無法在Ubuntu中編譯簡單的C++程序

Question

我試圖在終端中構建一個簡單的程序。

#include <stdio.h> 
#include <stdlib.h> 
int main() 
{ 
     printf("TESTING"); 
     return 1; 
} 

我跑的g ++ -o測試TEST.CPP

的錯誤：

/usr/include/features.h:323:26: error: bits/predefs.h: No such file or directory 
/usr/include/features.h:356:25: error: sys/cdefs.h: No such file or directory

/usr/include/stdlib.h:160: error: ‘__END_NAMESPACE_C99’ does not name a type 
/usr/include/stdlib.h:168: error: ‘__END_NAMESPACE_STD’ does not name a type 

名單還在繼續這種方式。我希望有人能指出我沒有做的工作。

Answer 1

解決方法：由於之前嘗試使其工作，我的路徑爲空。我創建了一個乾淨的路徑使用：

export PATH= /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin 

我編譯後的問題是，該程序不會顯示任何結果。這是因爲作爲一個新的Linux用戶，我沒有意識到我需要用./在前面調用一個程序。這可以設置路徑以及通過呼籲：

export PATH: $PATH:./

您的代碼適用於我的平臺。

錯誤消息看起來像C錯誤。也許使用C++頭文件會有所幫助。

#include <cstdio> 
#include <cstdlib> 

int main(int argc, char *argv[]) { 
    printf("TESTING"); 
    return 0; 
} 

你也可能有一些奇怪的別名。有時候人們會錯誤地將gcc設置爲g ++的別名。

tom@flim:~$ set | grep g++ 

tom@flim:~$ alias grep 
alias grep='grep --color=auto' 

tom@flim:~$ alias g++ 
bash: alias: g++: not found 

tom@flim:~$ which g++ 
/usr/bin/g++ 

tom@flim:~$ ll `which g++` 
lrwxrwxrwx 1 root root 7 2011-08-14 02:17 /usr/bin/g++ -> g++-4.6* 

tom@flim:~$ g++ --version 
g++ (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1

這是怎麼設置我的開發環境在Ubuntu：

sudo apt-get install build-essential 

這將設置所有的標準C++庫，而無需知道knitty堅韌不拔的細節。

我有一個非常類似的問題，這一點。在我的情況的問題是，我有證明，試圖查看他們一些損壞的頭文件：

/usr/include/x86_64-linux-gnu/sys$ cat * | grep "Input/outpu error" 
cat: ioctl.h: Input/output error 
cat: types.h: Input/output error 

對我來說，解決辦法就是清除這些文件，然後重新安裝它們。

sudo apt-get purge libc6-dev 
sudo apt-get install libc6-dev
