I was curious about the 'setenv MACOSX_DEPLOYMENT_TARGET 10.5' I changed it to 10.6 and the original linker errors were resolved. I changed it to 'compiler default' and 10.6 and in both cases got

ld: library not found for -lcrt1.10.6.o

If anyone has gcov working for an iPhone project with gcov enabled under 10.6 - I'd love to see your config.

I have an iPhone 3.0 project.

Compiling with GCC 4.2, targeting iPhone SDK 3.0

I did create a standalone Cocoa app using GCC 4.2 and 10.6 SDK and it links fine..

thanks

I moved a project over to my newly installed Snow Leopard box

My default debug targets use gcov. (-lgcov

I get a link error on Xcode 3.2

_vproc_transaction_end referenced from _gcov_exit in libgov.a
and

_vproc_transaction_begin referenced from _gcov_init in libgcov.a

Symbols not found

Which compiler, which SDK? Try with gcc 4.2 and 10.6 SDK (ie: the
system defaults).
