我无法让 gcc 工作
我必须编译一个 matlab 工具箱附带的 .c 文件。
为此，我下载了 xcode 3.1.4，现在我正在尝试类似的命令
gcc -o solvemc solvemc.c
并收到类似的错误

I have to compile a .c file that came with a matlab toolbox.
To this end I downloaded xcode 3.1.4, and now I am trying commands like
gcc -o solvemc solvemc.c
and getting errors like

看起来您缺少一个或多个库 - 请检查 Matlab 文档以了解编译代码所需的库。
Looks like you're missing one or more libraries - check the Matlab docs as to which libraries are required in order to compile your code.
您缺少一些库。查看您的代码使用哪些库，并将链接参数添加到您的 gcc 行：
-l。您可能还需要添加路径：-L/path/to/libdir。You're missing some libraries. Look at what libraries your code uses and add link parameters to your gcc line:
-l<libname>. You may have to add paths too:-L/path/to/libdir.您可能需要链接数学库。将
-lm添加到您的 gcc 行。You probably need to link in the math library. Add a
-lmto your gcc line.
