为什么没有针对grpc的预编译c ++库 [英] why there is no precompiled c++ library for grpc

问题描述

我正在尝试将grpc集成到C ++项目中.但是我发现唯一的方法是下载所有源代码并自行编译.

I'm trying to integrate grpc into C++ projects. but I found the only way is download all source code and compile it by my self.

有什么方法可以获取预编译的.so/.a文件(可以链接到该文件)和grpc_cpp_plugin(适用于Linux)吗?

Is there any way to get a precompile .so/.a file which I can link against and a grpc_cpp_plugin for Linux?

或者c ++不可能这样做，为什么?

Or is it impossible for c++ to do so and why?

推荐答案

如果您正在寻找预编译的gRPC库，则应使用 vcpkg ，我做到了这一点. 只需执行以下几个步骤即可:

If you are looking for precompiled gRPC libraries you should go with vcpkg. I was also trying to cross compile gRPC, without building the library itself. With vcpkg I achieved this quite well. There are just a few steps to set this up:

1. 从GitHub中拉出vcpkg并按照说明进行设置
2. 使用" ./vcpkg install grpc "
安装grpc.
3. 将 CMakeLists.txt 中的CMAKE_TOOLCHAIN_FILE设置为vcpkg文件夹中的" vcpkg.cmake "文件
4. 在您的 CMakeLists.txt
中添加gRPC

1. Pull vcpkg from GitHub and follow the instructions to set it up
2. Install grpc with "./vcpkg install grpc"
3. Set CMAKE_TOOLCHAIN_FILE in your CMakeLists.txt to the "vcpkg.cmake"-file in your vcpkg-folder
4. Add gRPC in your CMakeLists.txt

这是我的CMakeLists.txt:

Here is my CMakeLists.txt:

cmake_minimum_required(VERSION 3.1)

if(DEFINED ENV{VCPKG_ROOT})
    set(CMAKE_TOOLCHAIN_FILE $ENV{VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake)
else()
    set(CMAKE_TOOLCHAIN_FILE "/path_to_vcpkg/scripts/buildsystems/vcpkg.cmake")
endif()

project(Foo)

find_package(gRPC CONFIG REQUIRED)

...

add_executable(${PROJECT_NAME} ${Bar})

target_link_libraries(${PROJECT_NAME} PRIVATE gRPC::gpr gRPC::grpc gRPC::grpc++ gRPC::grpc_cronet)

在文件夹 path_to_vcpkg/packages/grpc_x64-PLATFORM/tools/grpc 中，您会找到适用于您平台的所有预编译grpc插件(也 grpc_cpp_plugin ).

In the Folder path_to_vcpkg/packages/grpc_x64-PLATFORM/tools/grpc you will find all the precompiled grpc-plugins for your platform (also grpc_cpp_plugin).

优点:

• 易于设置
• vcpkg可用于所有常见平台
• 如果不再需要软件包，则只​​需删除" path_to_vcpkg/packages "中的文件夹
• 包括您需要的所有gRPC工具

• easy to set up
• vcpkg is available for all common plattforms
• if a package isn't needed anymore you can just delete the folder in "path_to_vcpkg/packages"
• includes all the gRPC tools you need

缺点:

• 安装某些软件包后，" path_to_vcpkg/packages "文件夹变得很大

• the "path_to_vcpkg/packages" folder gets quite big after some packages installed
