Undefined symbols when attempting to use CoverStory with iPhone app: _vproc_transaction_end, _vproc_transaction_begin

Question

After following these steps to set up an iphone project with CoverStory, my build fails with two linker errors.

Undefined symbols:
  "_vproc_transaction_end", referenced from:
      _gcov_exit in libgcov.a(_gcov.o)
      _vproc_transaction_end$non_lazy_ptr in libgcov.a(_gcov.o)
     (maybe you meant: _vproc_transaction_end$non_lazy_ptr)
  "_vproc_transaction_begin", referenced from:
      ___gcov_init in libgcov.a(_gcov.o)
      _vproc_transaction_begin$non_lazy_ptr in libgcov.a(_gcov.o)
     (maybe you meant: _vproc_transaction_begin$non_lazy_ptr)
ld: symbol(s) not found
collect2: ld returned 1 exit status

I'm using Xcode 3.2, GCC 4.2 on Snow Leopard. Any ideas what I'm missing?

Answer 1

Did you add "-lgcov" to Other Linker Flags as the Web page directs?

What is the value of the MACOSX_DEPLOYMENT_TARGET setting? This page and this page suggests the value needs to be set to 10.6.

Answer 2

Here's how to get gcov running with Xcode 3.2.2, GCC 4.2 on Snow Leopard:
