C++ compile error (LNK1120 and LNK2019) with Visual Studio
提问by ionree
I am a newbie to C++ and I need help with a very basic program.
我是 C++ 的新手，我需要一个非常基本的程序的帮助。
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!
背景信息：我最近拿到了罗技G19s。它有一个小的彩色液晶屏。您可以使用 C++ 为其编写应用程序。所以我决定尝试一下，即使我是 C++ 的新手，并写了一些 hello world。不应该太难，但事实证明这是一个真正的痛苦！
Problem:When I compile my small Hello World app, I get 2 errors: LNK1120 and LNK2019, without any other information. Here's my code:
问题：当我编译我的小型 Hello World 应用程序时，我收到 2 个错误：LNK1120 和 LNK2019，没有任何其他信息。这是我的代码：
#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).
这是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)?
当我编译这个（使用 Visual Studio Professional 2013）时，我得到了上面提到的错误。任何人都可以帮助我（并且，如果可能，请解释为什么它不起作用）？
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!
编辑：我现在有点让它工作了！Viusal Studio 没有找到这个库，所以我不得不把它放在项目文件夹中。非常愚蠢的错误！

Is it a console project? (If you don't know, look at Project Properties> Linker> System> Subsystem). It should be the first thing that comes up. If so, make your main function a wmainfunction. If it's a Win32 project it was something like WinMain(16), not sure.
它是一个控制台项目吗？（如果您不知道，请查看Project Properties> Linker> System> Subsystem）。它应该是出现的第一件事。如果是这样，请将您的主函数设为wmain函数。如果它是一个 Win32 项目，它类似于WinMain(16)，不确定。
I hope it helped.
我希望它有所帮助。
