How to get the permission in NDK

I am new to Android NDK and I have to use OpenCV in Android.

I tried to ran the NDK ahead , but these errors happened. Maybe I have no permission to use the file" /obj/local/armeabi/libopencv_contrib.a",How can I get the permission? And can the next error be OK when the first error is solved? My workspace OS is Windows7. 

$ NDK-build

SharedLibrary : libImgFun.so D:/Android/android-ndk-r7b-windows/android-ndk-r7b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/../lib/gcc/arm-linux-androideabi/4.4.3/../../../../arm-linux-androideabi/bin/ld.exe: ./obj/local/armeabi/libopencv_contrib.a: No such file: Permission denied

collect2: ld returned 1 exit status /cygdrive/d/Android/android-ndk-r7b-windows/android-ndk-r7b/build/core/build-binary.mk:314: recipe for target `obj/local/armeabi/libImgFun.so' failed make: * [obj/local/armeabi/libImgFun.so] Error 1

I had the same problem on Windows 7. I was able to just use chmod to set the permissions manually, and then it worked. My best guess is that this is a bug with how Cygwin, Windows, and the build process interact.

  • Open a console window
  • > bash
  • > cd /cygdrive/<driveletter>/<wherever your project is>/obj/local/armeabi
  • > chmod 777 ./*
