Question

我正在尝试编译一个处理mMIPS指令集内硬件剪辑的.c文件，但是我似乎在''results = sfu1'的行中得到错误''在宏数参数数量上存在分歧'' '当我尝试使用lcc -o mips_mem.bin image.c编译我的文件时。我不明白为什么它会给我这个错误。
这是image.c：

#!/bin/bash

if [ "$(id -u)" != "0" ]; then
  echo "Must be root to run this script!"
  exit 1
fi

##### CONSTANTS -

}

有人可以解释这个错误的含义以及修复方法吗？

sfu1宏需要2个参数，但您只提供一个参数。

这段代码会导致同样的错误：

result = sfu1(1);

校正：

result = sfu1(

               -7 * (int)buf_i[(a - 1) * WIDTH + b - 1] +
               5 * (int)buf_i[(a - 1) * WIDTH + b] +
               2 * (int)buf_i[(a - 1) * WIDTH + b + 1] +
               -1 * (int)buf_i[a      * WIDTH + b - 1] +
               15 * (int)buf_i[a      * WIDTH + b] +
               -1 * (int)buf_i[a      * WIDTH + b + 1] +
               2 * (int)buf_i[(a + 1) * WIDTH + b - 1] +
               5 * (int)buf_i[(a + 1) * WIDTH + b] +
               -7 * (int)buf_i[(a + 1) * WIDTH + b + 1] +
               128

             , 2  // <<<<<<<<< missing argument in your snippet
            );

我刚刚添加2作为第二个参数作为示例，因此您的程序编译时没有错误，但它可能不起作用。我不知道那些宏的第二个参数应该是什么。

您的代码可能不正确或调用未定义的行为，但这是另一个问题。

错误，宏观协议中存在分歧
