Please tell us about your environment:

• System: Macos

• Compiler version/IDE: gcc4.2.1

• CMake version: 3.7.1

• OpenCV version: 3.1

编译通过了，做了如下修改：
chars_identify.cpp
load去掉<ml::ANN_MLP>
plate_judge.cpp
load去掉<ml::SVM>
svm_train.cpp
load去掉<cv::ml::SVM>

• System: macOS 10.12.1
• Compiler version/IDE: Apple LLVM version 8.0.0
• CMake version: 3.7.1
• OpenCV version: 3.2

自己不太懂这个，但是 为什么 这样改就是可以的呢？

错误 143 error LNK2038: 检测到“RuntimeLibrary”的不匹配项: 值“MD_DynamicRelease”不匹配值“MT_StaticRelease”(main.obj 中) E:\OpenCV\EasyPR-master\vcprojs\libeasypr.lib(plate_detect.obj) demo

环境为vs2013,openCV3.2,在进行release编译时出现这种情况，debug编译已经通过。

[liuruoze]

release版对应的opencv的库需要调整的

[itriphaxer]

error LNK2038: 检测到“RuntimeLibrary”的不匹配项: 值“MT_StaticRelease”不匹配值“MD_DynamicRelease”

在工程上右键-》属性-》c/c++-》代码生成-》运行库
改成（release为MD，debug为MDd）即可解决

Opencv3.2版本的支持，编译前仅需要将config.h中将#define CV_VERSION_THREE_ZERO改为#define CV_VERSION_THREE_TWO即可。

/include/easypr/config.h
-#define CV_VERSION_THREE_ZERO
+// #define CV_VERSION_THREE_ZERO
+#define CV_VERSION_THREE_TWO

@ZhangXinNan thank you ! fixed it!

[Lucas-Yang]

@ZhangXinNan +1 fixed it

通过自动判断OpenCV版本号彻底解决该问题：#286
