Hi,

I've the same issue for several programs.

I'm using sway and I tried to use dino.

I've built dino like that:
> guix install dino \
> 	--with-debug-info=gtk \
> 	--with-debug-info=glib \
> 	--with-debug-info=glibc \
> 	--with-debug-info=libepoxy
> 
> cat $(which dino) | sed 's#exec -a "$0" #exec -a "$0" gdb #g' > dino
> chmod +x dino

And here's my gdbinit:
> $ cat ~/.gdbinit 
> guile
> (use-modules (gdb))
> (execute (string-append "set debug-file-directory "
>                         (or (getenv "GDB_DEBUG_FILE_DIRECTORY")
>                             "~/.guix-profile/lib/debug")))
> end

Then I run ./dino and I get that:

So for some reasons it fails in libepoxy.

So I tried to reproduce the issue:

And there it works:

But it somehow fails in my gdb sessions:

All the above is in Guix system.

The libGLESv2.so.2 comes from libglvnd, but libglvnd is not a
dependency of dino, and I only installed libglvnd with 'guix
package -i libglvnd' and dino is wrapped, so maybe for some reason
it doesn't find libglvnd.

I've tried to add libglvnd in dino inputs, but I got the same error
message (I didn't look at it with gdb though).

But if I install dino with Guix on top of parabola (a host
distribution) then it works fine.

I've also found out that gnome-weather was also complaining about a
missing libGLESv2:
> $ gnome-weather 
> Couldn't open libGLESv2.so.2: libGLESv2.so.2: cannot open shared object file: No such file or directory
> Aborted
but I didn't try to debug that.

Probably many more applications (than dino and gnome-weather) are
broken on Guix system.
