Next steps now should be

- macosx
- android
- maybe "gtk backend" - one which is more tightly bound to gtk
- ditto for QT

Volunteers needed Smile

You forgot to add the Wayland display server to your list Wink

The drawing part will be probably quite similar to framebuffer, so it shouldn't be very difficult.

I already tried to compile wayland and get it running on my Arch Linux with mixed results - the server runs, the clients don't Confused

But as soon as I get it to work, I promise to volunteer Wink

As I promised, I'm here to volunteer Very Happy

. I've finally compiled everything necessary to run wayland as well as the example compositor and client applications. I also tried to incorporate U++ into the examples - and here comes the first problem Smile

I started with the simplest available example (just about 200 lines of code Smile

) and tried to put in some U++ drawing code. But as soon as I add the Draw package into the project, I started getting these runtime errors:

Quote:

unknown object (138760168), message create_buffer(nhiiuo)
unknown object (2049), message attach(oii)
wl_display@1: error 1: invalid arguments for wl_shm@6.create_buffer
disconnect from client 0x9637030
Aborted

This happens as soon as I link Draw to the executable, even when using no code from the package (not even include Draw/Draw.h). Based on this behavior I figured it is related to INITBLOCKs and tracked the problem down to call of sInitFonts() in Draw/Font.cpp:49. I have no idea how can it influence the wayland code (any hints?), but as soon as I commented it out, the problem disappeared. It also works fine when explicitly called from CONSOLE_APP_MAIN after the wayland display is initialized.

So far I have just very basic stuff, drawing an Image on the screen. In the next days, I'll begin to incorporate this into the rainbow framework. As I already said, it should be pretty straight forward. I will use this thread to keep you informed about the progress. Also I can post the package if anyone is interested (and has libwayland-* libraries ready)...

Best regards,
Honza
