Regarding build issues, please try to use docker for simplicity.

[Qvodman]

@sh1r0 I already use docker.

[sh1r0]

@Qvodman Could you show me the command you use?

[Qvodman]

@sh1r0
git clone --recursive https://github.com/sh1r0/caffe-android-lib.git

cd caffe-android-lib

sudo docker build -t caffe-android-lib .

sudo docker run --rm --name caffe-android-builder -e ANDROID_ABI=x86_64 -e N_JOBS=2 -v $(pwd)/android_lib/x86_64:/caffe-android-lib/android_lib caffe-android-lib ./build.sh

[Qvodman]

@sh1r0 And when I used:

git clone --recursive https://github.com/sh1r0/caffe-android-lib.git

cd caffe-android-lib

sudo docker build -t caffe-android-lib .

sudo docker run --rm --name caffe-android-builder -e ANDROID_ABI=arm64-v8a -e N_JOBS=2 -v $(pwd)/android_lib/arm64-v8a:/caffe-android-lib/android_lib caffe-android-lib ./build.sh

The problem:

Hi @Qvodman, I just did a clean clone, re-created the docker image, and used the command below.

docker run --rm --name caffe-android-builder \
     -e ANDROID_ABI=arm64-v8a \
     -e N_JOBS=2 \
     -v $(pwd)/android_lib/arm64-v8a:/caffe-android-lib/android_lib \
     caffe-android-lib ./build.sh

Per log (listed below), OpenBLAS is successfully built and installed.

Could you provide more details about your environment?

[Qvodman]

@sh1r0
Ubuntu 16.04.02
cmake version 3.5.1
NDK:android-ndk-r11C

[sh1r0]

Hi @Qvodman, I pulled the latest ubuntu:16.04 docker image and tested again without failures. Would you like to re-pull the docker image?

[Qvodman]

@sh1r0 Do I need to install OpenBLAS by myself?

[sh1r0]

Nope, everything should be self-contained in this project.
