<div>Hey,</div>
<div> </div>
<div>Not entirely sure this is the right place to ask this question, but it’s all I’ve found, and there is a page here about debug support.</div>
<div> </div>
<div>I’m using XCode 4.6.3 on Mac. When I build my C++ project with _LIBCPP_DEBUG2 set to 1, I get linker errors like these:</div>
<div> </div>
<div>"std::__1::__libcpp_db::__comparable(void const*, void const*) const", referenced from:</div>
<div> NSString* (anonymous namespace)::dump<double>(NSString*, double*, int vector[4]) in vMAT_Array+UnaryOps.o</div>
<div> NSString* (anonymous namespace)::dump<float>(NSString*, float*, int vector[4]) in vMAT_Array+UnaryOps.o</div>
<div> signed char (anonymous namespace)::isEqualEpsilon<double>(double*, int vector[4], double*, int vector[4], double) in vMAT_Array+BinaryOps.o</div>
<div> signed char (anonymous namespace)::isEqualEpsilon<float>(float*, int vector[4], float*, int vector[4], double) in vMAT_Array+BinaryOps.o</div>
<div> "std::__1::__libcpp_db::__dereferenceable(void const*) const", referenced from:</div>
<div> NSString* (anonymous namespace)::dump<double>(NSString*, double*, int vector[4]) in vMAT_Array+UnaryOps.o</div>
<div> NSString* (anonymous namespace)::dump<float>(NSString*, float*, int vector[4]) in vMAT_Array+UnaryOps.o</div>
<div> signed char (anonymous namespace)::isEqualEpsilon<double>(double*, int vector[4], double*, int vector[4], double) in vMAT_Array+BinaryOps.o</div>
<div> signed char (anonymous namespace)::isEqualEpsilon<float>(float*, int vector[4], float*, int vector[4], double) in vMAT_Array+BinaryOps.o</div>
<div> </div>
<div>Seems like I need to link in a different lib or something, but darned if I can figure out what. Any ideas?</div>
<div> </div>
<div>This question was asked on StackOverflow (by someone else) in April and has gone unanswered.</div>
<div> </div>
<div>Thanks,</div>
<div> </div>
