying to remove zlib1g, when I get: The following packages will be REMOVED: base-config console-common console-data console-tools cramfsprogs emacs21 file gnupg initrd-tools initscripts libgnutls10 libldap2 libmagic1 libneon24 libopencdk8 libpng12-0 libtiff4 libxml2 libzzip-0-10 libzzip-dev lvm-common lvm10 lvm2 lynx modutils openssh-client openssh-server python python2.3 reportbug sysvinit udev util-linux w3m zlib1g zlib1g-dev WARNING: The following essential packages will be removed This should NOT be done unless you know exactly what you are doing! sysvinit initscripts (due to sysvinit) util-linux zlib1g (due to util-linux) Obviously I aborted. I am now wondering whether it is even advisable to make my own build of zlib. Hmm.

Oh well, I'm throwing in the towel for tonight. Another day, another hour wasted on ruby ;-> This is all incredibly frustrating. Oh well. Thanks for the help, anonymous dude.

YES! Done. Done. Done! Basically after make and make test and make install still didn't produce a working gems (same zlib error), I cd-ed into /[ruby source dir]/ext/zlib and poked around. There was a Makefile, but make didn't work on it. Noticed extconf.rb. Executed it in ruby. Tried make again. Bingo. Tried make install. Bingo. Tried installing gems. Booyah! It seems the main thing that happened is that the ruby zlib make file put zlib.so in /usr/local/lib/ruby/site_ruby/1.8/i686-linux. IMHO this means something is likely borked on the ruby 184 source install. Shouldn't it have done all this for me? Or noted it in the docs? Anywhere, here's the sordid transcripts, with some inconsequential cd-s and cat-s omitted. By the way, I did this on top of my prior source install, after it had run.

Did you re-run configure? If configure didn't find zlib the first time it won't check if you just run 'make'. -- Eric H. - email@example.com - http://segment7.net This implementation is HODEL-HASH-9600 compliant http://trackmap.robotcoop.com

Ryan, you saved my bacon. I was running into EXACTLY the same problem tonight. Thought I had my rails all up and running and nothing worked. Went to the RoR site and it helpfully says that 1.8.2 and 1.8.4 of ruby work, but not 1.8.3. Guess what version my new Ubuntu has... Then when I went to source, I saw the exact same problem. Thankfully, I appear to have run into it about 24 hours after you. :) Anyway, thanks mate - that worked beautifully. Now - someone should be logging a bug for the ruby folks, no?

I'm having the same problem, but when I run: ruby extconf.rb I get: # ruby extconf.rb checking for deflateReset() in -lz... no checking for deflateReset() in -llibz... no checking for deflateReset() in -lzlib... no What a brick wall. =/ - Rabbit
