Hi, I am using the ruby one click installer all the while. Recently, I tried to compile the latest ruby 1.8.6-p110 and I found it is quite painful to compile it in windows. I am able to compile it with VS2003. I can compile the ruby.exe and rubyw.exe and some standard library without any problem. After compile the ruby.exe, I tried it and it run quite well but when I tried to install rubygems, it start complaining zlib not install. So, I recheck the compile log and found that there are still a lot of ruby extension which is not able to compile in windows because of missing of some library/development header, for eg openssl, zlib, readline, curse, nbm, iconv, pty, tk, syslog..etc . This is no problem for linux coz linux can download all the dev file easily like they can download zlib-dev with linux. However, doing this in windows is hard. For zlib, luckily I can found the source code and compile it successfully. After that, I just install rubygems without any problem. After install rubygems, I fire up IRB and type 'require 'irb/completion''. It complain again no readline ext found... :( I had to start finding any readline source/library for windows available on net. I successful to found it with GNUWin but still not able to compile readline binding for ruby....I read the log file, it will check for ncurse.lib, termcap.lib, curse.lib, edit/readline.h...where do I get all this file???? So, can anyone tell me how to compile readline for ruby in windows? and so for openssl, curse, iconv, tk..... -- Posted via http://www.ruby-forum.com/.
