时间紧，先大概说明一下，有时间了再补充详细的说明

grpc 交叉编译 需要先编译出pc版的protobuff 和 grpc，安装到指定的路径，在做交叉编译时需要protoc 和grpc_cpp_plugin工具。这两个工具也也是在编译时会生成，交叉编译过程中要屏蔽掉使用交叉编译后的工具。

先上配置

#! /bin/sh

export HOST=arm-hisiv400-linux
export CROSS=arm-hisiv400-linux-
export CC=${CROSS}gcc
export AR=${CROSS}ar
export CPP=${CROSS}cpp
export CXX=${CROSS}g++
export STRIP=${CROSS}strip
export RANLIB=${CROSS}ranlib

export CFLAGS=-I$PWD/build/include
export LDFLAGS=-L$PWD/build/lib
export PREFIX=$PWD/build
export SYS_INCLUDE_ROOT=/opt/hisi-linux/x86-arm/arm-hisi400-linux/target

cd grpc-1.14.1
./build.sh && make clean && make && make install
cd -

 

 

CMakeLists.txt.pre 我将原始的CMakeLists.txt备份成了CMakeLists.txt.pre

sed指令为了使用x86 平台上的工具

cp ./CMakeLists.txt.pre ./CMakeLists.txt;\
rm CMakeCache.txt;    \
sed -i 's/$<TARGET_FILE:grpc_cpp_plugin>/\.\.\/build\/x86\/bin\/grpc_cpp_plugin/g' CMakeLists.txt;
cmake  -G "Unix Makefiles"     -DCMAKE_INSTALL_PREFIX=${PREFIX} \

                        -DLINK_LIBRARIES:STRING=${PREFIX}/lib \
                        -DCMAKE_C_COMPILER=${CC} -DCMAKE_CXX_COMPILER=${CXX} \

编译到48%报错如下

将
