GCC是否支持命令文件

Question

MSVC编译器支持用于传递命令行选项的command files。这主要是由于可以传递给CreateProcess调用的命令行参数大小的限制。

这在Linux系统上不是问题，但在执行Unix应用程序的cygwin端口时，例如gcc，同样的限制也适用。

因此，有没有人知道gcc / g ++是否也支持某种类型的命令文件？

感谢。

当然！

@file
           Read command-line options from file.  The options read are inserted
           in place of the original @file option.  If file does not exist, or
           cannot be read, then the option will be treated literally, and not
           removed.

           Options in file are separated by whitespace.  A whitespace
           character may be included in an option by surrounding the entire
           option in either single or double quotes.  Any character (including
           a backslash) may be included by prefixing the character to be
           included with a backslash.  The file may itself contain additional
           @file options; any such options will be processed recursively.
