当构建gcc / libstdc ++时使用什么配置选项？

问题描述

阅读后在DLL和EXE之间传递空的 std :: string 对象，我担心用于构建我的gcc / libstdc ++的配置选项。更具体的我想知道在 ./ configure 期间是否使用 - enable-fully-dynamic-string / p>

我在Windows XP上使用MinGW 4.4.0。

1. 任何人都知道用于构建此版本的配置




2. 有任何安装GNU gcc的通用方法吗？

感谢您的投入！

gcc -v 打印出配置选项：

  $ gcc -v 
使用内置规格。

After reading about the problem of passing empty std::string objects between DLLs and EXEs, I am concerned about the configure options used to build my gcc / libstdc++. More specific I want to know if --enable-fully-dynamic-string was used during ./configure.

I'm using MinGW 4.4.0 on Windows XP.

1. Does anybody know the configuration used to build this release?

2. Is there a general way to find this information for any installation of GNU gcc? The gcc manual gives me no hint on this topic.

Thanks for your input!

gcc -v prints out the configuration options among other stuff:
