在用mingw-w64编译的cygwin窗口中调试32位二进制文件

我想用gdb调试mingw-w64编译的32位二进制文件。但是，gdb给出了很多警告，并没有显示任何堆栈跟踪。我怎样才能正常调试这个过程？在用mingw-w64编译的cygwin窗口中调试32位二进制文件

这里有一些相关的细节：

这GDB被配置为 “x86_64的-PC-cygwin的”。
GNU gdb（GDB）（Cygwin 7.10.1-1）7.10.1
我在编译wxWidgets库并用它构建我的程序。但这不应该与这个问题有关，除了--host=i686-w64-mingw32 --build=i686-pc-cygwin标志与wxWidgets configure一起使用。

GDB是64位和二进制是32位。我可以用64位二进制尝试，但我不知道为什么mingw-w64 g ++编译器不生成64位二进制。

cygwin是64位。

我已经编译好的二进制有：

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

我想我打这个问题：https://virtuallyfun.superglobalmegacorp.com/2015/ 10/04/32bit-64bit-gdb-collision/ 但我在cygwin64中找不到任何gdb32.exe –

要生成32位目标，你应该在wxWidgets build和你的程序中使用'-m32'标志。 – Ripi2

@ Ripi2二进制文件已经是32位。我需要它是64位。 –
