Message-Id: <201607032127.u63LRPVq023519@delorie.com> Date: Sun, 03 Jul 2016 21:40:05 +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: Release 6 of the DJGPP port of tcp/ip library Watt-32 (version 2.2 dev-rel. 10) uploaded. Content-Type: text/plain; charset=ISO-8859-15; format=flowed Reply-To: djgpp AT delorie DOT com This is the Watt-32 2.2 tcp/ip library compiled with DJGPP. Watt-32 is a library for making networked TCP/IP programs in the language of C and C++ under DOS and Windows-NT. Both 16-bit real-mode and 32-bit protected-mode is supported. For DOS, Watt-32 requires a packet-driver (PKTDRVR) to access the data-link layer. Futher information about this library can be obtained at: 1. DJGPP specific changes. ======================= This source archive (wat3222sr6.zip) has been created combining watt32s-Jan-2016.zip and small parts from watt32b.zip. Both have been downloaded from: This source archive contains the complete content of watt32s-Jan-2016.zip and the djgpp specific makefiles from the /bin directory of watt32b.zip together with ping.c, tiny.c and tcpinfo.c. That source files are the ones required to build ping.exe and tcpinfo.exe These two programs are probably the most important ones to make a very first check if the library and the network connection do really work. I have not tried to build any of the other programs stored in watt32b.zip. The may work or not. If you need them, you are alone. If you really want to build them, download watt32b.zip and copy the /bin directory into the directory tree created by wat3222sr6.zip archive. Please, pay attention to NOT replace the DJGPP specific makefiles provided by wat3222sr6.zip. The dj_err program has been recompiled. This is necessary to produce an up-to-date sys_errlist[] for the different versions of djgpp. The test programs stored in /src/tests have not been tested by me. They can be compiled without errors but I cannot tell how usefull they may be on plain DOS and/or some version of Windows. I have tested this library only on MS-DOS 6.22 using VMware. I have created a NAT network connecting two identical MS-DOS VMWare clones configured by DHCP. Only ping test were made. For DOS, a packet driver is required. I have used the one stored in pcntpk.zip. I do not remember from where I have downloaded it, but anyway you need to install the pocket driver that matches the network hardware you are using so you are alone here again. The wattcp.cfg file used has a single line like this: my_ip = dhcp Writing a wattcp.cfg that works for your network environment is your task. I cannot help you. I have _NOT_ tested the library with any windows version. The /bin directory contains all configuration files like wattcp.cfg, etc. provided by watt32s-Jan-2016.zip. I have not modified them. You must adjust them according to your network hardware anyway. Here you are alone. Please, read the original documentation. I have no major experience neither using Watt-32 nor using DJGPP for DOS networking. Please do __NOT__ mix libraries compiled with different versions of DJGPP. 2: Installing the binary package. ============================== Copy the binary distribution into the top DJGPP installation directory and unzip it running *ONE* of the following commands: unzip32 wat3222br6.zip or djtarx wat3222br6.zip or pkunzip -d wat3222br6.zip It will create a /watt directory into the top DJGPP installation directory. To use the binaries produced with this library you must set the WATTCP.CFG environment variable to point to the directory containing the wattcp.cfg file. E.g.: set SET WATTCP.CFG=c:\djgpp\net\watt\bin This file must be adjusted according to your network. To use the headers and library in your own projects, you must set the WATT_ROOT environment variable to point to directory where the /inc and /lib directories are. E.g.: set WATT_ROOT=c:\djgpp\net\watt Of course, the "c:\djgpp" part of the string must be adjusted to reflect the path where you have installed the binaries, headers and library. To be able to compile projects that use this library, you must set the following gcc environment variables: set C_INCLUDE_PATH=c:/djgpp/net/watt/inc set LIBRARY_PATH=c:/djgpp/net/watt/lib If you have installed and configured everthing correctly you can start the tcpinfo program like this: redir -eo c:\djgpp\net\watt\bin\tcpinfo.exe > 1.txt and inspect its output. Please note that "c:\djgpp\net\watt\bin" is usually not in your %PATH%. For my installation I get the following output: --------- START --------- Waterloo TCP/IP setup Reading configuration file `c:/drivers/net\wattcp.cfg' Warning: %WATT_ROOT% contains forward ('/') slashes. This may break some Makefiles. Warning: %WATTCP.CFG% contains forward slashes ('/'). This will break non-djgpp Watt-32 programs.

I have not tested with any previous versions of these binaries. Especially I have not tried any versions previous neither of gcc346 nor of bnu226. I have no intentions to support any older versions of the compiler and binutils. All these packages can be found in the v2gnu directory of ftp.delorie.com and any mirror. Create a temporary directory. Copy the source package: wat3222sr6.zip into the directory and unzip it running ONE of the following commands: unzip32 wat3222sr6.zip or djtarx wat3222sr6.zip or pkunzip -d wat3222sr6.zip Set the WATT_ROOT environment variable. It must point to the directory where the /src/makefile.all is stored. E.g.: if the source archive has been unziped in z:/tmp, then WATT_ROOT must be set to: set WATT_ROOT=z:\tmp\contrib\watt cd into /contrib/watt/util and run the command: make -f errnos.mak dj_err.exe This binary is required by the build process of the library. cd into /contrib/watt/src and configure the sources by running the batch file: configur.bat djgpp This will create the required makefile for DJGPP and all other required files to compile the library. Now you can build the library by running the command: make -f djgpp.mak After having build the library, you can build the binaries ping.exe and tcpinfo.exe. To this purpose, cd into /contrib/watt/bin and run the command: make -f djgpp.mak ping.exe tcpinfo.exe There is no installation target in the makefiles. You can create a directory where you want to install the library. Make a /bin, /inc and /lib directory. Copy the *.cfg files from the /contrib/watt/bin into the new /bin directory, copy the contents of the /contrib/watt/inc directory into the new /inc directory _preserving_ the directory tree. Copy libwatt.a from /contrib/watt/lib into the new /lib directory. Then set C_INCLUDE_PATH and LIBRARY_PATH environment variable to point to the directory where the library and headers have been installed. Also set the WATTCP.CFG environment variable to point to the directory where wattcp.cfg has been stored. The port has been compiled using djdev205 and consists of two packages that can be downloaded from ftp.delorie.com and mirrors as (timestamp 2016-06-06): Watt-32 (version 2.2 dev-rel. 10) binaries, headers, library and docs: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/wat3222br6.zip Watt-32 (version 2.2 dev-rel. 10) source: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/wat3222sr6.zip Send suggestions and bug reports concerning the DJGPP port to comp.os.msdos.djgpp or .
