Visual Studio 2012女士，“未解决的外部符号”

Question

I am trying to compile a C++ application through Microsoft Visual Studio 2012. I have linked the Boost, Jni, Acml libraries to the application.

When I click on rebuild, the compilation does not finish. This is the first error I get:

Error 28 error LNK2019: unresolved external symbol _sgesdd referenced in function "void __cdecl testLapackDGESDD_EASY(void)" (?testLapackDGESDD_EASY@@YAXXZ) C:\\Users\\DavideChicco\\Documents\\Visual Studio 2012\\Projects\\Solution\\mainConsole.obj

Do you have any idea of what this is related to?

Thanks

Answer 1

Your compilation seems to have finished, but the error happens during linking: the definition of the function _sgesdd called in testLapackDGESDD_EASY is not found. So
- either this function is defined in an external dll , and you need to add the lib in your solution,
- or this function is supposed to be defined in your project, and you need to implement its definition.

Answer 2

啊哈，编译器找不到函数“ _sgesdd”，我建议您添加由DLL作者提供的库。
