今天倒腾windows下面grpc编译以及在qt下面如何简单实用

1.grpc的编译工具准备

根据官网说明，安装下面的相关工具。

Windows

To prepare for cmake + Microsoft Visual C++ compiler build

• Install Visual Studio 2015 or 2017 (Visual C++ compiler will be used).
• Install Git.
• Install CMake.
• Install Active State Perl (choco install activeperl) - required by boringssl
• Install Go (choco install golang) - required by boringssl
• Install yasm and add it to PATH (choco install yasm) - required by boringssl
• (Optional) Install Ninja (choco install ninja)

2.clone 代码库

Windows
@rem You can also do just "git clone --recursive -b THE_BRANCH_YOU_WANT https://github.com/grpc/grpc"
git clone --recursive -b https://github.com/grpc/grpc.git
cd grpc
@rem To update submodules at later time, run "git submodule update --init"

3.使用cmake编译

cmake: Windows, Using Visual Studio 2015 or 2017 (can only build with OPENSSL_NO_ASM).
When using the "Visual Studio" generator, cmake will generate a solution (grpc.sln) that contains a VS project for every target defined in CMakeLists.txt (+ few extra convenience projects added automatically by cmake). After opening the solution with Visual Studio you will be able to browse and build the code.

@rem Run from grpc directory after cloning the repo with --recursive or updating submodules.
md .build
cd .build
cmake .. -G "Visual Studio 14 2015" -DCMAKE_BUILD_TYPE=Release
cmake --build .

由于需要debug版本，只需要将cmake的倒数第二步修改成即可。

cmake .. -G "Visual Studio 14 2015" -DCMAKE_BUILD_TYPE=Debug

编译过程很顺利，没有什么错误提示。

4.在qt中使用生成的debug以及release库

下面是自己一步一步尝试出来的使用的pro文件，在当前目录下面建立了staticlib文件夹以及子文件夹debug与release，分别放置debug以及release库。
自己没有找到具体include 的lib指导，自己慢慢摸索出来的，有蛮多的坑的。一些简单的说明

INCLUDEPATH += ../include 是拷贝grpc/include下面的所有的头文件

其他的包含库，只需要按照下面，拷贝生成目录下面对应的debug以及release文件即可

DEFINES += _WIN32_WINNT=0x600 是grpc需要的define

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = greeter
TEMPLATE = app

INCLUDEPATH += ../include

# The following define makes your compiler emit warnings if you use
# any feature of Qt which has been marked as deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0
