Compile OpenBLAS for Android problem

[ghost]

Hi, xianyi,

I am using Ubuntu to compile OpenBLAS for Android platform, and follow exactly the command:

export PATH=/tmp/my-android-toolchain/bin:$PATH

make HOSTCC=gcc CC=arm-linux-androideabi-gcc NO_LAPACK=1 TARGET=ARMV7

by changing the right toolchain path. But make complains that it cannot find "stdio.h" which I think is located in NDK Android platform folder, in my case, is android-ndk-r10e/platforms/android-19/arch-arm/usr.

Could you tell me how to modify the Makefile to let it find the right Android platform dependency? It is too complicated for me to do it myself. Thanks a lot.

I think I have found the answer [1]. Do not know how to delete this issue. Sorry.

I was able to build libopenblas.so for Android using the below simple commands,

Step 1: Install standalone toolchain as given here (Choose your API level accordingly)
Step 2: export PATH=$PATH:/your/toolchain_dir/bin/
Step 3: Make OpenBLAS using the below make command
make TARGET=ARMV8 ONLY_CBLAS=1 AR=aarch64-linux-android-ar CC="aarch64-linux-android-clang" HOSTCC=gcc -j4

Thanks,
San
