TBB 4.1 update 3 for Android

[Riccardo_Ancona]

Hi everyone,

I am having some difficulties in following the tutorial at http://software.intel.com/en-us/articles/android-tutorial-writing-a-multithreaded-application-using-intel-threading-building-blocks using TBB 4.1 update 3 source files and NDK r8e.

From the first rows, I noticed that there is no <unpacked_dir>/build/android_setup.csh script to be executed, I noticed that the compiling guidelines say that I have to build the library using ndk-build target=android, but I don't understand if the build is successful because there is a huge number of ignored errors like:

make[1]: [malloc_test_no_depends] Error 1 (ignored)
sh ../../build/android.linux.launcher.sh ./test_malloc_atexit.exe
/system/bin/sh: ./test_malloc_atexit.exe: not executable: magic 7F45

and at the end of the built I got:

So, how can I compile TBB library for armeabi-v7a architecture?

 But most of all, where I can find  Android documentation for TBB? That tutorial is too old! Is there an updated tutorial for Android quickstart with TBB?

hello Riccardo,

You can find a sample to build app for android in parallel_for/tachyon example. Its android makefiles are aligned with NDK spec.

the command line to build the library is

[bash]
ndk-build target=android tbb
[/bash]

For armeabi-v7a 

[bash]
ndk-build target=android tbb arch=arm
[/bash]

--Vladimir

Thank you SO much :) Now all is working and I am running TBB on android!

Thanks a lot!
