The error returned by ld indicates that it wants to load the library 
file for stdc++.  It should be contained within your standard library 
search path.  Do you have libstdc++-devel installed?  It contains the 
library archive files that ld needs to load (sorry about the 
mis-direction earlier).  It should contain:

I think these are the files ld needs to find.
