Can't include a static lib(.lib) in visual c++

Question

I've added a .lib to my c project,

but still can't use things defined in that .lib in .c

main()
{
  structure_defined_inthat_lib c;
  ...

I added that .lib this way:

Right click ,property,Linker,Input,

and in "Additional Dependencies",I type in "D:\path\name.lib"

Anything wrong?

Answer 1

You need to include the header files defining the stuff in that library into the code where you want to use that stuff. That header file must be on one of the paths specified in C++->General->Additional include directories - you might need to add the path to the header to that list.

Also you only specify the filename of the library in "Additional dependencies" in the linker settings and provide the path to that file in "Additional library directories".

Answer 2

You need both the library and the header to use the functions defined in the library. If you know the function signatures, you can also declare them using extern.
