背景：  在windows上使用Eclipse上除錯C++程式。

程式出錯如下：

問題分析：:x86-64 is not compatible with target architecture i386. 可以看出是相容性問題。我發現我的程式是使用32位編譯，卻使用了64位gdb來除錯，因此會出現此類相容性問題，其他類似的問題可以參考。

解決方案：編譯除錯要相容(compatible).以下可任選一種。

1、使用64位編譯器編譯並且使用64位偵錯程式除錯。

2、使用32位編譯器編譯並且使用32位偵錯程式除錯。

我選擇了第二種方案，即在我原來的基礎之上，修改為32位的gdb偵錯程式即可。

具體操作：在eclipse中，Debug Configurations(右擊可執行檔案，Debug as,, 即可找到)， 在Debugger對應tag下。配置制定的gdb.

總結：在IDE中，編譯器和偵錯程式使用型別不確定時，可以先在命令列模式（Command）嘗試。然後再回到IDE中手動新增。
