 In earlier versions of Visual Studio, by default or if **`/Zc:externConstexpr-`** is specified, Visual Studio applies internal linkage to **`constexpr`** variables even if the **`extern`** keyword is used. The **`/Zc:externConstexpr`** option is available starting in Visual Studio 2017 Update 15.6. and is off by default.
 
-As of Visual Studio 2022 Update 17.6, the `/permissive-` option enables both `/Zc:lambda` and `/Zc:externConstexpr`. In prior versions, neither were enabled by `/permissive-`.

-If a header file contains a variable declared `extern constexpr`, it must be marked [`__declspec(selectany)`](../../cpp/selectany.md) in order to merge the duplicate declarations into a single instance in the linked binary. Otherwise you may see linker errors, for example, LNK2005, for violations of the one-definition rule.
