how to use Coolprop in visual studio community 2022

[liuwei-kyushu]

Excuse me.
I am not good at programing.
Who can teach me step by step how to use Coolprop in visual studio community 2022 (visual C++ 2022)?

You'll need cmake, once you have that going, you need to make a folder called bld (or whatever you want) in the CoolProp source, and make a file called my main.cpp, with the contents perhaps like these ones: http://www.coolprop.org/coolprop/wrappers/StaticLibrary/index.html#usage, open a terminal there, and then do something like:

cmake .. -DCOOLPROP_MY_MAIN=mymain.cpp

and then open the generated project file in your VS instance.

主要方法来自于这里：

补充了一些踩坑过程。

〇、依赖
来源：http://www.coolprop.org/coolprop/wrappers/index.html#wrapper-common-prereqs

编译过程需要依赖这些东西：

git (to interface with the CoolProp repository at https://github.com/CoolProp/CoolProp)

python (to generate the header files and convert them to binary file)

CMake (platform-independent software to generate makefiles)

C++ compiler

7-zip

 

都需要加入到环境变量中，即：在命令行直接执行时，可以调用的到。比如：

On Windows, download the newest binary installer for CMake from CMake downloads. Run the installer. Check that at the command prompt you can do something like:

C:\Users\XXXX>cmake -version
cmake version 2.8.12.2


For git, your best best is the installer from http://msysgit.github.io/. Check that at the command prompt you can do something like:

C:\Users\XXXX>git --version
git version 1.9.4.msysgit.0


For 7-zip, download the installer from http://www.7-zip.org/ . Check that at the command prompt you can do something like:

C:\Users\XXXX>7z

7-Zip [64] 9.20 Copyright (c) 1999-2010 Igor Pavlov 2010-11-18

Usage: 7z <command> [<switches>...] <archive_name> [<file_names>...]

一、下载
命令 git clone https://github.com/CoolProp/CoolProp --recursive   

这个命令因为科学网的原因，可能会下载不完整，推荐使用github desktop进行下载。

二、修改错误
修改：
coolprop\dev\generate_headers.py

gitrev_to_file 函数改为以下内容。

def gitrev_to_file(root_dir):
 """
 If a git repo, use git to update the gitrevision. If not a git repo, read
 the gitrevision from the gitrevision.txt file. Otherwise, fail.
 """
 hashes['gitrevision'] = "myprop20230425"
修改：
coolprop\src\CoolProp.cpp

65行找不到引用，注释掉 gitrevision.h的引用

963行提示未定义标识符gitrevision，改为version

三、编译
32位
 
mkdir build86 && cd build86
 
cmake .. -DCOOLPROP_CSHARP_MODULE=ON -DCOOLPROP_NO_EXAMPLES=ON -DCOOLPROP_SWIG_OPTIONS="-namespace MyProp" -G "Visual Studio 15 2017"
 
cmake --build .
64位
mkdir build64 && cd build64
 
cmake .. -DCOOLPROP_CSHARP_MODULE=ON -DCOOLPROP_NO_EXAMPLES=ON -DCOOLPROP_SWIG_OPTIONS="-namespace MyProp" -G "Visual Studio 15 2017 Win64"
 
cmake --build .
编译完成后，会在build文件夹里生成 platform-independent.7z，这个压缩包里的内容是C#调用Coolprop需要的中间件。

注意上述的指令中，使用了namespace，设置为MyProp，对应生成的中间件也会跟着变化，需要配套使用。
