我想知道是否有办法编写带有.s扩展名的MIPS汇编语言文件（只是非常简单的测试文件），就像PCSpim模拟器一样，然后让它实际编译代码并生成一个文件十六进制输出就好像我将它加载到一个实际的MIPS芯片上一样。
SPIM或其他类似软件可以这样做吗？你能解释一下从MIPS组件到微控制器使用的实际可执行程序的组装过程吗？
由于
编辑：所以我在安装了gcc的ubuntu linux上运行。我有一个mips文件mipsTest.s，它是以下
.text
add $7, $0, $0
现在在命令行输入
gcc -c -o mipsy.o mipsTest.s
我得到的错误是
mipsTest.s: Assembler messages:
mipsTest.s:2: Error: at most 2 immediate operands are allowed.
所以对我来说这意味着汇编程序没有读取mips语言，可能假设我的汇编文件是在x86中？如何获得交叉编译器设置以便gcc识别MIPS汇编语言而不是x86？ （或者现在正在解释我的mipsTest.s文件）谢谢！
编辑2：所以我用Google搜索“mips cross-assembler”并找到了一些东西。看起来最有希望的是sourceforge上的umps交叉汇编程序项目。所以我下载了umps2.0，这应该是一个稳定的版本。我按照自述文件中的说明运行了“./configure”。然后我的控制台给了我以下错误，这阻止我运行make命令...

Consider adjusting the PKG_CONFIG_PATH environment variable if you

Alternatively, you may set the environment variables SIGCPP_CFLAGS
and SIGCPP_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
所以我运行了一个快速的sudo apt-get install sigc ++ - 2.0但找不到包...建议？
编辑4：以下是我尝试使用Makefile时出现的错误

答案 0 :(得分：3)
您可以使用gcc来交叉编译或汇编MIPS汇编语言源。就过程而言，汇编语言助记符和机器指令之间存在一对一的映射。汇编程序只为您进行翻译。
编辑：你没有使用交叉汇编程序，你正在使用系统自己的gcc。该工具链可能针对的是英特尔处理器，它没有3操作数add指令。您需要为MIPS使用交叉汇编程序。下载并安装二进制文件，或自己构建工具链。然后你将有一个交叉编译器（可能称为mips-gcc或类似的东西），你可以使用它来组装你的MIPS源文件。
