.lib Files as Linker Input

LINK accepts COFF standard libraries and COFF import libraries, both of which usually have the extension .lib. Standard libraries contain objects and are created by the LIB tool. Import libraries contain information about exports in other programs and are created either by LINK when it builds a program that contains exports or by the LIB tool. For information on using LIB to create standard or import libraries, see LIB Reference. For details on using LINK to create an import library, see the /DLL option.

A library is specified to LINK as either a file name argument or a default library. LINK resolves external references by searching first in libraries specified on the command line, then in default libraries specified with the /DEFAULTLIB option, and then in default libraries named in .obj files. If a path is specified with the library name, LINK looks for the library in that directory. If no path is specified, LINK looks first in the directory that LINK is running from, and then in any directories specified in the LIB environment variable.

To add .lib files as linker input in the development environment

  1. Open the project's Property Pages dialog box. For details, see Setting Visual C++ Project Properties.

  2. Click the Linker folder.

  3. Click the Input property page.

  4. Modify the Additional Dependencies property.

To programmatically add .lib files as linker input

Example

The following sample shows how to build and use a .lib file:

// lib_link_input_1.cpp
// compile with: /LD
__declspec(dllexport) int Test() {
   return 213;
}

And then:

// lib_link_input_2.cpp
// compile with: /EHsc lib_link_input_1.lib
__declspec(dllimport) int Test();
#include <iostream>
int main() {
   std::cout << Test() << std::endl;
}

Output

213
