Ok, so last time I installed Ruby, Rails and RMagick under Cygwin I had the ever so common fork problem which I solved with rebaseall. Now I’m 4500 miles from home on another computer (my Sister’s laptop) and I’ve got a whole new problem going on. At first I thought this may be something to do with Mongrel, but the error only occurs when Im using RMagick. The reason I think this is a different error, is because instead of complaining about the RMagick dll, it’s complaining about ruby/gems/1.8/mongrel-1.0.1/lib/http11.so… and I really don’t understand what’s going on now. I’ve tried rebaseall again, to no avail. I’ve also tried remapping at a couple of different addresses and I just can’t get it working. I’ve spent the last couple of hours trying to figure this out, and I rarely ask for help unless I have to. If anyone could shed some light on this I’d be very much obliged. The error is as follows: [main] ruby 57788 C:\cygwin\bin\ruby.exe \*\*\* fatal error \*\*\* - unable to remap C:\cygwin\lib\ruby\gems\1.8\gems\mongrel-1.0.1\lib\http11.so to same address as parent(0x2C0000) != 0x1C760000 I’ve tried reinstalling both RMagick and Mongrel and nothing changes. I also tried rebasing http11.so, which resulted in garbage on the console and a few PC speaker beeps. Anyone able to assist? Thanks in advance… Cliff ---

Bump. Also, it’s definitely something to do with Mongrel and not specifically RMagick, since using WEBrick won’t replicate this error.
