Can't compile TBB for ARM

[Malyavko__Yan]

Can't compile TBB for ARM on windows and ubuntu.
TBB ver.: 2018_U4
NDK: 15c 

Windows: 

Ubuntu:

It compiles about 5 minutes and stops after fibonacci test. It doesn't make any .so files in build folder.  

Ubuntu log's attached.

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?
