The solution turned out to be that the DLL was 64 bit, and the simple app using it was 32.

To fix this, link the CyAPI.lib library to your project. A symbol is defined as static and then later referenced outside the file. You signed in with another tab or window. Error Lnk1120 1 Unresolved Externals Or most easily done by writing the linker instruction in your source code: #include "foo.h" #pragma comment(lib, "foo.lib") Which works for MSVC, not otherwise portable but linking never is.

Change this to Multi-threaded Debug (/MTd), and recompile everything. Instead of generating an inline instruction, the compiler generates a call to an external symbol with the same name as the intrinsic. The LNK2019 error is that you do not have a main program in your Fortran code. http://stackoverflow.com/questions/29556290/random-unresolved-external-symbols-that-shouldnt-be-there I have qt + msvc10 express + win sdk.7 Ok , I use the existing examples offered, (using the libs) I can't compile .....
