cmake升级

首先我感觉这个跟cmake的版本有关，最好先将cmake升级到3.17以上

root@VM-16-5-ubuntu:/home/ubuntu/lib/grpc# cmake --version
cmake version 3.18.0

下载cmake各版本安装包

下载地址：https://cmake.org/files/

选择需要的版本下载，我下载的是 v3.18 版本中的 Linux-x86_x64 一类后缀的版本，这个是已经针对 Linux 环境编译好的二进制包。比如我这里下载 cmake-3.18.0-Linux-x86_64.tar.gz。

上传到服务器后解压

tar -xzvf cmake-3.18.0-Linux-x86_64.tar.gz

将解压后的二进制包放到一个不会被你误删的地方

mv cmake-3.18.0-Linux-x86_64 /home/

找到原先低版本的cmake二进制包，将其拷贝备份到一个不会被你误删的地方

which cmake
/usr/bin/cmake
mv /usr/bin/cmake /home/cmake-3.18.0-Linux-x86_64/

创建软连接

sudo ln -s /home/cmake-3.18.0-Linux-x86_64/bin/cmake /usr/bin/cmake

注意这里一定要用绝对路径，不能用相对路径，不然不行。

然后运行cmake --version，cmake版本就变成你想要的版本啦。

grpc安装

git clone https://gitee.com/mirrors/grpc.git
cd grpc

替换.gitmodules文件

[submodule "third_party/zlib"]
	path = third_party/zlib
	url = https://gitee.com/Xprice/zlib.git
	# When using CMake to build, the zlib submodule ends up with a
	# generated file that makes Git consider the submodule dirty. This
	# state can be ignored for day-to-day development on gRPC.
	ignore = dirty

	path = third_party/benchmark

[submodule "third_party/abseil-cpp"]
	path = third_party/abseil-cpp

git submodule update --init
mkdir -p cmake/build
cd cmake/build
cmake ../..
make
sudo make install

这个命令不知道对结果是否有影响，建议执行一下

cp -r /home/ubuntu/lib/grpc/third_party/abseil-cpp/absl/ /usr/local/include/

protobuf安装

不用手动安装protobuf，不然版本可能不匹配，必须在 grpc 执行 git submodule update --init 命令之后生成的 third_party/protobuf 里面编译安装对应的 protobuf。

替换.gitmodules文件

[submodule "third_party/benchmark"]
	path = third_party/benchmark
	url = https://gitee.com/githubplus/benchmark.git
[submodule "third_party/googletest"]
	path = third_party/googletest
	url = https://gitee.com/githubplus/googletest.git
	ignore = dirty

cd third_party/abseil-cpp/
mkdir build
cd build
cmake ..
make
sudo make install

abseil安装

可能会有 abseil 的安装

cd third_party/protobuf/
./autogen.sh
./configure --prefix=/usr/local
make
sudo make install

---

测试环境

cd grpc/examples/cpp/helloworld/
mkdir build
cd build/
cmake ..
make
./greeter_server
Server listening on 0.0.0.0:50051
./greeter_client
