(C++) ::swprintf has not been declared

 

 

::swprintf has not been declared is a compile error I encountered when using Qt Creator under Windows 7.

 

 

 

 

 

Solution

 

Add the following statement before the first #include:

---

#undef __STRICT_ANSI__

 

Or more portable:

 

---

#ifdef _WIN32 #undef __STRICT_ANSI__ #endif
