Subject: c-extension problem


Dear list.

After reading through this walkthrough (1) of compiling c-extensions on
Windows I was finally able to build the pickaxe example on two different
PC's. One with Visual Studio 2003, the other with Visual C++ express 2005.
Both compiled, only one worked. This raises some issues.

I) Should I try to fix this? I mean, will working with C-extensions bring
   me down the road of never-ending versioning/library/compiler/... 
   problems.

II) If yes, how to fix the technical issues at hand today?

Any suggestions would be very welcome.

Anyway, here's what happened.


Building on VS 2003 gave a working result at first try. C++ express 2005
however gave two distinct errors when running



irb: require 'Test'

GUI warning-box:
   ruby.exe - Unable to Locate Component
   This application has failed to start because MSVCR80.dll was not found. 
   Re-installing the application may fix this problem.

irb: Load error 126 ...



After searching from mscvr80.dll, finding it here(2) and copying it to 
c:\windows\system32 the following error appeared:

irb: require 'Test'

GUI warning-box
   Microsoft Visual C++ Runtime Library
   Rumtime Error!
   Program: c:\progra~1\ruby\bin\ruby.exe
   R6034
   An application has made an attempt to load the C runtime library 
   incorrectly
   Please contact the application's support team for more information.

irb: Load error 1114...


All the best
