Use of libraries

[Nobody/Anonymous]

I have wrote a windows program to play a number of sounds. I have wrote the appropriate resourse file. When compiled ,the errors reported are undefined reference to PlaySound. I realise that a library must be included. But which one and how do I include it in the project. The program code is below. Any help would be appreciated

// PROG6_3.CPP - basic sound

libwinmm.a

How Do i include this library in my project though

[Nobody/Anonymous]

Hi there!
I guess -lwinmm should do the trick... Go to project options and enter "-lwinmm" as a linker option.
Hope this helped..
