	Thank you for the information.  As luck would have it, I
thought of that when I built our Freebsd system here at work and
I did build it to be able to run Linux binaries.  Right now, the
problem is that I can't get it to compile on Linux either
although it looks like all I need is a library that contains
curses.h and readline.h.  I ran dselect on the Linux system and
found a libcurses which is part of the ruby scripting language,
but after installation of ruby, nothing changed.

	I am not sure what library I need on the Linux system but
that is probably all that stands between success and failure.

	If you hadn't reminded me about FreeBSD being able to run
Linux binaries, I might have not even thought of that right now.

	You are absolutely correct on the cause for the curses
problems.  Earlier today, one of the people working on the
development of this project wrote me and suggested the same
thing.  I do have the TERM environmental variable set, but it is
set to vt100 because I use MSKermit which emulates a vt320
terminal.  vt320 is a superset of the vt100's and vt102's.  You
usually can't go too wrong if you choose that setting.

	He suggested I try ansi as one of the terminal types and
so far, so good.
	I tried netrik on one of our javascript-run sites
produced by Lotus Notes, actually Lotus Domino which is what they
call their web authoring device and I think I see the dawning of
a new day.  This is definitely an effort which may turn out to be
something big.

	The authors say in several places that this is new code
and I noticed that one of the files I downloaded on Friday had a
date of the day before.

	These folks who have started this project have gotten off
on the right foot as far as I can tell and we should all be
patient and, if you can, roll up your sleeves and help grow it in
to a good mature application.

	The code is neat and modular from what little I have
looked at it and the documentation explains how it works.

	I got excited for a second and looked around on my system
for wget.  I do have it and it appears to be intact.  I wouldn't
normally do this, but the failure is so close to the beginning, I
will post the gdb trace.  It is during the initialization of
curses and it looks like maybe something isn't initialized that
should be at this point.

	I am glad to hear you got it running, Janina.  I haven't
worked with curses before and I bet this is something fairly
obvious.

	P.S. I have used curses many times in my life, even long
before I knew about computers.  I couldn't resist that.  Here is
the trace.

main (argc=2, argv=0xbffffcf4) at main.c:59 /*Normal up to here.*/
59            page_width=init_curses();
(gdb) step
init_curses () at screen.c:110
110        if(setaf!=NULL) return 0;    /* already initialized */
(gdb) print setaf
$1 = 0x0
(gdb) next
112        if(setupterm(NULL, 1, NULL)==ERR) {    /* init */
(gdb)
117        setaf=tigetstr("setaf");    /* control sequence to set foreground co/
(gdb)
118        setab=tigetstr("setab");    /* background color */
(gdb) print setaf
$2 = 0x0
(gdb) step
119        cuf1=tigetstr("cuf1");    /* move cursor right */
(gdb)
120        width=tigetnum("cols"); /*That did set to 80. Great!*/
(gdb)
121        if(setaf==NULL || setab==NULL || cuf1==NULL || width<=0) {
/*if any of those are 0, we are in trouble and we appear to be.*/
(gdb)
122           fprintf(stderr, "error initializing curses\n");

	I added the comments about width being set to 80 and also
the one about the reason for the initialization error, but that's
really as far as it gets.

	Too bad about no ssl support yet.  I am sure that is
because it is so new.  When I get it working, there are several
sites I am going to test it on that don't require ssl, but it
will definitely need ssl to hit any sensative we b pages.

	There is a man page on curses on the FreeBSD systems I
use at work and you do have to initialize the curses routines
with variables when you use them.

	This means that there is some kind of problem in the way
netrik is calling the routines.  I sent a message to one of the
developers and have not received a response yet, but I bet I do
get one eventually.

	This is quite normal for new software.  Most of the stuff
I write at work only has to transplant between 2 or 3 different
systems and there is still more than enough trouble in getting it
working everywhere it is supposed to work to keep ones head
buzzing.

	I am confident that the problems I am having right now
are temporary.  No telling how well this software will work on
our problem sites when the kinks get worked out of simply running
it, but this is the best effort to come along in a long time.  It
obviously worked for the people who wrote it on their linux
systems so the trick here is to figure out what is different
about their systems and the one I am using (actually two
different boxes but running the same software).

	Later on, I imagine that netrik will have more automation
built in to the make process to better configure everything at
the start.  I wouldn't be a bit surprised if my systems are
lacking some environmental variable setting or something like
that.  Stay tuned for more exciting adventures on the cutting
edge.

	Now I have had some time to try it out and so far,
nothing yet.  On the Linux system, I get an immediate error
message that says that it can't initialize curses.  I didn't know
you had to initialize curses.

	Thank you a hundred times.  Those two libraries were all
I needed.

	I haven't had a chance to read the instructions or try it
out, but I have a compile now.

	Has anyone gotten netrik to work?  netrik is a new text
browser which is free and open-source.  You can read about it at

http://netrik.sourceforge.net/

	It has limited javascript support and will run in a text
environment like lynx.

	Now for the bad news, at least so far.  I have access to
two different UNIX platforms.   One is Debian Linux and the other
is FreeBSD.  The readme file with netrik says that it is designed
to build on gnu linux systems.  One should just type make and it
will go.

	Well, on the FreeBSD system, it complains about 2 lines
in the makefile not having arguments that they need.

	On the linux system, it says:

cc -g -Wall  -DDEBUG -DREADLINE '-DWGET_CMD="wget -nv -O- %s"'   -c -o 
main.o main.c
main.c:16: curses.h: No such file or directory
main.c:22: readline/history.h: No such file or directory
main.c:23: readline/readline.h: No such file or directory
make: *** [main.o] Error 1

	That error I understand in that I am missing a library
containing the files that are listed as missing.  The make file
has an option to build on Solaris which is similar to FreeBSD so
I tried that but with no luck either.  Make just complained about
the same two lines needing arguments.

	I have a feeling this is about to compile but I have
either failed to set an environment variable or that I need to go
get a library somewhere that contains the correct headers.

	This project sounds like the folks who are working on it
are headed in the right direction so I am certainly willing to be
patient and find out why it isn't compiling right now.

	The current version appears to be netrik-0.7.1.tar.gz

	I would certainly like to see it run and play with it a
bit andfind out whether it might read some of our
javascript-infested web sites we have here.  They are not
terribly complex or special except that they use javascript to
set up the links and onclicks to tell the sites what link you
want.
