OSError: [Errno 2] No such file or directory when python build.py

[serrokitskiy]

I'm following your instructions, but when doing '$ python build.py' I get:

$ vim ~/.bashrc

when I try '$ ndk-build' I get

@serrokitskiy , It seems that you didn't set up ndk correctly. Can you go to your ndk home to check if there is 'ndk-build' binary? If not, I suggest that you can download ndk from here. Download NDK from official website https://developer.android.com/ndk/downloads/index.html

[serrokitskiy]

@tzutalin , I downloaded the NDK from the site. But nothing changed(((

Do I need to change the NDK_PATH in the script?

[serrokitskiy]

i will try $ bash than $ ndk-build and than $ python build.py

Hi @serrokitskiy , You have built it successfully. You can ignore the error. The error is caused because you didn't setup Android SDK, it cannot Android 'adb' tool.

[serrokitskiy]

@tzutalin , Good. And how can I test the work of this library? Is there any code with which I can do this?

I've solved same problem. You need to add path to adb in bashrc like this. export PATH=$PATH:/Users/Beomseok/Library/Android/sdk/platform-tools

Have you solved this problem? I'm still confused about it, both using build.py and using cmakelist.txt.

CMake Error at CMakeLists.txt:36 (add_library): Cannot find source file:

I have solved the problem,but faced with new one by using ndk-build -j 2 : clang++: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [obj/local/arm64-v8a/libandroid_dlib.so] Error 1

Hi! @ElliotQi I am having the same issue as you mentioned with calling ndk-build by build.py. could you please explain how you got it solved? Thanks in advance!!
