-1
當我編譯我的程序時沒有使用g++ -o
選項,它會失敗並出現以下錯誤: 它沒有抱怨的符號在我的程序中。爲什麼它會與-o
選項編譯得很好,但如果沒有這個選項就無法編譯?g ++中沒有-o選項的分段錯誤

有沒有解釋?我在這裏錯過了什麼嗎?
使用G ++(Ubuntu的4.4.3-4ubuntu5.1)4.4.3
感謝
'-o'作爲輸出?發佈你的命令行。 – Pubby 2012-03-17 10:45:22
你顯然沒有說出全部的真相,除了'-o'之外,你還指定了哪些其他的東西? – 2012-03-17 10:49:10
g ++ -o integer integer.cc(編譯好)但是當我做g ++ -g integer integer.cc(或g ++ integer integer.cc)時失敗 – maress 2012-03-17 10:55:46
