Hi Jon!

I don't know much about using ZeroLink with C++, but I see that there are _numerous_ caveats to using ZeroLink with static initializers covered in the ZeroLink release notes with Xcode (I'm using 2.1). You might want to check these out. Just do a documentation search for ZeroLink and you'll find it quick enough.

There are also some ZeroLink debugging aides that you can turn on.

I suspect that the majority of ZeroLink problems, and possibly the cause of your problem, is an attempt to call a ZeroLink-resolved function very early in your application -- before the ZeroLink facility has been, or can be, initialized.

The other issue could be your subversion of the linker by specifying the statically linked libraries using command-line arguments rather than having them as input files to the Linker phase. It's entirely possible that ZeroLink no longer knows about your libraries, and has no linkage to them at all. This is just a guess, and you'd have to ask the ZeroLink engineers if this would be a problem.
