Prerequisite: CMake 2.8+, .NET 4.6.2+, GCC 5.0+ or Microsoft Visual C++ 2017 Community Edition
- Build Project
cd Il2Native
MSBuild Il2Native.sln /p:Configuration=Release /p:Platform="Any CPU"
or open Il2Native.sln in Visual Studio 2017 and compile it
- Build CoreLib (aka mscorlib)
cd CoreLib
MSBuild CoreLib.csproj /p:Configuration=Release /p:Platform="AnyCPU"
- Create a temporary folder to build projects/files
cd ..\..
mkdir playground
cd playground
- Generating CoreLib C++ project
..\Il2Native\Il2Native\bin\Release\Cs2Cpp.exe /release ..\Il2Native\CoreLib\CoreLib.csproj
- Compile it
cd CoreLib
build_prerequisite_vs2017_release.bat
build_vs2017_release.bat
Now you have compiled CoreLib (mscorelib)
- Compile HelloWorld.cs
cd ..
create file HelloWorld.cs
using System; class X { public static int Main (string [] args) { Console.WriteLine ("Hello, World!"); return 0; } }
..\Il2Native\Il2Native\bin\Release\Cs2Cpp.exe /release HelloWorld.cs /corelib:..\Il2Native\CoreLib\bin\Release\CoreLib.dll
cd HelloWorld
build_vs2017_release.bat
Now you have HelloWorld.exe
- Build Core Lib
Cs2Cpp.exe /release <path_to_git>\coreclr\src\mscorlib\System.Private.CoreLib.csproj
- Build any Library project, for example System.Private.Uri
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Private.Uri\src\System.Private.Uri.csproj /corelib:System.Private.CoreLib.dll /p:Configuration=netstandard2.0-Windows_NT-Release
- Compile it
First Core library
cd System_Private_CoreLib
build_prerequisite_vs2017_release.bat
build_vs2017_release.bat
Then your targeted library
cd System_Private_Uri
build_vs2017_release.bat
- Generating source code for each reference
Cs2Cpp.exe /release <path_to_git>\coreclr\src\mscorlib\System.Private.CoreLib.csproj
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Collections\src\System.Collections.csproj /p:Configuration=netstandard2.0-Windows_NT-Release
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Diagnostics.Contracts\src\System.Diagnostics.Contracts.csproj /p:Configuration=netstandard2.0-Windows_NT-Release
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Diagnostics.Tools\src\System.Diagnostics.Tools.csproj /p:Configuration=netstandard2.0-Windows_NT-Release
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Resources.ResourceManager\src\System.Resources.ResourceManager.csproj /p:Configuration=netstandard2.0-Windows_NT-Release
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Runtime.Extensions\src\System.Runtime.Extensions.csproj /p:Configuration=netstandard2.0-Windows_NT-Release /corelib:System.Private.CoreLib.dll
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Runtime.InteropServices\src\System.Runtime.InteropServices.csproj /p:Configuration=netstandard2.0-Windows_NT-Release
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Text.Encoding.Extensions\src\System.Text.Encoding.Extensions.csproj /p:Configuration=netstandard2.0-Windows_NT-Release
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Threading\src\System.Threading.csproj /p:Configuration=netstandard2.0-Windows_NT-Release
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Threading.Tasks\src\System.Threading.Tasks.csproj /p:Configuration=netstandard2.0-Windows_NT-Release
Cs2Cpp.exe /release <path_to_git>\corefx\src\System.Console\src\System.Console.csproj /p:Configuration=netstandard2.0-Windows_NT-Release /corelib:System.Private.CoreLib.dll
- Generate source code for "Hello World" executable
Cs2Cpp.exe /release helloworld.cs /ref:System.Console /corelib:System.Private.CoreLib
- Compile all projects one by one calling
cd <System.*>
build_vs2017_release.bat
- Prepare CoreRT to build, run
init-tools.cmd
build.cmd
This should generate 'AsmOffsets.cs'. Ensure it is placed into folder <path_to_git>\corert\bin\obj\Native\Windows_NT.x64.Release\Runtime\Full\
- Build Core Lib
Cs2Cpp.exe /release <path_to_git>\corert\src\System.Private.CoreLib\src\System.Private.CoreLib.csproj /p:Platform=x64
- Compile it
cd System_Private_CoreLib
build_prerequisite_vs2017_release.bat
