VS2010 - Linker error with adding static library

Question

I wanted to create a static library to use in my project like Boost library for example.
So I created a Win32 console application project and I chose static library and I compiled it.
Then, in my project I added the directory containing .h file in Properties/Configuration Properties/VC++ Directorie/Include Directories and the directory containing .lib file in Properties/Configuration Properties/VC++ Directorie/Libraries Directories like Boost library, but I have error "LNK2019 unresolved external symbol".

Why it simply doesn't work like boost library while I make the same process?

Why with boost, I don't need to add it to the linker inputs? — moth

How to create or add a static library without add it to the linker inputs. Because I frequently use library which I include it as describe in my first post (my question). Else when I add it to the linker inputs, it doesn't work : error LNK2005. — moth

may be you forgot to write:

#pragma comment(lib, "boost.lib")

in your code

No, boost works very good. This is my own library I created which doesn't work.

just replace "boost.lib" with your own library name

maybe because of different CRT libraries. try to set /MDd for both application and library msdn.microsoft.com/en-us/library/2kzt1wy3.aspx

I was wrong. Actually, #pragma comment(lib, "myLib.lib") works perfectly. I had #pragma comment(lib, "myLib.lib") in my header file and it works with adding the directory containing .h file in Properties/Configuration Properties/VC++ Directorie/Include Directories and the directory containing .lib file in Properties/Configuration Properties/VC++ Directorie/Libraries Directories. Sorry and thx.

You need to specify the name of the library to use (in additional dependencies in the linker options) as well as tell it which directory the additional libraries are in.

You can use #pragma comment instead, but it can be more manageable to use the build settings.

Boost is partly header only, so you don't have to link any library to use it. And I am not sure if boost also suuport pragma comment linkage.

First, boost is partly header only - apart from the libraries. Second, anything can use the pragma comment lib, but since was given in another answer I wanted to point out there are other ways of doing this - you can get in a mess if you need different debug and release versions.
