'make' is not recognized as an internal or external command, operable program or batch file.

[JAMES Bruce]

Have tried to run the basic example of the C# code on my PC but when I try to use the following bit of code:

make build SOURCE=examples/dotnet/SimpleProgram.cs

 I get the following error:

'make' is not recognized as an internal or external command,
operable program or batch file.

I currently have or tools downloaded in the following path: 

C:\Users\LSLla\OneDrive\Documents\Computation\or-tools_VisualStudio2019

Here is my input in the .csproj file:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <LangVersion>7.3</LangVersion>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <EnableDefaultItems>false</EnableDefaultItems>
    <!-- see https://github.com/dotnet/docs/issues/12237 -->
    <RollForward>LatestMajor</RollForward>
    <RestoreSources>../../../temp_dotnet/packages;$(RestoreSources);https://api.nuget.org/v3/index.json</RestoreSources>
    <AssemblyName>Google.OrTools.BasicExample</AssemblyName>
    <IsPackable>true</IsPackable>
  </PropertyGroup>

  <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
    <DebugType>full</DebugType>
    <Optimize>true</Optimize>
    <GenerateTailCalls>true</GenerateTailCalls>
  </PropertyGroup>

  <ItemGroup>
    <Compile Include="BasicExample.cs" />
    <PackageReference Include="Google.OrTools" Version="9.1.*" />
  </ItemGroup>
</Project>

within the .cs file, I am trying to import the following libraries:

using System;

using Google.OrTools.LinearSolver;

Any ideas?

Thanks

I have tried this and got the following error:

the cl command was not found in your PATH
exit 127
make: *** [Makefile:271: cc] Error 127

same doc, you need to use the command line supplied with visual studio

sorry, I have noticed that the link you sent was for C++ - is this still valid for C# working with dotnet framework? 

at the moment I am using vscode - will I need to be working with full visual studio to get this working?

[Laurent Perron]

The library is in C++. wrapped in C#.
