Hi Shawn,

I have an existing project (created in Xcode 2.1) that has been

rebuilt everything, manually removed xcode cache directories under
/Library and ~/Library, removed build output directories, etc....
nothing has fixed the issue.
The issue did show up on another developer's system after they
updated
their project so something in the project must be causing this (or
some quirk of externally built libraries).
I am using Xcode 2.2 currently (not yet updated to 2.2.1) on a
10.4.4 system.
Thanks for any ideas on how to correct this issue ...
The problem is quite similar to mine. I'm using Xcode 1.5, and when I
build programs that usually linked fine, there's now problems with
multiple symbols with the "/usr/lib/libstdc++.6.0.3.dylib" from OSX.
3.9.
This happens with 2 softwares that I maintain :
ARAnyM <http://aranym.sourceforge.net/> using SDL 1.2.8
K3DSurf <http://k3dsurf.sourceforge.net/> using QT 3.3.4
There's no solution to it, except that I was told that the stdc++
library may have been altered ... What I'm not convinced about ...
This is currently discussed on this ML.
Actually it is not exactly the same problem as both libraries a
system libraries provided by Apple. A search on the documents for
libSystem comes up with an article about how libSystem is replacing
libraries like libmx. The quick fix is to declare -lSystem for your
targets other link flags. I would like to know why XCode suddenly
starts giving you this warning too. Is a configuration setting for
gcc not set for libSystem as a standard library or is both defined?
Hopefully, somebody else has that answer.

Brian Smith
