creating a static library using third party libs

Hi

I have a Visual studio .sln file that has a couple of projects in it , let's call it project A,B,C. One particular project is designed such that its configuration type is a static lib. (That means it creates a static lib called MyProject.lib) . This MyProject.lib is then used by another project, one of which is the application.

I am running into a problem where I want to use some third party static lib (that sources a dynamic lib) in the project,MyProject . But since its type was a static lib, I did not have a Linker option. As a result i created another project , let's call it D, of type application, where I put files that required the third party . D builds without errors. I included the header file location in the main project A that was of type application. However, now when compiling A, I get linker errors , saying external symbol reference not found (these are the third party references) in D  functions.

anyone can show me a good way to add third party libs to a project that produces a static lib?

If you are building a library, the project has to be a library.
So you have mysatatic.lib you then have a 3rdpaty.lib but it includes references to dynamic pubs.
Your setup/project has to include the dynamic libs in the package

Do you have the source of the 3rd party lib or you only have an API reference?

you must resolve the issues in the project where you get these errors.

you have to add the static library of the third-party in the Linker - Input - Additional Dependencies what would resolve the undefined symbols when linking.

if the third-party has two static libraries, one for debug and one for release you would use the right one for your debug and release configuration. the path to the library must be added to vc directories - library directories.

note, static libraries a third-party delivered additionally to a dll, are only wrapper functions which call into the dll. it is not the same as you were doing, when you put shared function code into a static library. however, from linker's point of view it is the same: a bunch of modules which can be added once to an executable at link time (and which itself may demand for other external references).
