问题描述
我们的构建系统已经改变，以至于优化的构建不再将-DNDEBUG添加到编译行。我搜索我们的makefile，没有找到这个。
Our build system has somehow changed such that optimized builds are no longer getting the -DNDEBUG added to the compile line. I searched our makefiles and don't find this.
所以问题是，-DNDEBUG在哪里为大多数人发起，怎么改变？之前我们确实有-DNDEBUG，我不认为这是从我们的任何makefile中删除。
So the question is, where does -DNDEBUG originate for most people and how might that have changed? Before we did have -DNDEBUG and I don't think this was removed from any of our makefiles.
谢谢。

推荐答案
由于编译器无法决定自己何时添加NDEBUG定义， ，该标志总是由makefile或项目文件设置（取决于你的构建系统）。
Since the compiler can't decide on its own when to add the NDEBUG define and when not to, the flag is always set by either the makefile or project file (depending on your build system).
