Ubuntu20.04(arm)+Qt5.12.8+gRPC1.48 编译与使用_ubuntu20.04 arm64 qt5

本文章参考了多位大佬与gRPC官方的文章，在此拜谢，以下仅为本人自己的编译过程与使用的分享，如有错误，还望指正。

gRPC在ubuntu系统下的安装和使用https://blog.csdn.net/w13l14/article/details/117984322gRPC官方https://grpc.io/docs/languages/cpp/quickstart/ubuntu20.04 编译安装 grpc-c++https://blog.csdn.net/Bart__/article/details/106992395#:~:text=%E7%BC%96%E8%AF%91%E5%AE%89%E8%A3%85grpc%20%23%E5%AE%89%E8%A3%85%E4%BB%A5%E4%B8%8B%E7%BB%84%E4%BB%B6%20%24%20sudo%20apt-get%20install%20build-essential%20autoconf,%23%E7%BC%96%E8%AF%91%E5%AE%89%E8%A3%85grpc%E5%BA%93%20%24%20mkdir%20-p%20cmake%2Fbuild%20%24%20pushd%20cmake%2Fbuild

1、环境/工具

(1)Ubuntu 20.04(arm)

(2)Qt 5.12.8

(3)CMake 3.28.3

(4)Git

(5)GCC/G++ 9.4.0

注意：gRPC对CMake与GCC/G++版本有所要求，最好能够升级到较高的版本，具体的升级方法请查阅网上资料，本人在这里只升级了CMake，故在下方只列出CMake的升级文章

ubuntu18.04的cmake升级https://blog.csdn.net/Boys_Wu/article/details/104940575

 2、安装编译工具

在ubuntu中打开终端，输入以下代码，安装gRPC的编译工具

$ sudo apt install -y build-essential autoconf libtool pkg-config

另外，本人额外安装了libssl-dev工具，不知道有啥用，先记录进来

$ sudo apt-get install libssl-dev 

3、下载gRPC（1.48版本）

具体参照我之前的文章，中第4章（1）中的内容。windows+vs2017 C++编译gRPChttps://blog.csdn.net/weixin_44328139/article/details/136504504?spm=1001.2014.3001.5502注意：仅下载gRPC代码，必须下载完全，（可以重复执行   git submodule update --init --recursive    命令，直到没有错误提示）。

之后将源码目录下third_party\zlib\CMakeList.txt的第一行依赖的CMake版本修改为2.8.12；

4、使用CMake编译gRPC

（1）创建编译文件夹build

进入刚刚git clone 下来的grpc目录，使用以下代码，创建文件编译文件夹

mkdir arm64_build

（2）编译gRPC

        1.进入创建的文件夹

cd arm64_build

        2.使用以下代码进行编译设置

cmake -DgRPC_INSTALL=ON -DCMAKE_BUILD_TYPE=Release -DgRPC_BUILD_TESTS=OFF -DCMAKE_INSTALL_PREFIX=/home/nvidia/workspace/grpc/GRPCPACKAGE -DgRPC_SSL_PROVIDER=package ..

        注意：最后有 “..” 

        3.执行以下代码编译，等待编译完成

make -j 8

        注意：编译过程中是否存在红色报错，waring信息忽略，若存在报错，可能是git clone代码下载不完全，若确认代码下载完全，则可网上查找相关错误问题。

（3）安装gRPC

make install

        通过此条代码进行安装gRPC，安装的路径就是2.编译设置中-DCMAKE_INSTALL_PREFIX所对应的路径。

至此，gRPC安装完成。

5、Qt使用gRPC

（1）Qt添加gRPC库文件（注意引用顺序，不能更改）

注意：这些导入的类需要在其他类之前导入，另外此处头文件与库文件路径本人采用了相对路径，可自行改为绝对路径

（2）Qt添加gRPC头文件

INCLUDEPATH += $$PWD/../../grpc/GRPCPACKAGE/include
 
DEPENDPATH += $$PWD/../../grpc/GRPCPACKAGE/include

（3）Qt添加proto相关.pb.h等文件

 具体proto编译相关方法，请参照我的上篇文章第5章的（1）编译proto文件的操作

windows+vs2017 C++编译gRPChttps://blog.csdn.net/weixin_44328139/article/details/136504504?spm=1001.2014.3001.5502添加.pb.h等相关文件到项目目录中

        （4）编写类方法使用proto

        略 

6、踩过的坑

        在Ubuntu Qt 中使用grpc 的使用类（即对proto中通讯进行了简单封装以供使用的类）时，仅仅包含了头文件，编译没有错误，新建类并进行实例化，即如下：

GrpcClient demoClient(grpc::CreateChannel(target_str, grpc::InsecureChannelCredentials()));

出现奇怪错误——显示各种缺少包含的库，当增加了类中首个通讯协议的发送函数的使用（即使此行代码不会被使用到，如下），也能编译通过，目前没有找到原因。

GrpcClient demoClient(grpc::CreateChannel(target_str, grpc::InsecureChannelCredentials()));
 
fun(){
    demoClient.sendDemo(1);
}
