因此,您可能会从前几天识别出我在IDE中运行此代码时出现的类似问题。最终,我得到的建议是,我应该学会从命令行一起运行它们。因此,我接受了建议,并从Codesourcery Lite MentorGraphics安装了GNU工具链(不知道这是否合理)。我可以做的命令是类似的东西使用GNU ToolChain在Windows命令行上运行ARM/C

> arm-none-eabi-gcc -o main main.c -T script 

但是,我很难找到我应该如何使用命令。我试过

> arm-none-eabi-gcc -o main (my c filename).c -T (my ARM filename).s 

但是我从ARM文件中得到一个语法错误。然后我试图做

> arm-none-eabi-gcc -o main (my c filename).c 

但是,这并不因为外部“ADD2”

> arm-none-eabi-as add2.s 

这让我一个文件“的a.out”但我不知道是什么的工作确实。

这里是我的代码:

ARM

.global add2 
add2: 
    stmfd sp!, {v1-v6, lr} @ 'standard' entry, save registers on the stack 
    add a1, a1, a2   @ do the addition requested 
    ldmfd sp!, {v1-v6, pc} 

Ç

#include <stdio.h> /* standard input and output */ 
#include <stdlib.h> /* standard library */ 
extern int add2(int i, int j); /* tell the compiler that the routine is not defined here */ 
int main(int argc, char * argv[]) /* entry point to the program */ 
{ 
    int i, j; /* declare the variable types */ 
    int answer; 
    i = 5; /* give the variables values */ 
    j = 20; 
    answer = add2(i, j); /* call the assembly language routine */ 
    printf("result is : %d\n", answer); /* print out the answer */ 
    exit(0); /* leave the driver program */ 
} 

任何帮助,将不胜感激。我也在Windows上的Ubuntu上安装了apt-get from Bash,所以如果你有一个BASH解决方案也是可能的(https://packages.ubuntu.com/trusty/devel/gcc-arm-none-eabi

如果有人遇到过这种情况,我最终得到它的方式将这些脚本行输入到Windows命令行中:

Step 1: Compile your c-file 
arm-none-eabi-gcc -o (object file name 1) -c (c file name) 

Step 2: Assemble your ARM file 
arm-none-eabi-gcc -o (object file name 2) -c (ARM file name) 

Step 3: Link files and create executable 
arm-none-eabi-gcc -o (executable file name) (object file name 1) (object 
file name 2) -T armulator-ram-hosted.ld 

Step 4: Run the files 
arm-none-eabi-run (executable file name)
