我正在尝试为 opencv 运行 cmake_android.cmd 脚本,详见此处: http ://opencv.willowgarage.com/wiki/Android2.3.0#Windows_.28native.29

所以我可以得到一个 OpenCV.mk 文件与 Android 一起使用

所以我启动 cmd.exe 当我在opencv\android 运行时scripts\cmake_android.cmd

它达到大约 3% 并失败,因为它找不到 iostream

[  3%] Building CXX object 3rdparty/libtiff/CMakeFiles/libtiff.dir/tif_stream.cxx.o
C:\opencv\3rdparty\libtiff\tif_stream.cxx:31:20: error: iostream: No such file or directory

这是我的 wincfg.cmd 文件

:: variables required for OpenCV build ::
:: Note: all pathes should be specified without tailing slashes!
SET ANDROID_NDK=C:\android-ndk-r8b-windows\android-ndk-r8b

:::: uncomment following lines to compile for x86

::SET BUILD_DIR=build_x86

:::: other options
::SET ANDROID_NATIVE_API_LEVEL=8   &:: android-3 is enough for native part of OpenCV but android-8 is required for Java API

非常感谢任何帮助!

对于 NDK r8b,您需要来自存储库的最新 OpenCV。

OpenCV 2.4.2 版本支持从 r5 到 r8 的 NDK。来自 sourceforge 和 Google Play 的预构建 Android 二进制文件是使用 NDK r8 编译的。
