Ideally you would never have to read this, but inevitably problems
|
|
Packit |
f574b8 |
do arise. As implementation and installation problems become known
|
|
Packit |
f574b8 |
they will be outlined in this file.

The install script will attempt to preserve your current settings in the
|
|
Packit |
f574b8 |
lynx.cfg file. You should review these (at the end of lynx.cfg) after
|
|
Packit |
f574b8 |
install. For instance references to lynx.browser.org for a startfile can
|
|
Packit |
f574b8 |
be removed, since that site is no longer maintained.

Some customized installs of OpenSSL are not detected by the configure
|
|
Packit |
f574b8 |
script. For example, with Redhat9, we did this to work around:
|

|

f574b8 |
#!/bin/sh

The configure script check for IPv6 (--enable-ipv6) assumes that your build
|
|
Packit |
f574b8 |
machine can listen for IPv6 connections. It cannot determine if you want
|
|
Packit |
f574b8 |
to use it only for outgoing connections. If the configure script is
|
|
Packit |
f574b8 |
otherwise successful, it will warn about a nonfunctioning getaddrinfo()
|
|
Packit |
f574b8 |
function, and does not define these symbols needed to successfully compile
|
|
Packit |
f574b8 |
IPv6 support. You can work around this by by editing lynx_cfg.h:
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
HAVE_GAI_STRERROR

Control-Z on Unix can cause aberrant behavior. If you encounter
|
|
Packit |
f574b8 |
problems, use -restrictions=suspend to disable it, and only '!'
|
|
Packit |
f574b8 |
for escapes to shell (on VMS control-Z is unconditional 'Q'uit,
|
|
Packit |
f574b8 |
with no attempt to suspend the Lynx process only temporarily).
|
|
Packit |

Screen resizing can be a bit funny. If you resize the screen,
|

Packit |
f574b8 |
documents that have been cached will be out of whack. Any further

documents will look fine. You can reload documents to the current

If the configure script dies when it discovers that gcc is broken,
|
|
Packit |
f574b8 |
despite the fact there is a perfectly good ANSI cc in the PATH,
|
|
Packit |
f574b8 |
try setting the CC environment variable to your working cc compiler
|
|
Packit |
f574b8 |
before running configure: e.g.
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
setenv CC cc (or set CC=cc; export CC , depending on the shell)

If you run into a problem compiling GridText.c, try omitting -O from the
|
|
Packit |
f574b8 |
compiler flags; it is a very big file and may not compile successfully

if you include optimization.

On a Sun system, the message:
|
|
Packit |
f574b8 |
"Alert!: Unable to connect to remote host"
|
|
Packit |
f574b8 |
will be displayed every time an attempt is made to access a host
|
|
Packit |
f574b8 |
other than localhost if Lynx has been built without the resolv
|
|
Packit |
f574b8 |
library and needed it, or with it and shouldn't have been.
|
|
Packit |
f574b8 |
Unfortunately, there's no way to check in the Makefile whether
|
|
Packit |
f574b8 |
-lresolv should be included in the LIBS="" list. What's necessary
|
|
Packit |
f574b8 |
depends on how that Sun is configured. To get the build right for
|
|
Packit |
f574b8 |
your SUN 3 or 4 OS, if you didn't have RESOLVLIB defined in the
|
|
Packit |
f574b8 |
Makefile define it and build Lynx again, or vice versa. Also, if
|
|
Packit |
f574b8 |
you have upgraded to the bind-8.1 or later library, you should try
|
|
Packit |
f574b8 |
changing -lresolv to -lbind.

On Sun systems when accessing sites that use multiple IPs for one URL,
|
|
Packit |
f574b8 |
you may experience a core dump. It's a bug in the resolver library,
|
|
Packit |
f574b8 |
which can be fixed by downloading & installing Sun's jumbo patch:
|
|
Packit |
f574b8 |
search Sun support information, e.g., Solaris newsgroups,
|

The Sun `shelltool' and `cmdtool' terminals are stupid by default.
|
|
Packit |
f574b8 |
In order to get bold text to appear differently than inverse video,
|
|
Packit |
f574b8 |
the user should put this line in ~/.Xdefaults:
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
Term*boldStyle: Offset_X
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
From the `shelltool' man page, it seems that an analogous line
|
|
Packit |
f574b8 |
in ~/.defaults
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
/Tty/Bold_style "Offset_X"
|
|
Packit |
f574b8 |
|
|
Packit |
f574b8 |
ought to work just as well, but you may not get the desired
|
|
Packit |
f574b8 |
behavior until you modify your .Xdefaults file (and run `xrdb
|
|
Packit |
f574b8 |
~/.Xdefaults'). Note also that there are other supported values
|
|
Packit |
f574b8 |
for the boldStyle resource/Bold_style default, all of which begin
|
|
Packit |
f574b8 |
with "Offset_". (helpful hint from kevin@traffic.den.mmc.com)

Directory browsing has been implemented for VMS, but there are no
|
|
Packit |
f574b8 |
plans to port additional DIRED support, because Lynx must handle files
|
|
Packit |
f574b8 |
as streams, and this precludes "serious" Directory/File Management on
|
|
Packit |
f574b8 |
VMS. Use a jumps file link to CSwing (sources or executables are
|
|
Packit |
f574b8 |
available from ftp://narnia.memst.edu), or define CSWING_PATH in
|
|
Packit |
f574b8 |
userdefs.h or lynx.cfg to invoke CSwing via the DIRED_MENU command.

Packit |
f574b8 |

The Mosaic v2.5 hostlist uses HTML similar to that of Lynx's bookmark
|
|
Packit |
f574b8 |
file, but with </HTML> at the bottom, such that it is not fully
|
|
Packit |
f574b8 |
compatible with Lynx's file. If you try to use the Mosaic file as if
|
|
Packit |
f574b8 |
it were a Lynx bookmark file, the </HTML> will not be taken into
|
|
Packit |
f574b8 |
account and new links will be added below rather than above those end
|
|
Packit |
f574b8 |
tags. Instead, add a link to the Mosaic file in your Lynx file, and
|
|
Packit |
f574b8 |
to the Lynx file in your Mosaic file, so that you can access both files
|

Packit |
f574b8 |
with both clients.

There is an apparently broken version of select() in libcurses.a

f574b8 |
of HP/UX 10.10. It also breaks tn3270, ncftp, emacs, and xemacs.

|
|
Packit |
f574b8 |
inappropriate video attributes on the Lynx displays (reverse video and

underscores on everything). Using "-lc -lHcurses" instead fixes the

notify the lynx-dev@nongnu.org list.

f574b8 |
Updated NOTE (1996-09-02): A patch reportedly is available from HP to
|
|
Packit |
f574b8 |
fix the select() problem, so that "-lc" is no longer needed, but
|
|
Packit |
f574b8 |
the curses glitch is not yet fixed, and you should still include
|
|
Packit |
f574b8 |
"-lHcurses".

Updated NOTE (1997-02-03): The problems reportedly are fixed with

Lynx juggles variable abilities of curses packages or emulations to
|
|
Packit |
f574b8 |
display bolding and underlining simultaneously. This may fail if
|
|
Packit |
f574b8 |
Lynx thinks that your terminal, in connection with the curses package,
|
|
Packit |
f574b8 |
supports a capability which the terminal hardware or emulation does not
|
|
Packit |
f574b8 |
in fact support. Setting the right TERM environment variable, tweaking
|
|
Packit |
f574b8 |
terminfo or termcap files, or compiling with a newer version of ncurses
|
|
Packit |
f574b8 |
or slang may solve problems with missing highlighting or strange
|
|
Packit |
f574b8 |
characters appearing on the screen. Also, for a mono terminal,
|
|
Packit |
f574b8 |
make sure "show color" is not set to ON in the Options Menu.

The Wyse 50 and older TeleVideo terminals, among others, are
|
|
Packit |
f574b8 |
"magic cookie" terminals. This means that display attributes like
|
|
Packit |
f574b8 |
reverse, blink, underline, etc. work in a bizarre way that makes them
|
|
Packit |
f574b8 |
difficult to program. You may see extra spaces scattered around your
|
|
Packit |
f574b8 |
screen (separating different sorts of highlight); or sections of the
|
|
Packit |
f574b8 |
screen may be unexpectedly highlighted.
|
|
Packit |
f574b8 |
There is a workaround which works by restricting the terminal to a
|
|
Packit |
f574b8 |
single standout attribute (e.g., normal and reverse, but no others).
|
|
Packit |
f574b8 |
Implementing the workaround is specific to your curses implementation.
|
|
Packit |
f574b8 |
Most versions of curses use one of two terminal databases, called
|
|
Packit |
f574b8 |
"termcap" and "terminfo". Updating these databases is system-specific.
|
|
Packit |
f574b8 |
New databases should be available from the vendor or other sources.
|
|
Packit |
f574b8 |
For the Wyse 50, try

|
Packit |
f574b8 |
<URL: http://www.wyse.com/text/custserv/faq/wy50faq.htm>;
|
|
Packit |
f574b8 |
extract the "wy50" (NOT "wy50-mc") entry and use that in place of the
|
|
Packit |
f574b8 |
existing one. See `terminfo', `infocmp', `tic' etc. man pages if
|
|
Packit |
f574b8 |
necessary.
|
|
Packit |
f574b8 |
Alternatively, compiling Lynx with the slang library may avoid problems

f574b8 |
with theses terminals.

The Sun console driver (aka wscons(7)) implements "reverse" and "bold"
|
|
Packit |
f574b8 |
as "reverse", causing confusion where Lynx uses the distinction between
|
|
Packit |
f574b8 |
the two to convey information. Lynx tries to detect this automatically,
|
|
Packit |
f574b8 |
but if it fails (for instance, you are running under "screen"), try
|
|
Packit |
f574b8 |
setting the -noreverse commandline option.

On VMS, Lynx, and other TCP-IP software, have been experiencing chronic
|
|
Packit |
f574b8 |
problems of incompatibilities between DECC and MultiNet headers whenever
|
|
Packit |
f574b8 |
new versions of either DECC or MultiNet are released. The Lynx build
|
|
Packit |
f574b8 |
procedure for VMS and a maze of spaghetti #ifdef-ing in tcp.h of the
|
|
Packit |
f574b8 |
libwww-FM had previously been successful in dealing with this problem
|
|
Packit |
f574b8 |
across all versions of MultiNet and of DECC, VAXC, and Pat Rankin's
|
|
Packit |
f574b8 |
VMS port of GNUC, but are now not 100% successful. If you get compiler
|
|
Packit |
f574b8 |
messages about "struct timeval timeout" having no linkage, add that
|
|
Packit |
f574b8 |
declaration immediately below the inclusion of ioctl.h for MultiNet in
|
|
Packit |
f574b8 |
tcp.h (by deleting the "#ifdef NOT_DEFINED" and "#endif /* NOT_DEFINED */"
|
|
Packit |
f574b8 |
lines):
|
|
Packit |
f574b8 |

Packit |
f574b8 |
#include "multinet_root:[multinet.include.sys]ioctl.h"

If you get compiler warnings about incompatible multinet_foo()
|
|
Packit |
f574b8 |
declarations, delete those where indicated in tcp.h. For the most
|
|
Packit |
f574b8 |
current versions of MultiNet, you can modify tcp.h to use the DECC
|

Packit |
f574b8 |
socket and related headers.

On VMS, the ftp function does not work with SOCKETSHR 0.9D and NETLIB
|
|
Packit |
f574b8 |
2 (NETLIB 1 may work). This is because the functions getsockname()
|
|
Packit |
f574b8 |
and getpeername() within SOCKETSHR make incorrect calls to the NETLIB
|
|
Packit |
f574b8 |
functions. This results in zeroes being returned for part of the local
|
|
Packit |
f574b8 |
IP address. Since ftp sends this IP address to the remote end, the
|
|
Packit |
f574b8 |
remote server ends up sending a file back to a non-existent address.

On VMS, to build an SSL-capable version, lynx and the ssl library
