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命令文件。这主要是由于可以传递到 CreateProcess 调用。

这在 Linux 系统上不是什么问题，但在执行 Unix 应用程序（例如 gcc）的 cygwin 端口时，同样的限制适用。

因此，有谁知道 gcc/g++ 是否也支持某种类型的命令文件？

Answer 1

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.

如果您的平台有的话，您还可以使用 xargs 来临时配置此类内容。
