Debugging 32-Bit-Binärdatei in Cygwin-Windows kompiliert mit Mingw-W64

Question

Ich versuche gdb zu Debuggen Mingw-W64 kompilierte 32-Bit-Binärdatei. Allerdings gibt gdb viele Warnungen und zeigt keine Stack-Trace. Wie kann ich diesen Prozess normalerweise debuggen?

Hier sind einige relevante Details:

• Diese GDB wurde als "x86_64-pc-Cygwin" konfiguriert.
• GNU gdb (GDB) (Cygwin 7.10.1-1) 7.10.1
• Ich kompiliere WxWidgets Bibliothek und bauen mein Programm damit. Aber das sollte für diese Frage nicht relevant sein, außer dass --host=i686-w64-mingw32 --build=i686-pc-cygwin Flags mit wxWidgets configure verwendet wurden.

Gdb ist 64 bit binary und 32 Bit. Ich kann versuchen, mit 64-Bit-Binärdatei, aber ich bin mir nicht sicher, warum Mingw-W64 G ++ Compiler keine 64-Bit-Binärdatei generiert.

Cygwin ist 64 Bit.

Ich habe kompilierte Binärdatei mit:

i686-w64-mingw32-g++ -ggdb -O0 binReach.cpp `wx-config --cxxflags 
--libs std` -Wall -o program -static-libgcc -static-libstdc++ -Wl, 
-Bstatic,-lstdc++,-lpthread -Wl,-Bdynamic 

Answer 1

von einem 32-Bit-GDB für die Fehlersuche verwenden: http://www.equation.com/servlet/equation.cmd?fa=gdb
