OpenCV 2.3不编译，未定义的引用错误 [英] OpenCV 2.3 doesn't compile, undefined reference error
本文介绍了OpenCV 2.3不编译，未定义的引用错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在Windows 7 64bits和Netbeans 7.0中使用OpenCV。我试图编译使用MinGW和cygwin的，但都失败未定义的引用下一个代码。
当我用垫或FLANN和其他人，我不能编译，但我添加所有的库（我试图只添加调试，发布，只需要一个...但失败）。
ubuntu的同样的代码，在Windows中编译它。我使用2.3编译版本（使用CMake）和可安装的版本。

解决方案使用预编译MinGW库？ （它看起来如此）。我试了几天，让我的项目成功链接在Code :: Blocks下。我看到你描述的相同种类的错误（错误的引用等）。
我最后使用显示的步骤重新编译OpenCV 这里，一切顺利。
I'm using OpenCV in Windows 7 64bits and Netbeans 7.0. I tried to compile the next code using MinGW and cygwin but both fails with undefined references.
When I use MAT or FLANN and others I can't compile, but I'm adding all libraries (I tried only adding Debug ones, Release ones, only needed ones... but fails).
The same code in ubuntu works, but I need to compile it in windows too. I'm using the 2.3 compiled version (using CMake) and the installable one.

same result.
解决方案 Are you using the precompiled MinGW libraries? (it appears so). I tried for a couple of days to get my project to link successfully under Code::Blocks. I was seeing the same sort of errors you describe (bad references, etc).
I finally recompiled OpenCV using the steps shown here, and all became well.
