Question : Problems when using static lib - MS VC++

Hi,

I created a static library from a c program and am trying to use it in another c program in MS VC++.

Now I'm getting a whole bunch of link warnings and errors...

Thanks for your help.

Answer : Problems when using static lib - MS VC++

First, check in the project properties -> Linker -> input  that Ignore all default libraries is not set to Yes.

Second, It is to do the way you are linking with MFCs.
In the projet properties -> Configuration properties -> General -> Use of MFC  set Use MFCs in a static library.

Good luck.
