Windows下的CMake OpenCV進行Android的......找不到的iostream

Question

我試圖運行的OpenCV的cmake_android.cmd腳本詳見這裏： http://opencv.willowgarage.com/wiki/Android2.3.0#Windows_.28native.29

這樣我就可以得到一個OpenCV.mk文件與Android

使用

於是我開始cmd.exe的 當我在opencv\android 我跑scripts\cmake_android.cmd

它得到約3％，因爲它無法找到的iostream失敗

[ 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 

這是我wincfg.cmd文件

:: variables required for OpenCV build ::

SET ANDROID_NDK=C:\android-ndk-r8b-windows\android-ndk-r8b

:::: uncomment following lines to compile for ARM-V7 with NEON support

::SET BUILD_DIR=build_neon 

:::: uncomment following lines to compile for x86 
::SET ANDROID_ABI=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 

任何援助不勝感激！

對於NDK r8b，您需要存儲庫中的最新OpenCV。

OpenCV 2.4.2發行版支持從r5到r8的NDK。並且使用NDK r8編譯來自sourceforge和Google Play的預生成Android二進制文件。
