我想將我的C程序轉換爲MIPS指令

我想知道是否有可能在ubuntu 11.04中使用gcc將此代碼轉換爲MIPS。我試過lcc但無法安裝。我想將我的C程序轉換爲MIPS指令

#include<stdio.h> 
int fibnacci(int c) 
{ 
if(c==0) 
return 0; 
else if(c==1) 
return 1; 
else 
return (fibnacci(c-1)+fibnacci(c-2)); 
} 
int main(){ 
int i; 
printf("Enter the fib number"); 
scanf("%d",&i); 
int a; 
a= fibnacci(i); 
printf("The value is %d",a); 
}

發生了什麼？你的編譯命令是什麼？你能給你看到的錯誤嗎？ – Floris

使得LCC給出了這個錯誤： root @ ubuntu：/ home/lincon/Desktop/lcc＃make all cc -g -c -o /host.o cc：致命錯誤：沒有輸入文件編譯終止。 make：*** [/host.o]錯誤4 – Lincon

可以用gcc編譯得到MIPS代碼嗎？ – Lincon

爲了能夠生成MIPS代碼，GCC必須被配置爲交叉編譯與mips作爲靶結構。所以正確的答案 - 不，你不能在Ubuntu中使用常規的gcc。你必須得到mips交叉編譯器。要獲得它，請從軟件包管理器安裝embedian軟件包，並使用gcc-4.4-mips-linux-gnu或從源安裝mips交叉編譯器。

或者，MIPS在這裏指出幾個交叉編譯器：http://developer.mips.com/tools/compilers/。 –

該代碼不能編譯。用一個MIPS模擬器在我的Ubuntu上編譯成MIPS。

#include<stdio.h> 
int fibnacci(int c) 
{ 
if(c==0) 
return 0; 
else if(c==1) 
return 1; 
else 
return (fibnacci(c-1)+fibnacci(c-2)); 
} 
int main(){ 
int i; 
int a; 
printf("Enter the fib number"); 
scanf("%d",&i); 
a= fibnacci(i); 
printf("The value is %d",a); 
}
