1.I create cross compile by Androd NDK 2.referring to https://docs.opencv.org/master/d0/d76/tutorial_arm_crosscompile_with_cmake.html first , I change CMAKE_C/XX_COMPILER using cross compile by Androd NDK, then cmake -DCMAKE_TOOLCHAIN_FILE=../arm-gnueabi.toolchain.cmake ../../.. 3.I meet this error ,and don't know how to solve it.
