+# 如何构建Raspberry pi下运行的PaddlePaddle
+
+这里考虑的是交叉编译方式，即在Linux-x86环境下构建Raspberry pi下可运行的PaddlePaddle。
+
+## 下载交叉编译环境
+```
+git clone https://github.com/raspberrypi/tools
+```
+如果host是x86-64环境，选用`arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64`下的作为编译工具。注意，需要系统glibc支持2.14以上。
+
+
+## 编译第三方库
+cmake编译PaddlePaddle时候会自动下载编译依赖的第三方库，不过openblas和protobuf最好还是在编译PaddlePaddle之前先编译好，这样可以保证编译PaddlePaddle的时候更加顺畅。
+
+### 编译OpenBLAS
+```
+git clone https://github.com/xianyi/OpenBLAS.git
+make TARGET=ARMV7 HOSTCC=gcc CC=arm-linux-gnueabihf-gcc NOFORTRAN=1 USE_THREAD=0
+```
+
+### 编译protobuf
+```
+git clone https://github.com/google/protobuf.git
+git checkout 9f75c5aa851cd877fb0d93ccc31b8567a6706546
+cmake ../protobuf/cmake \
+-Dprotobuf_BUILD_TESTS=OFF \
+-DCMAKE_CXX_COMPILER=arm-linux-gnueabihf-g++ \
+-DCMAKE_C_COMPILER=arm-linux-gnueabihf-gcc \
+-DCMAKE_POSITION_INDEPENDENT_CODE=ON \
+-DCMAKE_BUILD_TYPE=Release \
+-DCMAKE_INSTALL_LIBDIR=lib
+```
+注意：这样编译出来的`libprotobuf.a`和`protoc`都是ARM版本的，而我们需要的是一个x86-64版本的`protoc`，所以需要用host gcc再编译一遍protobuf然后使用其中的`protoc`。
+
+
+## 编译PaddlePaddle
+cmake参数如下；其中`WITH_C_API`设置为ON，编译输出的output目录会中包含`include`和`lib`目录，其中`include`中包含CAPI的头文件，`lib`中包含一个ARM版本的库。另外，`CMAKE_BUILD_TYPE`设置为`MinSizeRel`可以减小编译的库的大小。
+```
+cmake .. -DWITH_GPU=OFF -DWITH_C_API=ON -DWITH_PYTHON=OFF -DWITH_SWIG_PY=OFF \
+-DCMAKE_CXX_COMPILER:FILEPATH=arm-linux-gnueabihf-g++ \
+-DCMAKE_C_COMPILER:FILEPATH=arm-linux-gnueabihf-gcc \
+-DCMAKE_C_FLAGS="-mfpu=neon" \
+-DCMAKE_CXX_FLAGS="-mfpu=neon" \
+-DOPENBLAS_ROOT=openblas \
+-DCMAKE_PREFIX_PATH=protobuf \
+-DCMAKE_BUILD_TYPE=MinSizeRel

+-DCMAKE_POSITION_INDEPENDENT_CODE=ON \
+-DCMAKE_BUILD_TYPE=Release \
+-DCMAKE_INSTALL_LIBDIR=lib
+```
+注意：这样编译出来的`libprotobuf.a`和`protoc`都是ARM版本的，而我们需要的是一个x86-64版本的`protoc`，所以需要用host gcc再编译一遍protobuf然后使用其中的`protoc`。
+
+
+## 编译PaddlePaddle
+cmake参数如下；其中`WITH_C_API`设置为ON，编译输出的output目录会中包含`include`和`lib`目录，其中`include`中包含CAPI的头文件，`lib`中包含一个ARM版本的库。另外，`CMAKE_BUILD_TYPE`设置为`MinSizeRel`可以减小编译的库的大小。
+```
+cmake .. -DWITH_GPU=OFF -DWITH_C_API=ON -DWITH_PYTHON=OFF -DWITH_SWIG_PY=OFF \
+-DCMAKE_CXX_COMPILER:FILEPATH=arm-linux-gnueabihf-g++ \
+-DCMAKE_C_COMPILER:FILEPATH=arm-linux-gnueabihf-gcc \
+-DCMAKE_C_FLAGS="-mfpu=neon" \
+-DCMAKE_CXX_FLAGS="-mfpu=neon" \
+-DOPENBLAS_ROOT=openblas \
+-DCMAKE_PREFIX_PATH=protobuf \
