Dev C++ Undefined Reference To __imp_wsastartup'
May 25, 2018 I am getting the following compiler message when attempting to use AlphaBlend: undefined reference to `impAlphaBlend' The MSDN lists the requirements for AlphaBlend: Requirements: Minimum supported client Windows 2000 Professional desktop apps only Minimum supported server Windows 2000 Server desktop apps only Header WinGdi.h (include Windows.h). Mar 06, 2016 There's a FAQ here that tells you how to implement your own 'gotoxy' in Windows: gotoxy and textcolor - error: undefined reference And other that gives you alternatives to color your text in Windows (see the second bit of code): FAQ Color my text - Cprogramming.com. By including the header in your main file, the compiler is informed of the description of class Hash when compiling the file, but not how class Hash actually works. When the linker tries to create the entire program, it then complains that the implementation (toHash::insert(int, char)) cannot be found. Here, we are going to learn why an Error: Id returned 1 exit status (undefined reference to 'main') occurs and how to fixed in C programming language? A humble request Our website is made possible by displaying online advertisements to our visitors. Apr 22, 2014 Put simply, the “undefined reference” error means you have a reference (nothing to do with the C reference type) to a name (function, variable, constant etc.) in your program that the.
