Unable to run .build.py $(NDK_PATH)

[nikogamulin]

I tried to clone the Caffe-Android-Lib code and build it. Running git clone --recursive

Anyway, lately I noticed that included Boost-for-Android does not support NDK version 10d - 64bit. Therefore I added the version from the repository https://github.com/MysticTreeGames/Boost-for-Android.

When running ./build.py $(NDK_PATH), I first got an error and fixed it by running make all in folder caffe-android-lib/caffe-mobile/jni/caffe/ and then copying the following files:

cp -r caffe-android-lib/caffe-mobile/jni/caffe/.build_release/src/caffe/proto/* caffe-android-lib/caffe-mobile/jni/caffe/src/caffe/proto/

Then, after running ./build.py $(NDK_PATH) I got the following error:

Android NDK: WARNING:/usr/local/caffe-android-lib/caffe-mobile/jni/Android.mk:caffe: non-system libraries in linker flags: -lboost_random-gcc-mt-1_55 -lboost_math_tr1-gcc-mt-1_55 -lboost_system-gcc-mt-1_55 -lboost_thread-gcc-mt-1_55

I tried to fix the error by running the following:

wget https://github.com/schuhschuh/gflags/archive/master.zip
unzip master.zip
cd gflags-master
mkdir build && cd build
export CXXFLAGS="-fPIC" && cmake .. && make VERBOSE=1
make 
sudo make install

Unfortunately, I haven't managed to come any further and haven't figured out the cause of the problem.

As I couldnt build the model with modified caffe version (Caffe-Android-Lib), I built the model with official caffe version and uploaded the files to sd card:

adb shell mkdir -p /sdcard/caffe_mobile/
adb push caffe/data/ilsvrc12/imagenet_mean.binaryproto /sdcard/caffe_mobile/
adb push caffe/models/bvlc_reference_caffenet/ /sdcard/caffe_mobile/bvlc_reference_caffenet/

When I tried to run caffe-android-demo, the app crashed with the following error:

com.sh1r0.caffe_android_demo A/libc﹕ Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 1250 (AsyncTask #1)

I would appreciate if anyone could help out finding the cause of the problem and solve it.

Hi @nikogamulin ,
I just updated the remote urls of the submodules, and also my Boost-for-Android to the lastest version for supporting android-ndk-r10d. So now, it should be okay to run ./build.py $(NDK_PATH) without toolchain issues. (You can cleanly clone agian. I tested the updates by using android-ndk-r10d-linux-x86_64.bin.)

The errors about proto files and gflags may caused by using the wrong caffe branch. I recommend you to cleanly clone again.

For the model part, you can download the stuff you need by simply running ./get_model.py.

Thanks.

Excellent! Everything works perfectly now!
