你好，看之前的问题，找到一个x86文件夹下的so库，但是这里报错要x86_64下面的so库，我编译通不过了，这个有没有别的办法可以解决的？

我将ndk的版本降低到17就编译成功了，你们可以试一试

[gitgeek4dx]

不需要降低ndk版本，cmake最后一段，这样改下可以了，ndk21编译正常：

find_library( # Sets the name of the path variable. log-lib # Specifies the name of the NDK library that # you want CMake to locate. log )

target_link_libraries( # Specifies the target library. ${TARGET} android # Links the target library to the log library # included in the NDK. ${log-lib} jnigraphics z)

if(${ANDROID_ABI} STREQUAL x86 OR ${ANDROID_ABI} STREQUAL x86_64) target_link_libraries(${TARGET} opencv_imgproc opencv_core ippiw ippicv ittnotify tbb cpufeatures) else() target_link_libraries(${TARGET} opencv_imgproc opencv_core tegra_hal tbb cpufeatures) endif()
