It seems only the sample.c causes this error reported to the console.
Other IUP examples don't generate this error message.

Antonio,
I compiled with gcc the sample.c example and received this error in
the
console window.

G'day,
Not verified, but an easy thing to check:
The X/11 Windowing system is client/server-based. An
application(client)
may run locally, or perhaps across a network. GNOME and Wayland add
more
layers to the mix.
I tried:
You might have problems if the terminal/shell does not have a
reference to the X/11 windowing system,
supplied via the DISPLAY and XAUTHORITY environment variables. This
is what I get on my system
(ignore the "$" shell prompts):
$ set | grep -E DISPLAY
DISPLAY=:0
GNOME_SETUP_DISPLAY=:1
WAYLAND_DISPLAY=wayland-0
$
The trivial examples (called via Lua "require" interface) work with
this setup.
If I stomp on WAYLAND_DISPLAY, then the "hello, world" example fails:
$ export WAYLAND_DISPLAY=
$ ./hello-world
../support/lua5.1: IupOpen: could not initialize
stack traceback:
[C]: ?
[C]: in function 'require'
./hello-world:2: in main chunk
[C]: ?
$
Hope this helps.
s-b etc.
