Dear Gaius
Sorry for another mail from me about the usage of the ncurses.def to
enable "clear()" of the working terminal.
I copied the ncurses.def file into the directory where I do the
compilation. I imported the clear functionality from it.
Than my Modula-2 file nicely compiles, but it does not link:
gm2 -g -I.
-I/home/slotboom/opt/lib/gcc/x86_64-pc-linux-gnu/8.2.0/m2/pim
-I/home/slotboom/opt/lib/gcc/x86_64-pc-linux-gnu/8.2.0/m2/log
-I/home/slotboom/opt/lib/gcc/x86_64-pc-linux-gnu/8.2.0/m2/min
-flibs=pim,log -fmakeall ./SpinSimMain.mod
make: Nothing to be done for 'SpinSimMain'.
/tmp/ccDs7BDg.a(SpinSimMain.o): In function `Define_Batch':
/home/slotboom/development/DEF_SIMU/./SpinSimMain.mod:1531: undefined
reference to `clear'
collect2: error: ld returned 1 exit status
I have:
*libncurses.so.5*
and a
*libncursesw.so.5*
in the /lib/x86_64-linux-gnu directory and the .bashrc
*LD_LIBRARY_PATH* includes this directory.
One questions I have therefore:
- are these the libraries I need to link the application to get the
"clear()" function working, or do I need another ncurses library to be
installed?
Have a nice evening,
Hans
P.S. I have in the meantime got another MODULA-2 application working
(apart from the clear() function) and am very happy with it!

Hi Hans,
yes the special character codes are not interpreted (yet) in
Display/Terminal. This could be added though. At present there is a
substitute - which is to use the ncurses.def found in the examples:
http://git.savannah.gnu.org/cgit/gm2.git/tree/gcc-versionno/gcc/m2/examples/ncurses/ncurses.def
there are a few tiny example programs in the same directory.

it should be possible to use pim, iso and log in a single application.
The ulm is probably best to work with alone (or maybe with pim).
If you
use coroutines then you have to decide on a particular paradigm
and not
mix them :-). In conclusion they are designed to work together but if
the modules utilise aspects of SYSTEM.def/mod which contain different
declarations of the same named entity then problems arise,
hope that helps,

Gaius
