Opencv 2.3.0 Flann链接错误（Xcode）

我有一个较旧的系统（OSX 10.6.8与xcode 4.0），我试图让OpenCV 2.3.0在它上面工作。我无法解决的问题是，每当我尝试使用flann库时，我的xcode都会给我一个Mach-O链接器错误。到目前为止，我已经尝试重新编译所有库并从不同的来源构建dylib，但它没有帮助。当我检查在终端库，我得到Opencv 2.3.0 Flann链接错误（Xcode）

Freddi-2:OpenCV-2.3.0 fredchen$ file /usr/local/lib/libopencv_flann.dylib 
/usr/local/lib/libopencv_flann.dylib: Mach-O 64-bit dynamically linked shared library x86_64

我的具体错误代码是：

Undefined symbols for architecture x86_64: 
    "cv::flann::KDTreeIndexParams::KDTreeIndexParams(int)", referenced from: 
    _main in main.o 
    "cv::flann::SearchParams::SearchParams(int, float, bool)", referenced from: 
    _main in main.o 
    "cv::FlannBasedMatcher::FlannBasedMatcher(cv::Ptr<cv::flann::IndexParams> const&, cv::Ptr<cv::flann::SearchParams> const&)", referenced from: 
    _main in main.o 
    "cv::BFMatcher::BFMatcher(int, bool)", referenced from: 
    _main in main.o 
    "cv::flann::IndexParams::~IndexParams()", referenced from: 
    cv::flann::SearchParams::~SearchParams() in main.o 
    "cv::flann::IndexParams::~IndexParams()", referenced from: 
    cv::Ptr<cv::flann::IndexParams>::delete_obj() in main.o 
    "vtable for cv::BFMatcher", referenced from: 
    cv::BFMatcher::~BFMatcher() in main.o 
ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我已经与项目挂钩的动态库是：

libopencv_video.2.3.0.dylib 
libopencv_objdetect.2.3.0.dylib 
libopencv_ml.2.3.0.dylib 
libopencv_legacy.2.3.0.dylib 
libopencv_gpu.2.3.0.dylib 
libopencv_contrib.2.3.0.dylib 
libopencv_ts.2.3.0.dylib 
libopencv_imgproc.2.3.0.dylib 
libopencv_highgui.2.3.0.dylib 
libopencv_flann.2.3.0.dylib 
libopencv_features2d.2.3.0.dylib 
libopencv_core.2.3.0.dylib 
libopencv_calib3d.2.3.0.dylib

我d感谢任何帮助。谢谢！

我记得我在Mac上使用2.3.0时遇到了类似的错误。你应该尝试使用最新版本，2.4.4或github的最新版本。
