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

What to do when you've put your co-worker on spot by being impatient? I've been having a LOT of trouble with other third party libs, so I wonder if that's the issue there too. The decorated name is the name the linker searches for to resolve external symbols. I have tried installing and re-installing Windows 7 SDK and Visual Studio - I am also on Windows 7.
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 .....
The most important item is that the linker is looking for the symbol [email protected] The name has some gunk on it, but fortunately it's pretty recognizable anyway. Fatal Error Lnk1120 You can ignore all the cmake stuff. ExamplesHere are several examples of code that causes a LNK2019 error, together with information about how to fix the error. Declarations must include the same template parameters as the definition.
How do I fix this error? Answer:The error is thrown when the linker cannot find the CyAPI.lib library file. https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/277002 Related Content 1 Answer Friedrich (view profile) 1 question 630 answers 389 accepted answers Reputation: 1,837 Vote0 Link Direct link to this answer: https://www.mathworks.com/matlabcentral/answers/11781#answer_16103 Answer by Friedrich Friedrich (view profile) 1 Error Lnk2019: Unresolved External Symbol Not the answer you're looking for?
