How can I get rid of the __imp__ prefix in the linker in VC++?

Question

I\'m using libcurl and am getting the following sort of linker errors in VC++ 10.

1>main.obj : error LNK2019: unresolved external symbol __imp__curl_easy_         


        

Answer 1

You are using a header file that defines the function prototype with the specifier evaluating to __declspec(dllimport)

You need to either redefine the statement that is evaluating to this (set it to nothing), or use a different header file altogether.

Typically you'll see code like this:

#ifdef FOO_EXPORTS
#define DLLSPEC __declspec(dllexport)
#else
#define DLLSPEC __declspec(dllimport)
#endif

...

DLLSPEC bool foo(int bar);

Compiling the project with FOO_EXPORTS defined will use one mode and without it will use the other.
