From: Daniel R Date: 2005-12-03T08:32:32+09:00 Subject: Re: how can I install ruby-xslt ? Ok 1) libm: no problem, ruby already has it installed by default 2) libz (zlib): installed from your url (http://gnuwin32.sourceforge.net/packages/zlib.htm). I ran the executable which created the folder "Program Files\GnuWin32" with following folders: - bin - contrib - doc - include - lib - man - manifest - uninstall The bin folder contains the file "zlib1.dll", which already was existing in the ruby\bin folder from the defeult ruby installation. Anyway, when I start extconf.rb, I still get the error checking for inflate() in z.lib... no 3)libiconv: installed from your URL, seems ok extconf failure: need zlib So installing gnuwin32 zlib didn't help. 4)libxml2: ok, downloaded, unpacked and put to the same folder as libz. SO... I still can't figure how I can make zlib work properly. What is strange is that there was already a file named zlib1.dll in the ruby\lib folder .... anyway, each extconf.rb file I tested gave me the same "need zlib" error There is some progress, but it is still not working. Anyway, thank you again for your help. I hope we will solve all these problems finally.
