代码::阻止对"*"的未定义引用 [英] Code::Blocks undefined reference to "*"
问题描述
就像标题中所说的那样，我在使用C :: B时遇到多个构建错误，所有人都在说undefined reference to '*'.我正在尝试使用OpenGL，GLFW和GLEW构建程序.每次找不到的前三件事是_imp__CreateDCW@16，_imp__GetDeviceCaps@8，_imp__DeleteDC@4.在Internet上浏览时，我看到所有这些方法都在gdi32库中，并确保将其添加到链接器中.一旦尝试使用GLFW3中的方法，该错误似乎就发生了.我尝试使用MinGW使用不同版本的GLFW，这就是我在Code :: Blocks中使用的版本，但是我无法摆脱错误.
Like the title says, I'm getting multiple build errors using C::B, all are saying undefined reference to '*'. I'm trying to build a program using OpenGL, GLFW, and GLEW. The top three things that it cant find every time are _imp__CreateDCW@16, _imp__GetDeviceCaps@8, _imp__DeleteDC@4. When looking on the internet, I saw that all of those methods were in the gdi32 library, which I made sure to add to the linker. The error appears to be happening as soon as I try to use methods from GLFW3. I've tried using different builds of GLFW using MinGW, which is what I'm using with Code::Blocks, but I cannot get the error to go away.
我正在使用Code :: Blocks 13.12在Windows 8.1上进行开发.
I am developing on Windows 8.1, using Code::Blocks 13.12.
以下是我链接的所有内容的列表，并且顺序相同:
Here is a list of everything I am linking and in the same order:
- gdi32
- 内核32
- user32
- opengl32
- glu32
- glfw3
代码::: Blocks看起来有点麻烦，但我真的很想开始习惯它.感谢任何可以提供帮助的人.
Code::Blocks is turning out to be a bit of a hassle, but I really want to start to get used to it. Thanks to anyone who can help.
推荐答案
您必须通过-lgdi32以便链接程序知道您正在使用GDI函数.顺序也很重要.在带有MinGW 4.8.1工具链的Windows 8上，我给出了这个信息:
You've to pass -lgdi32 for the linker to know that you're using GDI functions. Also the order matters. On Windows 8 with MinGW 4.8.1 tool chain I give this:
- gle
- glfw3
- opengl32
- gdi32
它对我有用；我不包括其他win32库.如果您使用的是GLEW的静态库，请确保在CB中定义GLEW_STATIC或直接将其定义为-DGLEW_STATIC.
And it works for me; I don't include the other win32 libraries. If you're using GLEW's static library make sure you define GLEW_STATIC either in CB or directly as -DGLEW_STATIC.
对于IDE，我选择了带有CMake且没有Qt SDK的QtCreator.
As for the IDE, I chose QtCreator with CMake and with no Qt SDK.
