Here is a simple program:
#include <iostream> #include <vector> namespace Example { template <int dim> class Problem { public: void run() { std::cout<<"here.."<<std::endl; } }; } int main(int argc, char *argv[]) { Example::Problem<2> problem; problem.run(); return 0; }
compiled with Macport gcc 4.7.3:
g++-mp-4.7 -g -O0 prog.cc -o prog
If I try to debug in gdb 7.7 ( self- compiled, not Macport one!):
$gdb file prog b main r s
I can not enter the function :
34 problem.run(); (gdb) s here.. 36 return 0; (gdb)
Am I doing something wrong? Or does it look like a gdb error when used on os-x mavericks?
UPDATE
I do not see any warnings / errors when using gdb:

I see the same thing as the behavior associated with the call code, as here . Although I was not able to check if compiling with -m32 in my case, since I have everything for 64-bit and, therefore, problems with undefined symbols .
Another issue when debugging here and here, at https://stackoverflow.com/a/165269/169 .
