Error LNK2019

[TimNick90]

I am having a problem with my program for a class of mine and my instructor has tried to help me out. But he does not know what the error is and has looked up some things. From what I have researched I understand the error LNK2019 is saying that there is a function or something either misspelled or I am using different versions of a library in different parts of my program. The thing I do not under stand about that is that there is only the main page in this program it refers to several graphics library's, thats it. I was having the same problem with a similar program and solved it by adding another graphics library only this time that hasn't worked. If anyone is familiar with this error and could help me that would be greatly appreciated. Thanks

An LNK2019 always means an unresolved external reference. That is, you have referred to something (it's mame is in the LNK2019 message) but have failed to provide a defintion.

Look at what's missing. Is it one of your things or somethng from a library you are using? In either case you have to define that thing by writibng the definition yourself or adding the necessary library to your build.

As W4cats suggested, take a look at what is missing in the error message. If its something created or called by your code, then fix it.

The other possibility is that the missing routine is needed by the graphics library and not called directly by your code. This means your library is missing some code, probably another library. Its pretty common for a 3rd party library to need other libraries installed. Its not that much fun figuring out what is needed.

In this case go to libraries home page and see what dependencies it needs. If worst comes to worst, reinstall the library and its dependencies. Be carefull of the versions of the needed libraries. An old version might be missing what you need.

One last trick is to google the complete error message (minus any reference to your source code names). Someone else has probably run into this error.

I figured it out, there was a function was a misspelling of one function that had the same name as another function so I didn't catch it before, deltay() and delay(). Thanks
