I have added the header file using this path: project's Properties (in C/C++ -> General -> Additional Include Directories) Also i have linked the library using http://stackoverflow.com/questions/23276399/error-lnk2019-unresolved-external-symbol-error-in-visual-studio-2010 this path: Project Properties -> Linker -> Input -> Additional Dependencies.

I would recommend you check the symbols contained in the .lib file you're trying to link to with the following command: dumpbin.exe -headers libsndfile.lib.

Background information: I recently got the Logitech G19s. It has a small color LCD screen. You can write apps for it in C++. So I decided to try it out, even though I'm new to C++, and write some hello world. Shouldn't be to dificult, but it turns out to be a real pain! Problem: When I compile my small Hello World app, I get 2 errors: LNK1120 and LNK2019, without any other information. Here's my unresolved external symbol code: #pragma comment(lib, "LogitechLcd.lib") #include "LogitechLcd.h" int main() { LogiLcdInit(L"Hello World", LOGI_LCD_TYPE_COLOR); while (true) { LogiLcdUpdate(); LogiLcdColorSetText(4, L"Hello G19s", 255, 0, 0); } LogiLcdShutdown(); return 0; } and here's the LogitechLcd.h (pastebin.com). When I compile this (with Visual Studio Professional 2013), I get the errors mentioned above. Can anyone help me out (and, if possible, explain why it doesn't work)? EDIT: I somewhat got it to work now! Viusal Studio didn't find the lib, so I had to place it in the project folder. Very stupid mistake! c++ compiler-errors visual-studio-2013 logitech share|improve this question edited Jan 3 '14 at 12:37 asked Jan 1 '14 at 16:31 ionree 10115 Those are no compiler errors, but linker errors (LNK = LINKER or LINK). Make sure the file LogitechLcd.lib can be found. –dyp Jan 1 '14 at 16:35 Don't make us guess at the errors. –Hans Passant Jan 1 '14 at 16:35 1 Please copy the exact output. These are errors from the linker. It can't find symbols. You are probably not passing the path to the library to the linker. –TimDave Jan 1 '14 at 16:36 ok, here's the exact output: –ionree Jan 1 '14 at 16:47 Fehler 2 error LNK1120: 1 nicht aufgelöste Externe E:\Freizeit\Programmieren\G19s\thisWillWork\Debug\thisWillWork.exe 1 1 thisWillWork Fehler 1 error LNK2019: Verweis auf nicht aufgelöstes externes Symbol "_WinMain@16" in Funktion "___tmainCRTStartup".
