zlib error while installing gems on Linux

[Joe Cheng]

Pardon my ignorance, I'm not that great with Linux.

I installed Ruby 1.8.2 from source just now, everything went fine. I the=
n
attempted to install gems which seemed to go fine until the end, when I
got a stack trace trying to require zlib[1].

When trying to require zlib from irb, I get:
LoadError: No such file to load -- zlib

I thought maybe I had to install the zlib extension manually so I went
into my ruby-source/ext/zlib and ran extconf, and got this:
checking for deflateReset() in -lz... no
checking for deflateReset() in -llibz... no
checking for deflateReset() in -lzlib... no

I see the appropriate zlib.h and libz.* files in the obvious places
(/usr/include and /usr/lib).

Can anyone point me in the right direction to getting gems fully
installed? Thanks!

Sorry, forgot to mention what version of Linux I am using: Fedora Core 3,
kernel 2.6.9-1.667. Also, gcc version 3.4.2 20041017, zlib 1.2.1.2
20040909. Thanks.

Install zlib-devel by running:
yum install zlib-devel
or=20
up2date zlib-devel
Then run=20
./configure --prefix=3D/usr
make
make install
on Ruby 1.8.2 again. Should work fine.

Woohoo! That worked, once I cleared the stuff out of /usr/local that
resulted from my first attempt at installing Ruby.

Thanks a lot!
