Message-Id: <201707161626.v6GGQF6A027947@delorie.com> Date: Sun, 16 Jul 2017 14:43:59 +0200 From: "Juan Manuel Guerrero (juan DOT guerrero AT gmx DOT de) [via djgpp-announce AT delorie DOT com]" To: djgpp-announce AT delorie DOT com Subject: ANNOUNCE: DJGPP port of Lynx 2.8.9dev.16 uploaded. Content-Type: text/plain; charset=ISO-8859-15; format=flowed Reply-To: djgpp AT delorie DOT com This is a port of Lynx 2.8.9dev.16 to MSDOS/DJGPP. Lynx is a fully-featured World Wide Web (WWW) client for users running cursor-addressable, character-cell display devices such as vt100 terminals, vt100 emulators running on character-cell display. It will display Hypertext Markup Language (HTML) documents containing links to files on the local system, as well as files on remote systems running http, gopher, ftp, wais, nntp, finger, or cso/ph/qi servers, and services accessible via logins to telnet, tn3270 or rlogin accounts. DJGPP specific changes. ======================= This port is based on the current develop code of lynx (aka lynx2.8.9dev.16) available as: http://invisible-island.net/datafiles/release/lynx-cur.tar.bz2 The code has been adjusted to detect at runtime if LFN support is available or not. If LFN support is available then the original posix style file names will be used else DOS compatible ones will be used. The port will use cp850 as default code page instead of using iso-8859-1 as it is in the current code. It is clear that having iso-8859-1 on plain DOS as character set is useless as soon as spanish, german or other non-english texts shall be displayed. You can always select another character set by either setting the corresponding environment variable or by editing lynx.cfg acordingly. The current version of lynx requires that the HOME environment variable is set to a writable directory or it will refuse to start. To alleviate this situation, if HOME is not set, the current directory will be used instead by this port version. The port has been configured using the configure script provided by the source package. This means that neither old DJGPP specific scripts nor makefiles distributed by the package have been used. A lot of the porting work has been invested in the DJGPP specific configuration scripts. This port has been configured to be compiled with BZIP2, ZIP and PDCURSES support. This means that if you want to recompile the preconfigured sources you must have installed the following ports: ftp://ftp.delorie.com/pub/djgpp/current/v2apps/bz2-106ar2.zip ftp://ftp.delorie.com/pub/djgpp/current/v2tk/zlb1211b.zip ftp://ftp.delorie.com/pub/djgpp/current/v2tk/pdcur34a.zip The port has been configured and build without NLS support enabled. To enable this feature, the latest ports of libiconv and gettext must be installed: ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/licv114br2.zip ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/gtxt192b.zip If you prefer NLS, then reconfigure the sources passing the nls flag to the config.bat file. The port has been configured with OPENSSL support. OpenSSL support requires installing the WATT-32 port. The following ports have been used: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/ssl102kb.zip ftp://ftp.delorie.com/pub/djgpp/current/v2tk/wat3222br6.zip No other versions have been tested. To be able to use this program compiled with OpenSSL and WATT-32 a noise source must be installed. A noise source can be obtained as: http://www.rahul.net/dkaufman/noise063a2.zip If for some reason you decide to reconfigure the source package, then you will have to set the WATT_ROOT environment variable to point to the directory where the headers and the library reside. This is: set WATT_ROOT=/dev/env/DJDIR/net/watt To be able to run the program, configuration files are expected to be found at their canonical place. This is the /dev/env/DJDIR/etc directory. The configuration files lynx.cfg and lynx.css are stored in the /etc directory and reflect, to certain extent, the conditions during the configuration and compilation process of this port. You may need to adjust the entries to fit your requiriments. If lynx.cfg and lynx.css are not found at their canonical place then the program will try to load them from the installation directory of lynx. To run the program, a working version of wattcp.cfg is required. This file is __NOT__ distributed with this port. That file will reflect your network environment and hardware. It is the user's job write one that matches his environment. As a starting point you can use the one distributed with the WATT-32 port. Please note that the location of wattcp.cfg must be specified by setting the WATTCP.CFG environment variable. This can be done either in the environment, in autoexec.bat or in djgpp.env. If the file cannot be found at any of the canonical places the program will try to load it from the installation directory of lynx. To be able to run the program, a DOS packet driver (PKTDRVR) is required. This may be obtained from the card manufacturer or from one of the archives of packet drivers (such as "http://www.lanet.lv/simtel.net/msdos/pktdrvr-pre.html" or "http://ftp.freenet.de/pub/ftp.simtel.net/pub/simtelnet/msdos/pktdrvr/"). Even when only browsing local files, a NULLPKT packet driver is required like nullpkt.zip. The zip file can be downloaded as: http://www.jumpjet.info/Application-Software/DOS/Hardware/2/NULLPKT/NULLPKT.zip The lynx executable itself handles http:, https:, ftp:, file:, news:, nntp: and gopher: protocols. You will need external programs if you want to access telnet:, tn3270:, or mailto: URLs. In this case a port of kermit may be required. Please note that lynx does _NOT_ support javascript at all. So nothing will work that requires this feature. If you need this, look for a different text web browser. It is important to realize that this port is a _PURE_ DOS port. If for some reason you want to use lynx under Windows, you should download a windows port of lynx. If you decide to use this port as stand alone program then you __MUST__ set the following environment variables to point to the required configuration files: LYNX_CFG Set to the full path and filename for lynx.cfg LYNX_LSS Set to the full path and filename for lynx.lss WATTCP.CFG Set to the full path for the WATTCP.CFG directory SSL_CERT_FILE Set to the full path and filename for your file of trusted certificates As a last resort, if the above environment variables are not set, the program will try to load those files from its installation directory. There is also a batch file stored in the /share/lynx_doc/samples directory that shows how to run lynx as a stand alone application. The DJGPP port now checks the OS version it is running on. If it is equal or less than MSDOS 6.22 the double quotes around the file name passed to edit.com will be removed. If this is not done, edit.com refuses to start. For OS like Win95 and above this is not necessary. edit.com is the editor used by lynx at last resort. The program's behaviour is not changed if an editor different from edit.com is selected in lynx.cfg. The DJGPP port now checks if LFN support is available. If available then files with a leading dot are allowed/supported in case that this has been allowed by setting NO_DOT_FILES to FALSE in lynx.cfg. In all previous versions, the setting of this value had absolute no influence in program's behviour if compiled with DJGPP. I have tested this port by trying to access all sites that are listed in: http://royal.pingdom.com/2012/06/25/using-web-browser-lynx-visit-top-websites/ and I have experienced no issues. I have also accessed some german and spanish sites to check if the special native characters are correctly displayed and I have found no issues. I have also accessed www.delorie.com to check if the ftp support works well and if the cvs repository can be accessed via cvsweb interface and everthing works flawlessly. Of course, the mail archives can also be accessed without issues. Please note that I am not a lynx user. I have ported it as a real world test for the OpenSSL and WATT-32 ports. As usual, all djgpp specific files (diffs, README files, etc.) are stored in the /djgpp directory. The sources have been configured to be build in the "_build" directory. If for some reason it does not work for you, delete it contents and configure from scratch again. Please read the docs very __CAREFULLY__ to become familiar with the product. Here is an extract of the NEWS file showing the user visible changes from the last port (Lynx 2.8.9dev.14) to this one: ------------------------------------------------------------------------------- 2017-07-10 (2.8.9dev.16) * modify configure script to warn if NLS cannot be configured, and disable the feature rather than leaving it partly configured and failing during the build -TD * modify configure script to allow pre-set $MSGFMT and $XGETTEXT variables to to used to build the NLS configuration using system's native NLS support -TD * convert po/zh_TW.po to UTF-8 to work with Solaris10, which lacks big5 -TD * build-fix for OSX Panther, which has PRId64 but not SCNd64 (patch by Martijn Dekker). * modify po-makefile to use msgmerge to align with lynx.pot, and also use sed to update some obsolete homepage URLs in translations -TD * add a note in the comments for INCLUDE in lynx.cfg regarding the default directory searches LYOpenCFG(), added in 2.8.4dev.20 (Debian #818047) -TD * add a check to ensure that HTML_put_string() will not append a chunk onto itself (report by Ned Williamson) -TD * update da.po, et.po, tr.po from http://translationproject.org/latest/lynx 2017-07-04 (2.8.9dev.15) * add note in lynx.cfg about default values (Debian #408448) -TD * amended Backes' change to the COLLAPSE_BR_TAGS feature for compatibility -TD + use ENABLE_LYNXRC to determine whether it is written to the .lynxrc file. + add command-line option, etc., for controlling whether blank lines are trimmed, e.g., trailing lines as well as the special case for collapsing br-tags. Leading blank lines at the top of the document are untouched. + modify limit for trimmed lines to retain as little as 1 line; previously the trimming would go no smaller than 2 lines. * add command-line option and options-menu item for COLLAPSE_BR_TAGS (patch by Peter Backes). * fix strict gcc7 warnings on OSX, aside from those due to incorrect system headers -TD * adjust definition of alloca() in HTUtils.h to quiet bogus compiler warning with NetBSD 7 -TD * add configure check for preprocessor -C option, overlooked in c99 -TD * correct logic in HTCopy() when re-reading a page (Debian #863008) -TD * fix lintian warnings in ".deb" test-package -TD * build-fix for PGI compilers, e.g., symbol conflicts -TD * update eo.po from http://translationproject.org/latest/lynx ------------------------------------------------------------------------------- The port consists of the usual three packages that have been produced using djdev205 and can be downloaded from ftp.delorie.com and mirrors as (time stamp 2017-07-15): Lynx 2.8.9dev.16 binaries, scripts and man format documentation: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/lx28916b.zip Lynx 2.8.9dev.16 html format documentation and sample files: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/lx28916d.zip Lynx 2.8.9dev.16 source: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/lx28916s.zip Send lynx utils specific bug reports to .
