Problem when using NCurses

Hi,

I try to use NCurses with GNU Smalltalk but I have some difficulties.

I have downloaded the version 3.2.5 of GNU Smalltalk and compiled it on a
Debian server (8.3 - 64 bits).

Gst works fine but if I try to use NCurses with the code:

PackageLoader fileInPackage: 'NCurses'.
NCWindow clock

I got the following error message:

Object: CFunctionDescriptor new: 1 "<0x7f23abdbb2c0>" error: Invalid C
call-out initscr
SystemExceptions.CInterfaceError(Exception)>>signal (ExcHandling.st:254)
SystemExceptions.CInterfaceError class(Exception class)>>signal:

NCWindow class>>primInitScr (NCurses.star#VFS.ZipFile/ncurses.st:1)

NCWindow class>>clock (NCurses.star#VFS.ZipFile/ncurses.st:2712)
UndefinedObject>>executeStatements (a String:1)
nil


libncurses is already installed in my system and I have no error at
compile time.

Someone has an idea ?

Best regards

Olivier
