static libraries

[john tindell]

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.

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

do u know where it is in VC++ 7, because i cant find it?

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

okay, i can only get to the linker part when the project congiuration is set as .DLL and im trying to make a .LIB???

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.
