static libraries

im trying to make a *simple* static library with only one function inside it. all it does it multiply two numbers together and thats it. now when i compile the .lib file there are no errrors and theres nothing wrong. When i include the header file with another project (header file has been copyed to the same directory) it gives me these error.

Quote:

uselibtest error LNK2019: unresolved external symbol "double __stdcall multnum(double,double)" (?multnum@@YGNNN@Z) referenced in function _main

uselibtest fatal error LNK1120: 1 unresolved externals

any ideas whats wrong?

Cheers :)

Did you move the .lib file to somewhere in the compiler's library path? Also you need to tell it to link against that library.

For VC++, go to Project Settings, then the Linker tab. Add the filename of the .lib file to the list :)

Right-click the project in the solution explorere, select properties.
Go to Linker->Input and add the name to the additional dependencies.

No, you've *made* the .lib already. You need to add it to the linker settings for the DLL or program you're creating. A .lib file doesn't go through the linker, therefore no Linker settings.
