If the Wayland issue is unfixable, here's a custom desktop file which you can place at ~/.local/share/applications/openscad.desktop:

[Desktop Entry]
Type=Application
Version=1.0
Name=OpenSCAD (XWayland)
Comment=The Programmers Solid 3D CAD Modeller (XWayland)
Icon=openscad
Exec=env QT_QPA_PLATFORM=xcb openscad %f
StartupWMClass=org.openscad.openscad
MimeType=application/x-openscad;
Categories=Graphics;3DGraphics;Engineering;
Keywords=3d;solid;geometry;csg;model;stl;
Actions=Wayland;

[Desktop Action Wayland]
Name=Default start maybe with Wayland
Exec=openscad %f
Comment=The Programmers Solid 3D CAD Modeller (default start)

It forces OpenSCAD to XWayland on a pure Wayland system (QT_QPA_PLATFORM=wayland) by default. You can right click and choose the default startup any time.
Don't forget update-desktop-database to apply or reboot.

3D view doesn't show up on Plasma+Wayland+Nvidia.

I already tried moving away from EGL: -DENABLE_EGL=OFF -DUSE_GLEW=ON. But only forced XWayland works for me: QT_QPA_PLATFORM=xcb openscad

now that lib3mf 2.4.1-2 has been released, openscad builds without any workarounds

@frysztak

I looked into this, apparently the root cause is: lib3mf 2.4.1-1 ships a broken pkg-config file.

On Arch, the installed file: /usr/lib/pkgconfig/lib3mf.pc

contains build-tree paths instead of install-tree paths:

 libdir=${exec_prefix}//build/lib3mf/src/lib
 includedir=${prefix}//build/lib3mf/src/include/lib3mf

Those directories do not exist on the system after installation.

The Arch lib3mf package needs to regenerate/install lib3mf.pc with:

includedir=/usr/include/lib3mf
libdir=/usr/lib

My workaround without downgrading 3MF is as follows:

sudo install -d /usr/local/lib/pkgconfig
sudo tee /usr/local/lib/pkgconfig/lib3mf.pc >/dev/null <<'EOF'
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/lib3mf

Name: lib3mf
Description: An implementation of the 3D Manufacturing Format file standard
Version: 2.4.1
Libs: -L${libdir} -l3mf
Cflags: -I${includedir}
Requires.private: libzip zlib
EOF

And ensure pkg-config sees it (Arch uses pkgconf) pkgconf does not search /usr/local by default. Build with:

PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig" yay -S openscad-git

@mattaw it seems that lib3mf 2.4.1-1 breaks some CMake stuff, so until that's resolved all you do is to downgrade to lib3mf to 2.3.2-3

(This is my first AUR comment, hopefully its useful and at least semi-complete!)

I'm having an error about missing lib3MF after a clean build, but it is installed. Here are the prereqs successfully installed with yay -S openscad-git:

cachyos-extra-znver4/boost  1.89.0-3.2   187.05 MiB

Part of compile log with error:

I'd include the full log, but it doesn't look like you can hide it or attach as a file.

Just installed this package on a new installation. It requires flex and bison to be installed - should be added to the deps.

@gmhh, I added ".git", thanks @MrClear, you should report it upstream (though I think someone already did: https://github.com/openscad/openscad/issues/6243)

After last system update, I cannot see anything in the OpenSCAD view. Not even the axis. Same with openscad-qt6-git. openscad from extra works but is hopelessly outdated. openscad-snapshot-appimage works too but doesn't find the installed libraries.

This is the stderr output:

I cannot get this to build without editing

source=("$_pkg::git+$url.git")

into the PKGBUILD script as in @rc.poison 's comment

I get an error that I'm not on a branch if don't, but it builds perfectly fine if I do.

If I use an aur helper like yay, I get :

error fetching openscad-git: You are not currently on a branch.
