Re: [ros-users] compile problem nodelet in OSX

Brian, on my machine (10.7) I don't have an archive file (.a) I have .dylib
and it gives this output. This might be something that goes away with Lion.

∫ file /usr/lib/libstdc++.dylib
> /usr/lib/libstdc++.dylib: Mach-O universal binary with 2 architectures
> /usr/lib/libstdc++.dylib (for architecture x86_64): Mach-O 64-bit
> dynamically linked shared library x86_64
> /usr/lib/libstdc++.dylib (for architecture i386): Mach-O dynamically
> linked shared library i386


But even on 10.6 the built-in libstdc++ library should be _at least_ x86_64.
I would expect it to be more likely for you library to be x86_64 only and
lack i386. But all of the built-in libraries on OS X 10.6+ should be
universal (except notably carbon which is deprecated and lacks a x86_64
variant).

Have you replaced your system tool chain possibly with an i386 only version?
If so, or unsure, try reinstalling Xcode?

Hope something in there will help,
