I think we can close this PR.

Run is fixed by using “unix.rs” and not “other.rs” (since freebsd isn’t listed) in cosmic-text:

So, this is a cosmic-text issue to be discussed with upstream about adding “freebsd” support to it.

Any sugestions to open an PR?

@nunotexbsd I just tried creating this symbolic link, and lapce still failed with no default font found :

sudo mkdir -p /usr/local/etc/fonts
ln -s /usr/share/defaults/fonts/fonts.conf /usr/local/etc/fonts/fonts.conf
lapce

Then I tried creating this symbolic link instead (after deleting the above non-working one):

sudo mkdir /etc/fonts
sudo ln -s /usr/share/defaults/fonts/fonts.conf /etc/fonts/fonts.conf
lapce

And that one worked! (At least with the nightly build of lapce.)
