由于opencv_contrib，我不得不从源代码中构建opencv。尽管我尝试过许多教程，但我还是失败了，无法从源代码构建opencv。

我使用的代码：

代码语言：javascript
运行
复制
cmake -G"MinGW Makefiles" -DANDROID_NDK=D:/androidNDK/android-ndk-r22b -DANDROID_SDK_ROOT=D:/android-sdk -DCMAKE_TOOLCHAIN_FILE=D:/androidNDK/android-ndk-r22b/build/cmake/android.toolchain.cmake -DBUILD_EXAMPLES=OFF -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=OFF D:/OpenCV455/opencv-4.5.5

一般配置：

怎么修呢？

我试图为类似的问题找到解决方案，这里可能是唯一类似的一。开发人员认为：

Android :不使用，在完全跳过基于Java的项目的消息之后，项目就不会生成。尝试升级你的Android "BuildTools“。CMAKE_CONFIG_GENERATOR="MinGW Makefiles“在Android中有忍者构建工具。使用cmake -GNinja ..。为了更好的经验。我不太了解如何做，我的构建工具版本是33.0.0。

我找到了两个选择：

  1. 外壳脚本 (参考文献)
  • 安装Git Bash并在PATH (C:\Program Files\Git\cmd)中设置它
  • 安装Cmake 3.24.3并在PATH (C:\Program Files\CMake\bin)中设置它
  • 安装java并在PATH (C:\Program Files\Java\jdk1.8.0_202\bin)中设置它，创建变量JAVA_HOME(C:\Program Files\Java\jdk1.8.0_202)
  • 安装C编译器(明威或Visual Studio等)。如果使用mingw，则需要安装：mingw32-base-bin、mingw32-gcc-fortran-bin、mingw32-gcc-g++-bin、mingw32-gcc-objc-bin、msys-base-bin。然后在PATH中添加C:\MinGW\bin
  • 您可能也需要WSL for Windows，但我只是通过Git Bash完成的
  • 在空文件夹中创建脚本并将其命名为build.sh

  • 打开Git，打开包含脚本的文件夹并编写bash build.sh
  • 如果您有以下错误syntax error: unexpected end of file，则这里是解决方案
  • 因此，我们得到了opencv_java460.dll和opencv-460.jar
  1. Cmake与忍者(取自这里，但已修改)

在这里，我将描述我以前构建的内容(这并不是我所需要的全部或特定的版本，但它对我是有效的)：

  • 安装Python并在PATH (C:\Users\volce\AppData\Local\Programs\Python\Python311\Scripts\иC:\Users\volce\AppData\Local\Programs\Python\Python311\)中设置它
  • 安装java 8并在PATH和JAVA_HOME中设置它(见上文)
  • 安装Cmake 3.24.3 (我还没有在其他版本上尝试过)并在PATH中设置它(见上文)
  • 下载NDK r25，解压缩并添加环境变量ANDROID_NDK: C:\Users\volce\AppData\Local\Android\Sdk\ndk\android-ndk-r25b
  • 下载SDK工具r25.2.3，平台-工具r25.0.1和构建工具r25.0.1
  • 在SDK文件夹中，将tools、build-tools和platform-tools文件夹的内容替换为下载的文件夹。
  • 另外，在PATH中我添加了：C:\Users\volce\AppData\Local\Android\Sdk\tools和C:\Users\volce\AppData\Local\Android\Sdk\platform-tools
  • 添加环境变量：ANDROID_HOME和ANDROID_SDK_ROOT，其中我们指定到SDK的路径(例如，C:\Users\volce\AppData\Local\Android\Sdk)
  • 下载ant并将其设置为PATH (C:\apache-ant-1.10.12\binиC:\apache-ant-1.10.12\lib)并创建ANT_HOME (C:\apache-ant-1.10.12)
  • 下载MinGw，安装必要的软件包并在PATH中设置它(见上文)
  • 下载和安装Visual Studio

我接下来做了什么

  • 为我们的任务创建一个文件夹
  • 在它中我们做git clone https://github.com/opencv/opencv.git和git clone https://github.com/opencv/opencv_contrib.git
  • 在带有opencv的文件夹中，转到samples\android，并在CMakeLists.txt文件中删除add_subdirectory(15-puzzle) (因此，我没有构建)
  • 在根文件夹中创建一个build文件夹(它是为构建opencv创建的)
  • 我们进入它并做git clone https://github.com/ninja-build/ninja.git
  • 打开。在它中:工具->命令行->开发人员命令行。在命令行中，将路径写入创建的文件夹build并写入python configure.py --bootstrap。这就是我们配置ninja的方式
  • 在控制台的build文件夹中，我们编写了以下内容(不要忘记更改到您自己的的路径)：
