I'm working on Visual Studio (for C++ and OpenGL but i'm a neewbie) and I've imported the code with the option in Visual Studio "Import Project From Code" but it do not compile...

The problem is that the code isn't mine (co-worker) and I cannot contact the author (vacation...) to know on witch environment he runs.. or to ask him to convert the code... I also Use FreeImage Library but i thinks it's just a detail.

I get error " Cannot start programm, the specified file cannot be found"...

Then I've got some errors for unsolvable symbols but the wierd part is that in the console it writes : 

error LNK2005: _main already defined in dummy.obj
error LNK2019: unsolved external symbol __imp_FreeImage_Initialise@4 referenced in main function
error LNK2019: unsolved external symbol __impFreeImage_DeInitialise@0
...

And so one but in the code there is no @0, what do they mean...?

  • `@0` as a suffix means that this function has a Pascal-style calling convention, a.k.a. STDCALL in the Windows API, where it is the responsibility of the called function to remove its arguments from the stack. The 0 is the length in bytes of arguments, i.e. none in this case. This is fairly common for DLL-exported functions on Windows, and chances are one of the defines in your header file that declare these functions specified the calling convention. – Rup Nov 11 '14 at 22:34

Unresolved external usually means that there is a linker dependency not met.

Basically, this message means that VS cannot find FreeImage library. In the install directory of FreeImage, there should be a .lib somewhere. In your project settings, under linker, make sure that the FreeImage .lib file is there and that the additionnal library directory contains the path where the .lib is.

  • Sorry if I've made a duplicate but I didn't find my problem... (Lack of vocabulary for Keywords...:/, english is foergin laguage for me..) I've modified that, and now VS is saying that it lacks the .dll of FreeImage.. But It's on the file with the .exe .. – Dr.L Nov 12 '14 at 07:14
