    Does is it possible to self compiling the generated code from il2cpp output folder?.

    I have tried to compile with Visual Studio 2017 15.7.3 with adding all of the *.cpp, adding "C:\Program Files\Unity\Editor\Data\il2cpp\libil2cpp" as additional include dir.

    And after some tinkeringalso adding the following into my preprocessor :
    Code (csharp):
    1.  
    2. NDEBUG
    3. _WINDOWS
    4. _MSC_VER
    5. _ALLOW_COMPILER_AND_STL_VERSION_MISMATCH
    6. NET_4_0
    7.  
    But looks like there is no il2cpp.lib, hence the final linking is not possible because of no il2cpp.lib included in the unity default installation, and also compiling from libil2cpp folder is too many error from the project file.

    The reason for these are i wanted to add custom DRM into my il2cpp compiled windows games, should i use UnityLinker ?. If so how to do it?, what is the steps.

    Another feature request would be, unity should be automatically generating .visual studio project/solution file for the self compiled il2cpp output.

    We added this feature in 2018.2. I highly suggest you checkout the beta!

    The key to building IL2CPP generated code is to invoke il2cpp.exe to do it for you:

    Code (csharp):
    1. "<UNITY_INSTALL_DIR>\Editor\Data\IL2CPP\build\il2cpp.exe" --libil2cpp-static --compile-cpp -architecture=x64 -configuration=Release -platform=WindowsDesktop -outputpath="<OUTPUT_PATH>" --data-folder="<PATH_TO_GENERATED_IL2CPP_DATA_FOLDER>" -cachedirectory="<directory_for_cached_object_file>" -generatedcppdir="<directory_with_generated_source_code>" --additional-defines=UNITY_WIN=1 --additional-defines=UNITY_STANDALONE_WIN=1 --additional-defines=PLATFORM_WIN=1 --additional-defines=PLATFORM_STANDALONE_WIN=1 -dotnetprofile=unityjit -verbose --map-file-parser="<UNITY_INSTALL_DIR>\Editor\Data\IL2CPP\MapFileParser\MapFileParser.exe"
    Now, the important bit is the dotnetprofile argument, and it's important to match it to whatever you have specified in player settings (otherwise all kinds of stuff will explode):

    .NET 2.0 Subset: "legacyunity"
    .NET 2.0: "net20"
    .NET 4.x: "unityjit"
    .NET Standard 2.0: "unityaot"

    I believe it defaults it to compiling it into an executable if you don't provide an extension to your output path. And executable needs a WinMain to be compiled. Try changing the output path parameter to "C:\Users\nameless\Documents\Works\Projects\Unity\DarkRift2\Built\Test.dll"

    WOW, cool, working fine now, thanks.

    There are few caveats for compiling MapFileParser on windows :
    Change all occurrences of
    Code (csharp):
    1.  
    2. #include "UnityPrefix.h"
    3.  
    into :
    Code (csharp):
    1.  
    2. #include "../../UnityPrefix.h"
    3.  
    Also comment out these following line on UnityPrefix.h :
    Code (csharp):
    1.  
    2. // This has to be included before defining platform macros.
    3. //#include "Configuration/PrefixConfigure.h"
    4.  
    5. #ifdef _DEBUG
    6. #if defined(ENABLE_UNIT_TESTS)
    7. #undef ENABLE_UNIT_TESTS
    8. #endif
    9. #define ENABLE_UNIT_TESTS 1
    10. #endif
    11.  
    12. //#include "Runtime/Logging/LogAssert.h"
    13.

    Hmm, it shouldn't compile map file parser if it finds it in the place you specified on the command line.

    On mine, the "C:\Program Files\Unity 2018.2.0b8\Editor\Data\IL2CPP\MapFileParser\MapFileParser.exe" doesn't exist or not compiled yet o_O.

    About the il2cpp output, is there any more documentation on how the Unity Player loaded the compiled gameassembly.dll?. I meant in which function does the Unity Player loaded the Bulk_Assembly-CSharp-firstpass_0.cpp & Bulk_Assembly-CSharp_0.cpp ?.

    I am trying to make a tutorials for virtualizing the most important function in generated il2cpp output. Here is the function that i was tried :


    but no luck, the dll seems doesn't load anymore. What i have meant is sort of entry point of functions to load the compiled game's script.

    Looks like MapFileParser is in a different directory, my bad. It's in "Editor\Data\Tools\MapFileParser\MapFileParser.exe".

    I don't really understand your question. On Windows, Unity uses LoadLibrary API to load the native binary, and then uses GetProcAddress to get access to IL2CPP API (I highly discourage calling those API functions yourself, though. But if you want to look at the API, look for il2cpp-api.cpp).

    Is it still working @Tautvydas-Zilys ? Can't find any docs on the topic, there's no "_BackUpThisFolder_ButDontShipItWithYourGame\il2cppOutput\Data" folder only "_BackUpThisFolder_ButDontShipItWithYourGame\il2cppOutput\lumpedcpp"

    Pointed to "Build\ProjectName_Data\il2cpp_data" instead and it built fine but it created 4 files: .dll, .lib, .pdb, .exp. The created GameAssembly.dll is very small and game crashes on start.

    Edit seems like I had one path wrong, now I get this error:
