GCC有一个内置的编译时断言吗？ [英] Does GCC have a built-in compile time assert?

问题描述

我们现有的编译时断言实现是基于负数组索引，并且它在GCC上提供差的诊断输出。 C ++ 0x的 static_assert 是一个非常好的功能，它提供的诊断输出更好。我知道GCC已经实现了一些C ++ 0x功能。有没有人知道 static_assert 是否在其中，如果是那么自从什么GCC版本？

Our existing compile-time assert implementation is based on negative array index, and it provides poor diagnostic output on GCC. C++0x's static_assert is a very nice feature, and the diagnostic output it provides is much better. I know GCC has already implemented some C++0x features. Does anyone know if static_assert is among them and if it is then since what GCC version?

推荐答案

根据此网页，gcc已拥有 static_assert 自4.3。

According to this page, gcc has had static_assert since 4.3.
