在Eclipse上调试C++程序报错：x86-64 is not compatible with target architecture i386.

背景：  在windows上使用Eclipse上调试C++程序。

程序出错如下：

问题分析：:x86-64 is not compatible with target architecture i386. 可以看出是兼容性问题。我发现我的程序是使用32位编译，却使用了64位gdb来调试，因此会出现此类兼容性问题，其他类似的问题可以参考。

 

解决方案：编译调试要兼容(compatible).以下可任选一种。

1、使用64位编译器编译并且使用64位调试器调试。

2、使用32位编译器编译并且使用32位调试器调试。

我选择了第二种方案，即在我原来的基础之上，修改为32位的gdb调试器即可。

具体操作：在eclipse中，Debug Configurations(右击可执行文件，Debug as,, 即可找到)， 在Debugger对应tag下。配置制定的gdb.

总结：在IDE中，编译器和调试器使用类型不确定时，可以先在命令行模式（Command）尝试。然后再回到IDE中手动添加。
