c++ - Issues of running C++11 executable compiled with gcc 4.7 on a computer with an older gcc / glibc / libstdc++

Question

I am a newbie to C++ compilation in production environment I wonder if there are any issues in running a C++11 executable compiled with gcc4.7 ( on debian 6 ) on a computer with an older gcc version, an older glibc / libstdc++.

Thanks

EDIT :

I want to add more details to my question ( maybe it's better to open a new question ? )

I need to compile a legacy C++ code with new libs in C++11

• on debian 7 ( for gcc 4.7 ) and run the exe on debian 6
• on fedora 18 ( for gcc 4.7 ) and run the exe on centos 6

How to achieve this ?

这确实取决于系统，但总的来说，对于 libc，应该没有任何真正的问题，除非您使用的是最近才添加的一些特殊功能。libc 的设计目标之一是始终保持兼容。

libstdc++ 是另一回事，我强烈建议静态链接它（-static-libstdc++）。
