[ruby-core:36524] [Ruby 1.9 - Bug #1157] missing zlib.rb?

Issue #1157 has been updated by wei gui.


The error is due to zlib1g-dev is not installed by default. In ubuntu, to solve it:
1. sudo apt-get install zlib1g-dev # to install the dependent zlib
2. cd <ruby-src>/ext/zlib # go to ext/zlib in ruby source directory
2. ruby extconf.rb 
3. make # to generate zlib.so
4. make install

=begin
 I just installed 1.9.1 onto Mandriva 2009 (Linux version 2.6.27.10-desktop-1mnb ([e-mail]) (gcc version 4.3.2 (GCC) ))
 Ran ./configure
 Ran make 
 Ran: gem install rails
 
 And this is what I got:
