From: Guillaume Bloss Date: 2010-07-30T17:39:08+09:00 Subject: Re: 64 bit ruby installation on 64 bit windows Yes I tried to compile ruby for 64b arch, but there is too many libraries to compile in 64, and at the end, I choose to use 32b version of ruby. If you don't need to install any gems and just for a basic usage, it will work fine, but quickly you would install some gems, thaw will require specific libraries you will need to compile in 64b too, and then you will see that this specific library you will try to compile don't support your compiler or 64b or something like that :s but still if you want to try, I suggest you to don't use the microsoft compiler, since some important library (don't remember wich one) dont support this compiler anymore (that's probably why the rubyinstaller team did not compile new rubyinstaller version with mswin32, but use mingw ...) Of course you will also need to recompile all gems you want to install. -- Posted via http://www.ruby-forum.com/.
