My host machine is ubuntu 16.04. And PaddlePaddle for host following this can be successfully built.

Now I wanted to build PaddlePaddle for Raspberry Pi following this guide. I used this command to build PaddlePaddle:

cmake -DCMAKE_SYSTEM_NAME=RPi  -CMAKE_INSTALL_PREFIX=/home/zfq/Paddle/build/CAPI_ACL_RPi  -DCMAKE_BUILD_TYPE=Debug -DWITH_C_API=ON  -DWITH_SWIG_PY=OFF -DRPI_TOOLCHAIN=/home/zfq/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64   -DWITH_GPU=OFF   -DWITH_PYTHON=OFF ..

And then encountered the error:

/home/zfq/Paddle/build/third_party/snappy_stream/src/extern_snappystream/src/osnappystream.cpp:11:20: fatal error: snappy.h: No such file or directory #include "snappy.h"

I found the "snappy.h" at third_party/snappy/src/extern_snappy, so I modified the #include by using absolute path as a workaround.

But after this I met this error:

/home/zfq/Paddle/build/third_party/snappy/src/extern_snappy/snappy.h:45:33: fatal error: snappy-stubs-public.h: No such file or directory #include "snappy-stubs-public.h"

I also solved it by modified #include.

After this I met this:

/home/zfq/Paddle/paddle/math/MathFunctions.h:39:19: fatal error: cblas.h: No such file or directory #include <cblas.h>

Now I am confused, does anyone know why? Maybe the raspberry_pi.cmake has some problem? Thank you in advance!
