I tried placing these in the Makefile, to no avail -the resulting
image was stripped. However, I got a debug image running cargo in the
work directory; I only had to use it with
LD_LIBRARY_PATH=/usr/pkg/lib. When I run the debug version, I get:

$ rio-debug
xkbcommon: ERROR: couldn't find a Compose file for locale
"en_GB.UTF-8" (mapped to "en_GB.UTF-8")
thread 'main' panicked at
/usr/pkgsrc/wip/rio/work/rio-0.1.1/sugarloaf/src/context/mod.rs:92:55:
called `Result::unwrap()` on an `Err` value: CreateSurfaceError {
inner: Hal(FailedToCreateSurfaceForAnyBackend({})) }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I don't get a rust backtrace with RUST_BACKTRACE=full, as it doesn't
ever complete - it creates the window which contains a rectangle from
the terminal window I am starting it from and eventually freezes, I
have to let the wm kill it.

If I run the debug version under gdb, the trace is as follows:

I could never get the debug version to actually work. The non-debug
version works if invoked like

rio --command /bin/sh

Then the window comes up, furst time with some initial message and
then directoy to the prompt. The terminal type is rio, which I can't
use when I tic rio.terminfo I've got from a few months ago, I get many
unknown fields. I can set TERM to xterm-256color, though.

From now on, I can run /bin/vi, that's ok. Almost anything else that
deals with the terminal crashes rio - e.g. any fancy shell like ksh,
ksh93, fish, elvish, zsh, nu or tmux immediately crashes rio.

If I use sudo, e.g. sudo zsh, that works, I get fully working root zsh
and  I can start any other shell as root, including tmux, where I can
then su back to my user account, which works as expected. So it is
some weird (orr not...) protection issue. Once under root, rio works
as expected, with the exception of the jagged lines I mentioned before
if one has weird prompt like from starship.

Weird.
