Ruby can't link with MS C runtime (msvcr90.dll)

Question

Hi folks.

I was attempting to run the Ruby Thin demo application on Windows/XP when I got an error that Windows couldn't find "msvcr90.dll" for Ruby 1.8.7 -- I found a redistributable and put that in my path to be confronted with the information that:

"R6034 ... application has made an attempt to lead the C runtime incorrectly"

Earlier today I ran a few eventmachine demos oK, so I am thinking that the problem is with Thin.

The Ruby stack dump isn't that helpful ... (included below). Is there a cure?

I've looked over the other MSVCR90.DLL posts, none of those cures work. The MSVCR90.DLL is now in system32 -- With the "incorrectly linked" error.

Thanks in advance.

appears to be that you need to exclude the /MD parameter and make sure your library calls xfree, not free :)
