1、安装相关依赖工具
#安装pkg-config
sudo apt-get install pkg-config
#安装依赖文件
sudo apt-get install autoconf automake libtool make g++ unzip
sudo apt-get install libgflags-dev libgtest-dev
sudo apt-get install clang libc++-dev
2、下载gRPC 源码
git clone https://github.com/grpc/grpc.git
cd grpc
git submodule update –init #更新第三方源码
3、编译安装protobuf.
cd third_party/protobuf
./autogen.sh
./configure
make && make check && sudo make install && sudo ldconfig
4、编译安装grpc
cd grpc
make && sudo make install && sudo ldconfig
5、清除当前编译文件
make clean
6、指定交叉编译环境变量
export GRPC_CROSS_COMPILE=true
#32位环境
export GRPC_CROSS_AROPTS=”cr –target=elf32-little”
#64位环境
export GRPC_CROSS_AROPTS=”cr –target=elf64-little”
7、开始交叉编译，将grpc编译为静态
make HAS_PKG_CONFIG=false \
CC=aarch64-linux-gnu-gcc \
CXX=aarch64-linux-gnu-g++ \
RANLIB=aarch64-linux-gnu-ranlib \
LD=aarch64-linux-gnu-ld \
LDXX=aarch64-linux-gnu-g++ \
AR=aarch64-linux-gnu-ar \
PROTOBUF_CONFIG_OPTS=”–host=aarch64-linux-gnu –with-protoc=/usr/local/bin/protoc” static
