我們正在遷移到新的 Ubuntu 服務器（較新的 Ubuntu 版本），舊版本無法正常作業。我們從 c /9 中得到了大量的錯誤。下面舉幾個例子。知道如何讓構建（單個 .cpp 檔案）使用 g 作業嗎？

uj5u.com熱心網友回復：
我設定了一個test.cpp并包含myapp.cpp與它相同的標題并且它有效。很奇怪，所以我然后嘗試了#define其中包含的一些專案myapp.cpp并再次嘗試，成功了。現在在myapp.cpp包含檔案soap-client.h的中間代碼中得到了CGI支持。我將#includefor that 與其他#include專案一起移到頂部，它編譯得很好。
我唯一的想法是代碼中一定有一些東西，要么 a function，typedef要么#define與某些標準頭檔案沖突？
無論如何，如果你遇到類似的事情，這里有一件事要檢查。
