How to setup D with SFML? (using bindbc-sfml)
How do I set up a D and SFML project using the `bindbc-sfml` package? I tried following the instructions, it builds successfully, but fails to load the SFML library at runtime. In particular, `loadSFML, loadSFMLGraphics, loadSFMLXXX` fails. Here is [link](https://github.com/rillki/d-sfml-project-template) to the repo. I plan to create another how-to video, but I cannot find what's causing it to fail. Do you have any ideas?

Not without error messages. The first thing you should do is use the error API in bindbc.loader to print them out. That should tell you what the problem is.

That should tell you what the problem is. I installed it on my Linux system without using a loader and with static SFML. I just used apt-get and dub. I did the following in order: 1. sudo apt-get install libsfml-dev libcsfml-dev 2. dub init dsfml bindbc-sfml 3. cd dsfml 4. edit dub.json and add: ```java "libs": [ "csfml-audio", "csfml-graphics" ], "subConfigurations": { "bindbc-sfml": "staticBC" }, "versions": [ "SFML_Audio", "SFML_Graphics" ], ``` 5. dub **app.d** ```d import bindbc.sfml; void main() { sfContextSettings* settings; sfEvent event; auto window = sfRenderWindow_create( sfVideoMode(750, 500), "Japanese Flag", sfWindowStyle.sfDefaultStyle, settings ); auto flag = sfCircleShape_create(); flag.sfCircleShape_setRadius(150); flag.sfCircleShape_setPosition(sfVector2f(225, 100)); flag.sfCircleShape_setFillColor(sfRed); while(window.sfRenderWindow_isOpen()) { while(window.sfRenderWindow_pollEvent(&event)) { if(event.type == sfEventType.sfEvtClosed) { window.sfRenderWindow_close(); } } window.sfRenderWindow_clear(sfWhite); window.sfRenderWindow_drawCircleShape(flag, null); window.sfRenderWindow_display(); } } ``` SDB@79

Here are the errors that occur on Windows: ``` csfml-system.dll, The specified module could not be found. csfml-audio.dll, The specified module could not be found. csfml-audio-2.dll, The specified module could not be found. csfml-audio-2.0.dll, The specified module could not be found. ``` Why can't it find these libraries? I tell where to look for them: ```D version(Windows) { import bindbc.loader; setCustomLoaderSearchPath("libs"); // tried using absolute path as well } ``` That is strange...

I've tried your project out two ways, one that succeeds and one that fails. I'm guessing you've put your 'libs' directory is 'bin/libs'. Am I right? If so, then the following should help you. When dub runs the exectuable, it sets the current working directory to the project's root directory by default. `setCustomLoaderPath` passes whatever you give it directly to the system API unmodified. You've passed a relative path. By default, the system API associates relative paths with the current working directory. So given a project root directory of `$ROOT`, and your executable in `$ROOT/bin`, the system is looking for the libraries in `$ROOT/libs` and *not* in `$ROOT/bin/libs`. If the libs are in the former, everything loads. If they're in the latter, then it's going to fail. If you cd into `bin` and run the executable manually, then libs in `$ROOT/bin/libs` will load, as your current working directory is `bin`. The quick fix for this is to add `"workingDirectory" : "bin"` to your dub.json. Then your relative paths will be relative to `$ROOT/bin/`. Bear in mind that when using relative paths like this, any file reading is bound to break if someone runs your executable from outside its directory. You can test this by going into `$ROOT` from the command line and executing `bin/d-sfml-project-template`. Then you'll be doing the same thing dub does, i.e., your working directory will be `$ROOT`. The way to guarantee your relative paths are always relative to the executable are to either set the current working directory to the executable's path, or to prepend all relative paths with the executable's path before handing them off to the system. There are two ways you can get the full path to the executable in Phobos/DRuntime: via `std.file.thisExePath`, or `core.runtime.Runtime.args[0]`. (The former is failing to compile for me on Windows right now due to a bug in the Phobos Win32 API bindings. I'll look into it.) Strip the file name from the returned path, then you can use it as required.

It did not work. --- Actually, it is quite strange that it fails to load the [CSFML](https://www.sfml-dev.org/download/csfml/) library dlls in `libs/` (I download CSFML2.5) since that is what I do with [GLFW/OpenGL](https://github.com/rillki/d-glfw-opengl-project-template) example as well for Windows 10. **Even this fails: `loadSFMLGraphics("libs/csfml-graphics.dll")`** I have the following structure: ``` - bin/ - libs/ - source/ - dub.json - dub.selections.json ``` My `dub.json`: ```Json { "authors": [ "rillki" ], "copyright": "Copyright © 2023, rillki", "dependencies": { "bindbc-sfml": "~>1.0.2" }, "description": "D/SFML project template", "license": "BSL", "name": "d-sfml-project-template", "targetPath": "bin", "versions": [ "SFML_Audio", "SFML_Graphics", "SFML_Network", "SFML_System", "SFML_Window", "SFML_250" ] } ``` My `source/app.d`: ```d module app; import std.stdio: writeln; import bindbc.sfml; void main() { version(Windows) { import bindbc.loader; setCustomLoaderSearchPath("libs"); } // attempt at loading sfml if(!loadSFML()) { writeln("Failed to load SFML library!"); return; } // window dimensions enum width = 720; enum height = 480; enum title = "D/SFML project"; // create window auto window = sfWindow_create(sfVideoMode(width, height), title.toStringz, sfWindowStyle.sfDefaultStyle, null); scope(exit) { sfWindow_destroy(window); } while(sfWindow_isOpen(window)) { // process events sfEvent event; while(sfWindow_pollEvent(window, &event)) { if(event.type == sfEventType.sfEvtClosed) { sfWindow_close(window); } } // ... } } ``` I will try to make it work... Meanwhile, if someones spots what I am doing wrong, please reply to this post.

I have to ask this since nothing else has worked and the dll's on the site don't depend on a MSVC dll: What are you compiling your program as? 32bit/64bit x86? ARM? Which DLL's are you downloading? 32bit, 64bit?

ARM? Which DLL's are you downloading? 32bit, 64bit? I uses the default settings. DUB should compile my project as 64bit on Windows 10. The bindings I downloaded are also 64bit. The links mentioned in my previous post is what I use.

Since this library is a component of the Microsoft C Runtime (CRT) library, you may need to install this library. To install the CRT library, follow these steps: * Download and install the latest version of Microsoft Visual Studio. * In the Visual Studio installer, install the "C++ Universal CRT" component under "Workloads > Desktop development with C++". * Restart the build and check if the error is resolved. **Source:** https://stackoverflow.com/questions/44763817/link-fatal-error-lnk1104-cannot-open-file-ucrt-lib SDB@79

That worked! Now I have a working example. Though it's strange that it does not work with shared libs.

Good luck, I'm really happy for you... Ki Rill, wait a minute! Actually, i've been very happy for the D community. Because I really appreciate what you've done. You are an idealistic person and please stay that way. We can do more things. SDB@79
