Rvm / gem install not working (zlib issue) on ubuntu

Hi

gem install is not working under rvm on my ubuntu 10.04 system. The
error is related to zlib.

Note I have followed instructions on stackoverflow related to this and
still come up short.

$ gem install redcar

ERROR: Loading command: install (LoadError)
cannot load such file – zlib
ERROR: While executing gem … (NameError)
uninitialized constant Gem::Commands::InstallCommand

Here is output for zlib on my system

[email protected]:/shared/hbase$ dpkg -s zlib*
Package `zlib*’ is not installed and no info is available.
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.

I am posting here instead of Stackoverflow because posting messages
stopped working for me on SOF, both on FF and in Chrome

Hopefully here this error will be familiar to many and can be answered

have you installed your rvm AFTER you install the zlib?

Hi Hans,
No, I installed rvm first. Not sure why that should matter, but in any
case I have reinstalled rvm . No change.

Hi Hans,
I had already gone through that page and the proposed solutions before,
including reinstalling rvm. Unfortunately they do not work.

Just to be sure, i have followed those directions for the third time.
Still fails. This is extremely frustrating.

I found that I had two “extra” rubies that weren’t getting uninstalled.
When I made sure I had NO rubies installed, then ran the

rvm pkg install zlib
rvm install 1.9.3

and gem installs started working

The solution was buried in the install log: the X11 libraries were not
found. That was a surprise: this window (chrome …) is running on the
machine along with a bunch of other gui apps… i guess there are
additional libraries required for development.

Use ActiveTcl libraries (if available).
Search tclConfig.sh and tkConfig.sh…
Fail to find [tclConfig.sh, tkConfig.sh]
Use X11 libraries (or use TK_XINCLUDES/TK_XLIBSW information on
tkConfig.sh).
Warning:: cannot find X11 library. tcltklib will not be compiled
(tcltklib is disabled on your Ruby. That is, Ruby/Tk will not work).
Please check configure options. If your Tcl/Tk don’t require X11, please
try --without-X11.
Can’t find X11 libraries.
So, can’t make tcltklib.so which is required by Ruby/Tk.

One question. When you reinstall rvm, does it delete the installed
Rubies? I mean, do you then have to reinstall 1.9.2 and 1.9.3? I ask
because this recently happened to a colleague, and the problem was
that zlib needs to be in your system before compiling Ruby.

Jesus.
