#43001: can not debug (gdb 7.7) programs compiled with gcc 4.7.3 on OSX 10.9.2 XCode 5.1 64bit ------------------------+-------------------------------- Reporter: davydden@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.2.1 Keywords: | Port: gdb, gcc47 ------------------------+-------------------------------- Compile 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; } }}} with macport's gcc 4.7.3: g++-mp-4.7 -g -gdwarf-2 -gstrict-dwarf -O0 prog.cc -o prog Now if I try to debug it: {{{ $ ggdb ./prog GNU gdb (GDB) 7.6 Copyright (C) 2013 Free Software Foundation, Inc.

I saw a lot of similar problems on StackOverflow with slightly different results depending on 64/32 bit, imposing C11, etc. Here are few: [http://stackoverflow.com/questions/20909547/missing-call- stack-frame-with-assert-for-gdb-7-6-on-mac], [https://www.sourceware.org/ml/gdb/2014-02/msg00023.html], [http://stackoverflow.com/questions/10592521/gdb-error-message-gcc-4-7 -from-macports/11705195#11705195] I don't know if the problem is related to GCC or GDB, but i hope there is a solution, since many people experience it and so far I have not seen any way to overcome it... p.s. I have Xcode 5.1 {{{ $ g++-mp-4.7 --version g++-mp-4.7 (MacPorts gcc47 4.7.3_3) 4.7.3 Copyright (C) 2012 Free Software Foundation, Inc. This is free software; see the source for copying conditions.
