Hello Vasi. Yes, I know but... I already found a solution and it works, so I will continue the fight (even that I admit that Wayland is not wow)!
See screenshot: https://github.com/fredvs/wayland-pascal/assets/3421249/e8053dbc-a7e7-4c8a-a206-bbd7ded16a84 The trick was to create a library-for-work with the declared functions and use that library for linking. That library is only need for linking, users dont need it. So now I think I get great keys. Hum, yes, sorry but once again ChatGPT helped me a lot. Here his answer: -------------------------------------- If the `wl_display_get_registry` and `wl_registry_add_listener` functions are inlined in the C/C++ headers and you cannot directly access them from Pascal due to the inlining, you may need to use a workaround. One approach is to create C/C++ wrapper functions that encapsulate the inlined Wayland functions and then call those wrapper functions from your Pascal code. Here's an example of how you can create such wrappers: 1. Create a C/C++ file, e.g., `wayland_wrapper.c`, and define wrapper functions for the inlined functions: ```c // wayland_wrapper.c #include <wayland-client.h> // Wrapper for wl_display_get_registry struct wl_registry* my_wl_display_get_registry(struct wl_display* display) { return wl_display_get_registry(display); } // Wrapper for wl_registry_add_listener int my_wl_registry_add_listener(struct wl_registry* registry, const struct wl_registry_listener* listener, void* data) { return wl_registry_add_listener(registry, listener, data); } ``` 2. Compile `wayland_wrapper.c` into a shared library (e.g., `libwayland_wrapper.so`): ```bash gcc -fPIC -shared -o libwayland_wrapper.so wayland_wrapper.c -lwayland-client ``` 3. In your Pascal code, use the `external` keyword to declare the wrapper functions: ```pascal function my_wl_display_get_registry(display: pwl_display): pwl_registry; cdecl; external 'libwayland_wrapper'; function my_wl_registry_add_listener(registry: pwl_registry; listener: Pwl_registry_listener; data: pointer): cint; cdecl; external 'libwayland_wrapper'; ``` 4. Use these wrapper functions in your Pascal code as needed. By creating C/C++ wrappers, you can access the inlined Wayland functions indirectly from your Pascal code. Make sure to link your Pascal program with the `libwayland_wrapper.so` shared library when building your Pascal project. This approach allows you to work around the issue of inlined functions in the Wayland headers and use them in your Pascal code effectively. ________________________________ De : vasi vasi <funl...@gmail.com> Envoyé : vendredi 22 septembre 2023 19:10 À : General list for MSEide+MSEgui <mseide-msegui-talk@lists.sourceforge.net> Objet : Re: [MSEide-MSEgui-talk] MSEgui and Wayland. Fred, let the Wayland team to solve the problems they created in forcing the move from X-Window with a half baked solution. We (me and my family) use X server because is the only one that correctly manages the Wacom tablet. For now we don't care about Wayland is not useful for us and is really their problem. Wait for when things are usable. Not worth the effort at the expense of your health. On Fri, Sep 22, 2023 at 6:40 PM Fred vS <fi...@hotmail.com<mailto:fi...@hotmail.com>> wrote: Hello everybody. I am already blocked because some methods in wayland-client.so are inlined and not accessible for fpc. I have asked it to the maintainer of the Wayland book with the demos: https://github.com/bugaevc/writing-wayland-clients/issues/2 But I dont understand his solution. Do you have a idea what should be done to access those methods?

Hello everybody. For the fun, I started a new Github project: https://github.com/fredvs/wayland-pascal It takes inspiration of the demos from: https://bugaevc.gitbooks.io/writing-wayland-clients/content/black-square/first-steps.html (Yes, I confess, I was helped by ChatGPT for the translation of the C demos to Pascal.) It uses the excellent fpc-wayland Bindings Generator for freepascal from Andrews Haines. https://github.com/andrewd207/fpc-wayland The goal is to discover step by step, with code, how to make Wayland work with fpc. And maybe one day adapt this for msegui. The first step is a Pascal program that connect to a Wayland Client (of course you need a Wayland session): https://github.com/fredvs/wayland-pascal/assets/3421249/1a29cd1b-5af0-4fd4-9b70-d87a9a4e9148 Fre;D _______________________________________________ mseide-msegui-talk mailing list mseide-msegui-talk@lists.sourceforge.net<mailto:mseide-msegui-talk@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/mseide-msegui-talk -- Vasi
