失去了一些東西我安裝了CodeSourcery的G ++工具鏈，並試圖編譯一個簡單的Hello World程序：在手臂G ++
#include <iostream>
using namespace std;
int main()
{
cout << "Hello World" << endl;
return 0;
}
，並得到了很多錯誤從鏈接

什麼庫時我錯過了嗎？
看起來它缺少運行時。也許像'crt0.o'或'-lc'？ –
@Kerrek SB，'-lc'沒有幫助，我在libgcc目錄中沒有'crt0.o'，只有'crtbegin.o'，'crtend.o'，'crti.o'，'crtn。以'crt'開頭的'o'。 – Dani
嘗試使用'-v'標誌運行編譯器並查看輸出。你應該看到'collect2'的實際參數，它應該包含像'-lc'和'.../crt1.o'這樣的東西。如果他們不這樣做，你的編譯器配置錯誤，請嘗試重新安裝它。 –
