Hello all,

I've just built ncurses 5.5 to try to use it with GNAT 3.15p on Linux.
The build went fine and it looks to me as though all the Ada files went
in the proper directories.

I'm trying to compile the rain.adb sample program from inside Emacs as
follows:

-------------------------------------------------------------------------------------------------------------------------------------
cd /home/adauser/ncurses-5.5/Ada95/samples/
cd /home/adauser/ncurses-5.5/Ada95/samples/ && gnatmake -o
/home/adauser/ncurses-5.5/Ada95/samples/rain rain -g -cargs -gnatqflo
-O -bargs -largs
gcc -c -g -gnatqflo -O rain.adb

GNAT 3.15p (20020523) Copyright 1992-2002 Free Software Foundation,
Inc.

Compiling: rain.adb (source file time stamp: 2003-10-25 15:39:18)
-------------------------------------------------------------------------------------------------------------------------------------

then a little further on:

-------------------------------------------------------------------------------------------------------------------------------------
45. with Terminal_Interface.Curses; use Terminal_Interface.Curses;
1 2


-------------------------------------------------------------------------------------------------------------------------------------

But when I look in the directory where all the Ada system includes are,
I see that the terminal_interface-curses body and spec files are
present but I don't see a spec or body for terminal_interface.

I'm missing something but as I'm new to Ada and GNAT (and a host of
other things as well) I don't know what it is. Can anyone shed any
light on this?

Thanks,
Rand

Maybe I am missing something but how is gnatmake supposed to find the
ncurses source code. Seems like a missing -I.

What directory does ncurses install the .ads files into?

I thought I found where the Ada system body and spec files were and had
the ncurses build install in the same directories.


I don't know what the defaults are. I used the ./config parameters to
specify the rts-native/adalib and adainclude directories in which I
found things like text_io.ali and text_io.adb and text_io.ads for
example.

But these files don't appear to be used after all. I renamed
text_io.ads to footext_io.ads and a test program that had with and use
clauses for Ada.text_io compiled and executed normally. So now I also
don't understand where it's finding the system files to compile with in
addition to my original problem.

Thanks,
Rand

Actually, those were the right libraries. I don't know why it wasn't
working. (I was indeed able to break the compilation by renaming
a-textio.ali in the rts directory.)

After some thought, I decided to put ncurses in its own two libraries
and set separate include and linker paths and it seems ok. The only
thing here is that compiling a program that withs curses support seems
to create copies of the curses .ali and .o modules in the source
directory, which seems objectionable since they already exist in the
adalib.

Cheers,
Rand

Try write-protecting the .ali in the Ada library, I think that's what
tells GNAT not to recompile.

Hi Simon,

Thanks, I read that also but it doesn't seem to apply here as I've
created the ncurses directories and chowned everything to root with R/O
permissions for world. But I may have outsmarted myself with something
else. I need to retrace my steps and check something in the next day
or two and if I can resolve it, I'll post again.

Meanwhile should any other ideas pop up please let me know.

Cheers,

Rand
