Hi again,
Just as a followup to anyone reading this thread, the problem was that Nim
loads shared libraries on Linux with dlopen by using only the RTLD_NOW flag.
The solution was to add the global flag when calling dlopen, like so: libHandle
= dlopen(myLibrary, RTLD_NOW | RTLD_GLOBAL), which is needed for GTK to find
all of it's needed libraries. This fixes the problem.

@Eric, @Antonio
Thanks for the suggestions. I was not completely accurate with the example I
gave. The code is equivalent, but it is written in Nim
(nim-lang.org<http://nim-lang.org>), which compiles to C and which I thought
should be the same as pure C.
So I tried the same example directly in C and it works. So the problem is
somewhere on the Nim side of things.
Thanks again for the help.
Matic

It seems that's something weird going on with your fonts. Sorry I have no
experience with your system.
Try another application just to show the list of installed fonts, maybe you
got some clue.
Best,
Scuri

Hi Antonio,
Thanks for the reply. I tried creating a IupFontDlg with:
Ihandle* dlg = IupFontDlg();
IupPopup(dlg, IUP_CURRENT, IUP_CURRENT);
but the code throws a segfault at the second line along with these errors
(shutdown is the name of the application):
(shutdown:19761): Gtk-WARNING **:
/home/pi/gtk+3.0-3.22.11/./gtk/gtkliststore.c:516: Invalid type (null)

... then a SEGFAULT occurs.
I have no idea what is going on?

Hi,
Thanks.
Probably those fonts (or its maps to the native names) are not installed or
available on that system.
Arial exists only in Windows, but Courier should be mapped to Monospace, and
Sans in already a GTK name. But I'm not familiar with Raspbian, so maybe we
need to map to specific fonts there.
Try displaying the IupFontDlg to see the actual list.
Best,
Scuri

Hello,
First a thank you to the creators of IUP. It's a wonderful library!
I have a simple application with a IupText and IupButton on a IupDialog that
works perfectly on Windows and most Linux distributions.
But on the RaspberryPi 3 (Raspbian OS) the font cannot be changed on either
IupText or IupButton. I tried many different font families and sizes and
nothing seems to work. Examples that I tried:
IupSetAttribute(textbox, "FONT", "Courier 30")
IupSetAttribute(textbox, "FONT", "Sans 18")
IupSetAttribute(textbox, "FONT", "Arial 30")
The font always seems to stay at "PibotoLt 12" and I have no idea why?
Any ideas?
Thanks,
Matic
