Arch Linux User Repository

I've worked out the patch for this, and modified the PKGBUILD accordingly. So please consider the merging https://github.com/strawpants/ncview-aur in this aur repo.

On another note: when starting ncview on gnome + wayland. Xwayland caused the ncview-interface to be way too small (+ tiny font). I've removed the xwayland-native-scaling option from the org.gnome.mutter experimental-features and now this seems to work okay again.

@graziano could you properly format your patch?

Patch to compile with gcc 15.2.1.

Just adding some detail on the error

Error: Aborting: no font found

If you cannot use /usr/share/X11/app-defaults/Ncview as described by @lmingari, you can set

export XAPPLRESDIR=$(readlink -f ~/my/path) # relative path not allowed
echo "Ncview*font: fixed" > ${XAPPLRESDIR}/Ncview

instead.

Hi

Thanks a lot for help

I was finally able to solve it by setting:

Ncview*font: fixed

in /usr/share/X11/app-defaults/Ncview. The font can be any of those listed by the xlsfonts command.

I got the same font error as Living. I have the package xorg-fonts-misc. What worked for me was editing /usr/share/X11/app-defaults/Ncview, and changing the line Ncview*font: -*-lucida-bold-r-*-*-14-*-*-*-*-*-*-* to Ncview*font: -*-*-bold-r-*-*-14-*-*-*-*-*-*-* I don't know which font it picks up, but it's usable.

After a recent update it no longer works. Tested in wayland+hyprland. This update required two new dependencies

• xorg-fonts-alias-misc
• xorg-fonts-misc

And ncview aborts with message:

Error: Aborting: no font found

I've been using ncview for a while successfully, today after updating I could no longer use it. I checked my pacman logs and saw only a few packages update (gstreamer, gst-plugin-base-libs, gst-plugin-bad-libs, gst-plugin-bad, gst-plugin-base, gst-plugin-good). I tried running ncview from a cluster (via X11 forwarding) and it also didn't work.

The error I'm getting is the exact message that Living's post shows. I already have xorg-fonts-misc installed. I'm using wayland/hyrpland. I found a similar post (https://forum.endeavouros.com/t/ncview-missing-fonts-in-wayland/63258) which seems to be unanswered.

I installed and ran ncview (2.1.8-1) ok, and got the warning about FontStruct, but the interface was in some weird language... Installing xorg-fonts-misc fixed my problem as well, although I still get the warning, the interface fonts are ok now. Thanks @OdinEidolon for sharing your fix.
