如何在OS X上使用额外的模块编译OpenCV? [英] How to compile OpenCV with extra modules on OS X?

问题描述

我以前在本指南，该指南主要由以下步骤组成:

I've previously compiled OpenCV 3.0 successfully following this guide, which essentially consists of the following steps:

• 下载所有先决条件(XCode，命令行工具，CMake和OpenCV源代码)
• 通过配置CMake(通过gui)来构建静态库:
  • 取消选中 BUILD_SHARED_LIBS
  • 取消选中BUILD_TESTS
  • 将SDK路径添加到CMAKE_OSX_SYSROOT(如果重要的话，我使用了/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk ).
  • 将x86_64添加到CMAKE_OSX_ARCHITECTURES (重点是我，这似乎是问题所在，我确定我已经遵循了此步骤)
  • 取消选中WITH_1394
  • 取消选中WITH_FFMPEG
  • Download all the prerequisites (XCode, Command Line Tools, CMake and OpenCV source)
  • Build static libs by configuring CMake (via gui) with:
    • Uncheck BUILD_SHARED_LIBS
    • Uncheck BUILD_TESTS
    • Add an SDK path to CMAKE_OSX_SYSROOT (if it matters, I used /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk).
    • Add x86_64 to CMAKE_OSX_ARCHITECTURES (emphasis mine, this seems to be the issue, I'm sure I've followed this step)
    • Uncheck WITH_1394
    • Uncheck WITH_FFMPEG

    仅上述所有方法都可以正常工作.

    All of the above alone works fine.

    我现在正在寻找使用其他模块编译OpenCV.根据他们的自述文件，它应该很简单，只需将 OPENCV_EXTRA_MODULES_PATH 填写到CMake中的< opencv_contrib>/modules ，然后照常进行构建即可.

    I'm now looking to compile OpenCV with the extra modules. According to their read-me it should be as simple as filling out OPENCV_EXTRA_MODULES_PATH to <opencv_contrib>/modules in CMake and then building as usual.

    我按照上面概述的步骤添加了参数，但是，当尝试在程序中使用其他模块之一(即 cv :: ximgproc :: createStructuredEdgeDetection 时)，构建OpenCV成功了很重要)，编译时出现以下错误:

    I followed the steps outlined above with the added parameter and building OpenCV succeeds, however, when trying to use one of the extra modules in a program (namely cv::ximgproc::createStructuredEdgeDetection, if it matters), I'm getting the following error when compiling:

    x86_64体系结构的未定义符号:
    "cv :: ximgproc :: createStructuredEdgeDetection(cv :: String const& ;, cv :: Ptr< cv :: ximgproc :: RFFeatureGetter const>)" ，引用自:_main in main.o
    ld:找不到架构x86_64的符号
    clang:错误:链接器命令失败，退出代码为1(使用-v查看调用)

    Undefined symbols for architecture x86_64:
    "cv::ximgproc::createStructuredEdgeDetection(cv::String const&, cv::Ptr<cv::ximgproc::RFFeatureGetter const>)", referenced from:
    _main 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)

    我已包含标题，其中应包含以上内容:

    I've included the header which should include the above:

    #include <opencv2/ximgproc.hpp>
    

    我正在通过XCode进行编译，在其中我设置了/usr/local/include 的附加头搜索路径和/usr/local/lib <的库搜索路径/code>该项目，我在这里遗漏了什么吗?

    I'm compiling via XCode, where I've set an additional header search path of /usr/local/include and a library search path of /usr/local/lib for the project, am I missing something here?

    标准OpenCV功能正常.

    Standard OpenCV functionality works fine.

    可能是什么问题，我将如何解决?

    What could be the issue and how would I go about solving it?

    推荐答案

    OpenCV contrib模块已正确构建.

    OpenCV contrib modules are built correctly.

    您只需要将contrib库添加到您的依赖项中，在这种情况下，添加: -lopencv_ximgproc .

    You just need to add the contrib libs to your dependencies, in this case adding: -lopencv_ximgproc.

    所有可用的库都可以在< OPENCV_DIR>/install/文件夹下找到.例如.我的32位vc12静态版本中的< OPENCV_DIR>/install/x86/vc12/staticlib 文件夹中.

    All available libs can be found under <OPENCV_DIR>/install/ folder. E.g. in my 32bit vc12 static build are in<OPENCV_DIR>/install/x86/vc12/staticlib folder.
