Hi Yan, 

It looks like our makefiles require special environment variables to be set in the specific format. Please, define the NDK_ROOT=$PATH_TO_NDK/android-ndk-$(ndk_version) and a path to adb (in order to be able to run tests on a device). Report, if you have any problems.

Thanks,

Nikita

I found .so files later on ubuntu. But on Windows it doesn't work even with defined NDK_ROOT. I got the same error:

I tried to compile in ./ , /jni and /src results are same.

From the log, it seems like your $(ndk_version) variable is not parsed correctly. "NDK version C:" should be something like that "NDK version 16". For that reason, make cannot find "windows_arm_clang_android_NDKC:_version_android-21_release" folder. Could you, please, check and provide the value of NDK_ROOT and ndk_version from Android.mk (35-38 lines) file? Compilation from tbb_root is enough.

Ok, I recently renamed my android-ndk-r15c folder to ndk, I manually set ndk_version to r15c and now it starts compiling. 
But it can't compile some files properly:

I see only some strange problem with test_malloc_used_by_lib, however, the library was built correctly.

Just use this command if you don't need tests.

ndk-build tbb tbbmalloc arch=arm target=android tbb_os=windows compiler=clang -j -B

Thanks a lot.
Library compiled, but what about test_malloc_used_by_lib? Bug?
