Question

我有几个用C / C ++编写的遗留组件，并希望将它们包装到Nuget包中，并使用C＃代码中的这个包。在nuget包中实际包装C ++代码的最佳方法是什么？我查看了CoApp解决方案，但现在似乎不受支持（稳定版离线）。

Answer 1

我可以回答你如何将 c++ 打包为 Visual Studio 2017/2019 的 nuget 包。

这是我以前在visual studio中将zlib C++库打包为nuget包的方法。我广泛使用 Visual Studio 中内置的 T4 模板来生成我们需要的文件。

这假设您希望将 x86/release/debug 和 x64/release/debug 打包在同一个包中。您需要构建所有目标，然后构建我们在此处创建的新项目以生成 nuget 包。

当你在你自己的代码中包含生成的 nuget 包时，它会自动使用包含和 lib，它的零配置。您需要更改这些部分道具和目标文件以匹配您的配置以实现这一点。

由于大多数 nuget 打包说明都涵盖 c# 或 C++ Unix，因此这些信息很难掌握和整理。我必须找出秘诀。

在 Visual Studio 中为基本的 c# 应用程序创建新项目。
您需要创建并添加以下文件。
添加构建事件
修补对 nuget.exe 之类的外部引用。

将其放入名为：thirdparty.ttinc

<#@ assembly name="System" 
#><#@ assembly name="System.Core" 
#><#@ import namespace="System.IO" 
#><#@ import namespace="System.Linq" 
#><#@ import namespace="System.Text" 
#><#@ import namespace="System.Configuration" 
#><#@ import namespace="System.Collections.Generic" 
#><#
    string DirRoot      = @"c:\work\thirdparty\";       // Git source code package installed at.
    string NugetPrefix  = "thirdparty";         // base name for 3rd party packages.
#>

将其放入名为：_NugetVersionInclude.ttinc

<#@ include file= "thirdparty.ttinc" #><#
    // Configuration
    // increment this number for each internal release  

    string NugetInternalVersion      = @"1.0.2";                // Internal version number.

    // configured once for each new thirdparty set of code

    string NugetName                 = @"zlib";                 // Nuget name for this package.
    string NugetExternalVersion      = @"1_2_11";               // External version number as used by the original author.

    // you probably dont need to change below.

    string NugetShortname            = NugetPrefix + "-" + NugetName;   
    string NugetRootname             = NugetShortname + "_" + NugetExternalVersion; 
    string NugetFullname             = NugetRootname + "." + NugetInternalVersion;
    string NugetDescription          = NugetPrefix + " " + NugetName + " " + NugetExternalVersion;  
    string NugetOutDir               = "nuget\\";

    string DirSolution = Environment.GetEnvironmentVariable("SOLUTIONDIR");

将此添加到 PreBuildEvent

echo on
start NuGetPackagePack.bat 
exit

将此添加到 PostBuildEvent

echo on
start _UpdateTemplate.bat . "thirdparty-zlib_nuspec.tt" "thirdparty-xlw_nuspec.nuspec"

start _UpdateTemplate.bat . "thirdparty-zlib_props.tt" "thirdparty-xlw_props.props"

start _UpdateTemplate.bat . "thirdparty-zlib_targets.tt" "thirdparty-xlw_targets.targets"

start _UpdateTemplate.bat . "NugetPackagePack.tt" "NugetPackagePack.bat"

start _UpdateTemplate.bat . "NugetPackagePush.tt" "NugetPackagePush.bat"

exit 0

将其放入名为：_UpdateTemplate.bat

echo on
del %3
set SOLUTIONDIR=%1
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\TextTransform.exe" -out %3 %2

rem uncomment pause to see output to help debug 
rem pause

exit 0

将其放入名为：thirdparty-zlib_nuspec.tt

调用那些 c lib 函数可能会在其他地方得到解答。寻找 pinvoke 作为起点。
