Hey all, Wasn’t sure if this should go to the ruby or rails list but here we are… I’ve been running OS X (10.8.4) with the packaged ruby (1.8.2) and rails for some time, no problems. I decided to test out mongrel but that requires \>= 1.8.4 so I grabbed the 1.8.5 source, built that then modified my path and all good… up and running. The problem is all my gems are gone. Well they’re not gone of course but “gem list --local” shows nothing and, of course, nothing that depends on them works. I’ve looked around a good bit but haven’t seen anything about this. Any ideas on why this is? Thanks in advance! Tim Be who you are and say what you feel, because those who mind don’t matter and those who matter don’t mind. - Dr. Seuss ---

In my case 1.8.5 is in /usr/local/… and so the gems are in /usr/local/lib/ruby/gems/1.8/gems/ – your gems won’t be there. You can set the GEM\_HOME environment variable, or re-install your gems. I re-installed. BTW, if you are using gcc4 as shipped by Apple, you should re-compile with -O or -O1 rather than -O2, or use gcc3 – with -O2 you will get strange heap problems after running ruby for a while.

Has a bug been filed on this? Is it unique to Macs, or will any gcc 4 show it? I run Gentoo Linux, Ruby 1.8.5 and gcc 4.1.1. If there are “strange heap problems”, I’d like to be able to reproduce them and get them fixed! ---

Just in case this is of use to anyone else it’s actually GEM\_PATH that needs to be modified.

My understanding is that it was fixed in the very early days of gcc4 but after Apple took their snapshot (gcc 4.0.1). There hasn’t been a patch, at least I’m not aware of a patch. It shouldn’t affect anyone running on linux anymore (it doesn’t affect me on linux). The bug shows up after a few hours to several days of ruby running. It apparently either won’t or is _very_ unlikely to occur in programs running for less time than that (most ruby programs do not run that long, I’m running a Rails in Mongrel application that never stops). Here is a thread that I started last April: \. There are links in that thread to more information about the problem. Cheers, Bob > I run Gentoo Linux, Ruby 1.8.5 and gcc 4.1.1.
