SIGFPE crash in virtualbox about wlc HOT 12 CLOSED

Is this llvmpipe? The mesa's old swrast does not work at least, however llvmpipe worked here at least under X11.

from wlc.

Yes, it is llvm pipe..

from wlc.

Maybe you could set WAYLAND_DISPLAY variable to something before running compositor. It will skip the SIGFPE setup (see: https://github.com/Cloudef/wlc/blob/master/src/wlc.c#L429-L434). However if this works, it most likely just hides bug in swrast.

There also seems to be software rendering related bug with latest mesa regarding weston https://bugs.freedesktop.org/show_bug.cgi?id=86701

from wlc.

Thanks! Works fine in VMWare.. Maybe go with that instead of VirtualBox (better support for hardware rendering..)

from wlc.

Oh it does not really work as I hoped.. I have hardware rendering working in VMWare. X11 works just fine. I can run wlc/example and weston under X11 in a window. Without X11 I can not run wlc/example or weston from console so I guess maybe the problem is in wayland or vmware.. weston says "failed to create display: no such file or directory".. According to wlc log, wlc tries to open Xwayland rather than using drm..

from wlc.

Ah! Progress. Got weston running by using "weston --backend=drm-backend.so" so it should be possible to run wlc as well, right?

from wlc.

Xwayland is not related to rendering. It's thing that provides you X11 inside Wayland. wlc will use drm when run from TTY. Can you show the full log for wlc.

from wlc.

Got this log:

from wlc.

It seems like it's running OK, apart that it does not find any outputs and thus does not open any GLES2 context either.

from wlc.

What was the state of this issue. We got vmware to work at least partially, how was virtualbox?

from wlc.

Hardware rendering seem to be working somewhat on VirtualBox using Lubuntu 15. Weston does not run and wlc/example runs with this log. Screen is all black..

It seems virtualbox does not implement KMS I guess? Weston won't run without it, and wlc will fallback to headless mode (Which may not be what people want actually)
