Can't Start on Wayland

[ggnoredo]

Hi,

I recently purchased QCAD/CAM. I have 2 computers with macOS and Arch Linux installed. I successfully installed on macOS but on Arch Linux, actually on Wayland session type it won't launch. I did see first launch screen with some configurations like metric system etc.. but after that it's just nothing happening. I'm using the latest version of qcadcam-3.24.3-pro-linux-qt5.13-x86_64.run file from mail link and

my system specs:

Kernel: 5.7.12-arch1-1
WM: sway
CPU: AMD Ryzen 5 2600 (12) @ 3.850GHz
GPU: AMD ATI Radeon RX 5600 OEM/5600 XT / 5700/5700 XT
Memory: 2302MiB / 16005MiB

Running qcad from /opt/qcadcam-3.24.3-pro-linux-qt5.13-x86_64/qcad outputs:

QCAD version 3.24.3
Warning: Could not find the Qt platform plugin "wayland" in ""
Fatal: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: linuxfb, minimal, offscreen, xcb.

./qcad: line 9: 9062 Aborted (core dumped) LD_LIBRARY_PATH="$DIR" "$binary" "$@"

QCAD has unexpectedly quit.

Please use the offscreen platform plugin for headless systems
(without a running X11 server):
./qcad -platform offscreen

In addition, you might have to override the default Qt style
to prevent the loading of a native desktop style (such as GTK):
./qcad -style plastique

QT5:

Qt 5.15.0 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 10.1.0) on "wayland"

Wayland specific env settings:

Code: Select all

export RADV_PERFTEST=aco
export QT_QPA_PLATFORM=wayland
export GDK_BACKEND=wayland
export XDG_SESSION_TYPE=wayland
export mesa_glthread=true

Can you try this with the 3.24.3.10 snapshot release, available from your download link under "Snapshots"? Thanks.

Still the very same error

[ggnoredo]

Any idea? Or I’m looking for support in wrong place?

[andrew]

You could also try to remove the Qt libraries that come with QCAD. QCAD will then link against the Qt libraries installed on your system.

Generally speaking, this is an issue of running Qt applications on Wayland. To be honest I have little experience with that. QCAD seems to work fine here on Ubuntu running Wayland, but it might be running on some compatibility layer.

I'm getting qcad launch screen for a moment but now throws completely new error

Please remove the OpenGL plugin by deleting it or moving it to a temporary folder:
plugins/libqcadgles3d.so
