ich vor kurzem installiert GCC 4.7.3 und GDB 7.6 auf meinem OS X 10.7 System über MacPorts der Lage sein, C++ 11-Code zu kompilieren. Ich kann Apples selbstgemachten clang ++ und gdb nicht verwenden, da es mir nicht erlaubt, den Code der Standardvorlagenbibliothek richtig zu debuggen (wenn ich beispielsweise einen Listeniterator dereferenziere, stürzt das Programm ab).gcc 4.7.3 und GDB 7.6 auf Mac - seltsame Schritt Probleme

Jetzt, mit der neuen GCC/GDB Kombination, habe ich einige seltsame Probleme beim Einstieg in Funktionen. Nehmen Sie dieses minimal Beispiel:

#include <stdio.h> 

class A { 
public: 
    virtual void testMethod() { 
     printf("test in A\n"); 
    } 
}; 

void test(A &a) { 
    printf("asdf\n"); 
    a.testMethod(); // here, stepping works with -std=c++11 
} 

int main() { 
    A a; 
    a.testMethod(); 
    test(a); 
    a.testMethod(); 
    return 0; 
} 

Wenn ich den Code mit g++ -O0 -ggdb test.cpp kompilieren, GDB nicht in A::testMethod überhaupt Schritt ist. Ich kann einen Haltepunkt setzen, indem ich die Codezeile innerhalb von A::testMethod festlege, aber nicht durch Angabe des Methodennamens (b A::testMethod()).

Komischerweise, wenn ich mit g++ -O0 -ggdb -std=c++11 test.cpp kompilieren, tritt GDB in testMethod, wenn von void test() aufgerufen. Stepping funktioniert immer noch nicht. Jetzt kann ich jedoch einen Haltepunkt festlegen, indem Sie nur den Methodennamen angeben.

Weiter, sobald ich das Programm in GDB starten, bekomme ich GDB Warnungen, wie in verwandten Fragen beschrieben. Diese Warnungen erscheinen unabhängig davon, ob ich -std=c++11 oder nicht angeben.

Ich bin mir bewusst, folgende Fragen: Debugging Problems, Weird GDB messages, GDB error message, GDB fails on Mountain Lion, doch sind sie nicht mir geholfen hat. Die Angabe -gdwarf-2 -gstrict-dwarf hilft auch nicht.

-EDIT- Die Ausgabe von nm ist in beiden Fällen gleich:

hat es geschafft, jemand GCC 4.7 und einige entsprechende Debugger arbeiten auf OS X Lion zu bekommen?

hat eine lösung gefunden? Ich habe sehr ähnliche Probleme (http://stackoverflow.com/questions/22581645/gdb-7-7-does-not-step-in-o-on-x-mavericks-with-gcc4-7-3-macports)) – Denis

Nein, tut mir leid. Ich gab schließlich auf. – Entropia

Ich habe versucht, so zu kompilieren .... Es funktioniert gut .... Könnten Sie nur mit -g Option allein versuchen?

Zum Beispiel: g ++ -g test.cpp -o test

Leider hilft das nicht. Das Ergebnis ist das gleiche wie beim Kompilieren mit -ggdb. Wie haben Sie GCC/GDB installiert? – Entropia

Es tut mir leid .... Ich habe Ihren Code in GCC 4.5.3 für CYGWIN versucht. hast du den Befehl nm in der Binärdatei versucht, um zu sehen, ob die Symbole existieren? –

+2

Ich fügte der Frage die 'nm'-Ausgabe hinzu. Ich bin nicht sehr vertraut mit 'nm', aber ich denke, die Symbole sind vorhanden. Zumindest vervollständigt die Registerkarte GDB sie. Außerdem glaube ich nicht, dass es ein allgemeines GCC/GDB Problem ist, eher ein Problem auf Mac. Unter Ubuntu funktioniert alles gut. – Entropia
