Program Wrapper For Windows Skin Is AOnline or via npm.Wineskin is a tool to run Windows programs but only for Mac OS X. NET.TypeScript is a strongly typed programming language which builds on JavaScript giving you better tooling at any scale. It is important to understand that the main utility of this advanced approach is in the ability to call the same C/C++ code on both platforms from. NET code to call functions that are implemented in a C/C++ DLL (Windows) or dylib (macOS).PrerequisitesThis guide does not presume you are a C/C++ or. NET code required to call into our library from a RhinoCommon plugin on both Windows and Mac. After that, we will examine the wrapping. HIPAA ready remote desktop management software to assist Windows, Mac and.First, we will build a simple C/C++ library that adds two numbers together. It is free to use and currently works on OS X 10.6 Snow Leopard, OS X 10.7 Lion, OS X 10.8 Mountain Lion, OS X 10.9 Mavericks and OS X 10.10 Yosemite.RDPWrap is a remote desktop wrapper application that enables remote desktop.If you are not there yet, see both Installing Tools (Windows) and Installing Tools (Mac). (On Windows, it is possible to use Rhino 6, but you will have to change the RhinoCommon references).It is presumed you already have all the necessary tools installed and are ready to go. SampleNativeLibrary builds against the RhinoWIP (on Windows) and Rhino 5 for Mac (on macOS). Please clone or download this repository. This is an advanced guide that said, the intent of this guide is to illustrate basic considerations of wrapping a C/C++ library and the logistical issues calling it from a RhinoCommon plugin on both Windows and Mac.We will be analyzing a sample solution called SampleNativeLibrary.We’ll start on Windows, but it really doesn’t matter if you start on a macOS, nearly everything that follows applies on each platform… Windows SampleLibraryLet’s begin by taking a look at an absurdly simple C/C++ “library” - SampleLibrary - that does one thing: add two numbers together. To keep things compatible with the Apple macOS, and because the IJW (it just works) technology sometimes does not, we suggest the use of PInvoke. A notorious one is based on the compilation of the C++ library with the C++/CLI compiler. NET binding to a C# library exist. There is nothing fancy going on here at all much of the code is not even relevant to this guide.Open the SampleLibrary.cpp file and take a look. The SampleLibrary (.vcxproj) is just a boilerplate C++ project (created using the regular Shared MFC C++ project wizard) that was created by Visual Studio. Expand the SampleLibrary C++ project… In the Solution Explorer, you will notice there are three projects…two C# (.csproj) projects and one C++ project. Take note of the SAMPLELIBRARY_C_FUNCTION decoration above the implementation…we will talk about that in a moment. Add takes a native int and a native double, and returns the sum of the inputs as a native double. The only important section to pay attention to is: SAMPLELIBRARY_C_FUNCTION…even if you are not a C/C++ programmer, this C function should be clear to you. The reason they are different on each platform is that Dynamic Link Libraries (DLLs) are implemented differently in Windows and macOS - each platform has a unique way of telling the linker what to do with the library. The code in these #defines are basically telling the linker to export functions in a specific way. The first thing to note is that there are two well #defined sections to this header: one that relates to Windows ( #if defined (_WIN32)) and one that relates to Mac ( #if defined(_APPLE_)). By providing this decoration, we are doing the. Without this decoration, these functions would not be available outside the the assembly (.dll or. By decorating with this macro, the linker adds information to the DLL that makes these functions public. This is the decoration that tells the linker to make the function available to outside callers. More importantly…Take a look at the function declaration at the bottom of the file: SAMPLELIBRARY_C_FUNCTION…is decorated with the same SAMPLELIBRARY_C_FUNCTION. In the Project Navigator, notice that this project is referencing the exact same source code as its Windows counterpart… (Unlike Visual Studio on Windows, on macOS, we cannot do all of our development in a single IDE, but we have to build our native C/C++ SampleLibrary using the native Apple Tools - Xcode and xcodebuild). Launch Xcode and open SampleLibrary.xcodeproj. Ok, now that we know roughly what is in the native SampleLibrary on Windows, let’s take a look at it on macOS… SampleLibrary should build without errors as the native SampleLibrary.dll in the project /bin folder. Do a “sanity check” and Build SampleLibrary to make sure that all your tools are working as expected. On each platform, we are using the exact same wrapping source code, just using cloned. NET project that calls into the SampleLibrary. NET portion of our wrapping code… SampleNativeLibrarySampleNativeLibrary is the. On macOS, we are actually going to use command line xcodebuild from Visual Studio for Mac to build our native library, but we’ll talk about that below.Now that we have examined the simple native SampleLibrary, let’s turn our attention to the. Build SampleLibrary using Xcode to make sure that it builds successfully. For all intents and purposes, SampleLibrary does exactly the same thing on macOS that it does on Windows and the source is the same. Verify that SampleLibrary.dll is present in your /bin folder. If you have not done so already, build SampleLibrary. If you have not done so already, open the SampleNativeLibrary.sln in Visual Studio. (For more information on this cross-platform strategy, see the Your First Plugin (Cross-Platform) guide).Let’s take a look at SampleNativeLibrary on Windows using Visual Studio first… Windows Office for mac osYou will be prompted to enter two numbers. Load the SampleRhino.rhp in Rhino and run the SampleRhinoCommand. Before we do anything, let’s build and test the plugin. Make sure that SampleRhino.Win is set as the Startup Project and expand it so you can see the source files… Let’s go through this class line-by-line. Open UnsafeNativeMethods.cs. The Add(first, second) method is being called on the UnsafeNativeMethods class. After prompting the user to enter two numbers, we see the following code var result = RhinoMath.UnsetValue Result = UnsafeNativeMethods.Add(first, second) Let’s take a look at how the Add function is being called.Open SampleRhinoCommand.cs and find the RunCommand method. The “additional” calculation for this command was all performed in the native C/C++ SampleLibrary.dll. This is the point at which the link between the managed. Dylib - see below).The UnsafeNativeMethods class itself contains a single function… internal static extern double Add(int a, double b) The Add function is decorated with an Attribute: …this important bit of metadata tells the runtime to look in the native library and call the associated function with a specific language (C) calling convention when the Add method is called from. Dll.config file is used to point to a. On Windows, it is necessary to explicitly state the name of the native dll being called (on macOS, a. What happens? 2 + 2 no longer equals 4. No errors or warnings, right? Now run the plugin and test the SampleRhinoCommand with this change. To illustrate this point, let’s change the code and see what happens…In UnsafeNativeMethods change the function declaration of Add to accept doubles (instead of ints) as the first argument… internal static extern double Add(double a, double b) Since we are bridging the world of managed and unmanaged code, we need to be very careful about the types of variables we are using. In Using methodgen, we will discuss a way of generating these function signatures using a utility program we wrote to maintain RhinoCommon. Managing these correspondences is challenging with all but the most trivial libraries. NET exactly matches the function declaration in the header file made in the unmanaged code (in this case, in SampleLibraryInclude.h). You must ensure that the function in. Change the type of argument a back to an int, rather than a double and save the file. The compiler did not detect the error we introduced. If you have not done so already, open the SampleNativeLibrary.sln in Visual Studio for Mac.
