Library conflict with Xcode

Hi,

When we read the following error message that Xcode 1.5 reports
when trying to build ARAnyM <http://aranym.sourceforge.net/>
under OSX.3.9 :

ld: /usr/lib/gcc/darwin/3.3/libstdc++.a(functexcept.o) illegal reference
to symbol:  std::logic_error::logic_error(std::basic
_string<char,
std::char_traits<char>, std::allocator<char> > const&) defined in
indirectly referenced dynamic library /usr/lib/libstdc++.6.dylib

We can see it tells that there's a conflict at linking stage
between the "libstdc++.a" and "libstdc++.6.dylib" libraries.

But these libraries are similar. It is the static and dynamic
versions of the same library.

Since a recent period (I met this error Feb 7th 2006) there was
no such errors. There's so now a modification of the libraries
handling with Xcode 1.5.

Why does Xcode complains now about simultaneous usage of static and
dynamic versions of the same libraries ? I don't know.

My building system is broken.

This example is given with ARAnyM. But I could give the same
example with K3DSurf <http://k3dsurf.sourceforge.net/> that
fails with the same linking errors. There's now a conflict
between static and dynamic versions of libraries with Xcode ...

Might it be also a recent update of "/usr/lib/libstdc++.6.dylib"
that generates incompatibilities with Xcode 1.5 under OSX.3.9 ?

Can someone help ?

Thanks,

Try posting your question on Apple's developers forum. You can get to it
via http://www.apple.com

Before posting this question here, I first posted it to a mailing list
at <xcode-users@lists.apple.com> without any clear answer so far :(

Are you thinking about another appropriate place I should ask this ?

Found this via Google:

Since Quicktime was updated recently, it may be the reason for your
recent lib problems.

The problem is now fixed for me.

We talked with Martin on an Apple ML about the problem, and we
found the solution. The solution is to downgrade from QT7.0.4 to
QT7.0.3, because Xcode 1.5 is incompatible with QuickTime 7.0.4.

This is important to diffuse the solution, because it's hard to guess.
