C++ Visual Studio 11 GLFW 外部符号错误

Visual Studio 11 GLFW external symbol error

提问by Michael

The basic code I use is the example from http://www.glfw.org/documentation.html

我使用的基本代码是来自http://www.glfw.org/documentation.html的示例

I get this output:

我得到这个输出：

The glfw3.h is in the VC/include directory. I've also added the glfw3.lib to the VC/lib folder and I added the glfw3.lib as an additional dependency to the linker input but I still get this errors.

glfw3.h 位于 VC/include 目录中。我还将 glfw3.lib 添加到 VC/lib 文件夹中，并将 glfw3.lib 添加为链接器输入的附加依赖项，但我仍然收到此错误。

Any Idea why? I've used the precompiled binaries (which support MSVC2012 and 64x) http://www.glfw.org/download.html

任何想法为什么？我使用了预编译的二进制文件（支持 MSVC2012 和 64x）http://www.glfw.org/download.html

Ok, after very much trial and error I solved it.

好的，经过反复试验，我解决了它。

1. Use the 32-bit binaries
2. Right click on the project -> Properties -> VC++
3. Include Directories: C:\Users\MICHAEL\Desktop\glfw-3.0.3.bin.WIN32\include;$(IncludePath)
4. Library Directories: C:\Users\MICHAEL\Desktop\glfw-3.0.3.bin.WIN32\lib-msvc110;$(LibraryPath)
5. Linker -> Input -> Additional Dependencies add
6. glfw3.lib and opengl32.lib

1. 使用 32 位二进制文​​件
2. 右键单击项目-> 属性-> VC++
3. 包含目录：C:\Users\MICHAEL\Desktop\glfw-3.0.3.bin.WIN32\include;$(IncludePath)
4. 库目录：C:\Users\MICHAEL\Desktop\glfw-3.0.3.bin.WIN32\lib-msvc110;$(LibraryPath)
5. 链接器 -> 输入 -> 附加依赖项添加
6. glfw3.lib 和 opengl32.lib

That solved it for me.

那为我解决了。

This is my solution if someone is intended to use 64 bit version of GLFW:

如果有人打算使用 64 位版本的 GLFW，这是我的解决方案：

1. Get GFLW source code from github.
2. Using CMake to generate 64 bit Visual Studio sln.
3. Configure the glfw using proper settings:

1. 从 github 获取 GFLW 源代码。
2. 使用 CMake 生成 64 位 Visual Studio sln。
3. 使用适当的设置配置 glfw：

In case of dynamic library:

Project -> Configuration -> C/C++ -> Code Generation -> Runtime Library -> Multi-threaded Debug DLL (/MDd)

In case of static library:

Project -> Configuration -> C/C++ -> Code Generation -> Runtime Library -> Multi-threaded Debug (/MTd)

如果是动态库：

项目 -> 配置 -> C/C++ -> 代码生成 -> 运行库 -> 多线程调试 DLL (/MDd)

如果是静态库：

项目 -> 配置 -> C/C++ -> 代码生成 -> 运行库 -> 多线程调试 (/MTd)

1. Build the glfw project.

2. Link the following binary in your project:

   glfw3.lib;opengl32.lib;kernel32.lib;user32.lib;gdi32.lib;winspool.lib;shell32.lib;ole32.lib;oleaut32.lib;uuid.lib;comdlg32.lib;advapi32.lib;glfw3.lib
   

3. Also configure your project using corresponding /MDd or /MTd compiler flag and configure it to build on x64.

4. Build.

4. 构建 glfw 项目。

5. 在您的项目中链接以下二进制文件：

   glfw3.lib;opengl32.lib;kernel32.lib;user32.lib;gdi32.lib;winspool.lib;shell32.lib;ole32.lib;oleaut32.lib;uuid.lib;comdlg32.lib;advapi32.lib;glfw3.lib
   

6. 还可以使用相应的 /MDd 或 /MTd 编译器标志配置您的项目，并将其配置为在 x64 上构建。

7. 建造。

Make sure that your platform is set to x64 or 32 based on what version you're using. I tried getting the 64 bit platform and I kept running into issues until I noticed that my active platform in Visual Studio was win32. Go to the configuration manager and make sure its set to 64

确保根据您使用的版本将您的平台设置为 x64 或 32。我尝试使用 64 位平台，但一直遇到问题，直到我注意到 Visual Studio 中的活动平台是 win32。转到配置管理器并确保将其设置为 64

I do not have the needed reputation to comment on the accepted answer (by Michael), but I'd like to note that I got his method working. What I needed to correct was switching the include and library directories BEFORE the rest of the IncludePath/LibraryPath instead of AFTER it.

我没有必要的声誉来评论接受的答案（迈克尔），但我想指出我让他的方法起作用了。我需要更正的是在 IncludePath/LibraryPath 的其余部分之前而不是在它之后切换包含和库目录。
