 760       <p>Recently, Karl Bongers has put together a beta for win32
 761 using pre-built cygwin
 762 and Borland bins. You can download it <a href="ftp://sdcc.sourceforge.net/pub/sdcc/sdcc-2.2.2-7.11.01-winbin.zip">
 763 here</a>.
 764 Remember this is a beta build and will change from time to time.
 765 Updates
 766 will be posted in the <a href="index.php#Download">Download</a>
 767 section as they become available. There will be a link in the <a href="index.php#Download">
 768 Download</a> section for this and all future builds. Please *DO
 769 NOT* email Karl directly
 770 with problems. Any questions or fixes you have can be directed to the
 771 mailing
 772 list, see the link in the <a href="index.php#Support">Support</a>
 773 section below.<br />
 774       </p>
 775       <p>If you run a win32 box I recommend installing Karl's
 776 build, if only for the
 777 ease of install. If you are a native Linux user, use the CVS tree.
 778 Completely
 779 remove the old source dir and do a fresh checkout.</p>
 780       <p>As always, there is lots going on in CVS. There are a
 781 LOT of changes to
 782 the documentation. This has been and always will be a short side of
 783 OSS,
 784 SDCC included. The developers have added a lot of new command line
 785 switches
 786 and made changes to the old ones. The mcs51 header files have been
 787 removed
 788 and replaced with a common one. RTFM and then ask questions. The Z80
 789 port
 790 has been updated as well. Scott has fallen off the face of the earth
 791 and
 792 has not been heard from for a while ;-) We'll hear of his adventures
 793 when
 794 he returns. Meanwhile the PIC port has remained static. Michael has
 795 been
 796 working on an automated build for SDCC. If you download the source
 797 files,
 798 this should help tremendously.</p>
 799       <p>There are a few bugs left that are keeping the
 800 developers from releasing
 801 v2.2.2. This has been said now for a long time now. You just can't rush
 802 quality ;-) An <i>official</i> release should happen in
 803 the next few months.</p>
 804       <p>Special thanks to Johan Knol for keeping the ball
 805 rolling while everyone
 806 is working their paying jobs.</p>

 813       <p>There has been a <i><b>lot</b></i>
 814 of updates to v2.2.2 CVS lately. v2.2.1
 815 is comparatively old and we recommend you download a binary
 816 build from the <a href="http://www.qsl.net/dl9sec/SDCC_OKR.html">OKR</a>
 817 or update your sources from CVS. Mitja Kukovec has sent the mailing
 818 list
 819 some short instructions on installing Cygwin on a Win32 box, the link
 820 to
 821 the text is in the SUPPORT section.</p>

 827       <p><i><b>February 20, 2001 - Pic Port</b></i></p>
 828       <p>Scott has been making great strides on the pic port.
 829 There are a lot of issues
 830 with bringing his work into other branches of SDCC, so you will not see
 831 all
 832 of the features of his port in the avr and mcs51 trees. Scott has been
 833 working
 834 on generating intermediate 'pcode' that will be used for code
 835 optimizations
 836 and linker features. This is a major step and there are bound to be
 837 problems...
 838 on the cutting edge you might get cut every once in a while. This has
 839 not
 840 been implemented in any of the other trees, but if he pulls this off,
 841 you
 842 will see better and more flexible code come out of SDCC. We think it's
 843 just
 844 a matter of time ;-) Tip-o-the-hat to Scott.</p>
 845       <p>Sandeep's daytime job keeps him from doing as much as he
 846 would like, but
 847 he pops in from time to time with fixes and other contributions.
 848 Everyone
 849 involved with the project has been very active lately, we are a lot
 850 closer
 851 to an <i>official</i> 2.2.2 release. As always, the above
 852 can be had from
 853 cvs. It would be a good idea to do a fresh check-out from cvs rather
 854 than
 855 an update as a LOT of things have changed. Binary builds from recent
 856 cvs
 857 sources can be downloaded from the <a href="http://www.qsl.net/dl9sec/SDCC_OKR.html">

 865       <p><i><b>January 25, 2001 -- SDCC v2.2.2 is still in CVS</b></i></p>
 866       <p>Due to numerous additions to SDCC to support the Dallas
 867 DS'390, Version 2.2.2
 868 has been delayed until more bugs are squashed. Kevin and Johan are
 869 working
 870 on them all the time ;-) Lots of help from the user and development
 871 mailing
 872 lists too.</p>
 873       <p>Some (if not all) of SDCC users will be glad to know
 874 that Scott Dattalo has
 875 been porting SDCC to the 14bit versions of the Microchip PIC
 876 controller.
 877 His port is still in its early stages and needs a lot of work but it
 878 does
 879 compile programs. His code has been committed to cvs on sourceforge and
 880 is
 881 included when you update your cvs directories.</p>

 915       <p><i><b>V2.2.1 is in CVS</b></i></p>
 916       <p><i><b>(Sept 17,2000) </b></i>The
 917 latest version SDCC is in CVS at the moment. Michael Schmitt has been
 918 making releases and posting them to the supporting web sites,
 919 specifically the <a href="http://www.qsl.net/dl9sec/SDCC_OKR.htm">OKR</a>
 920 . As always... the most recent source code is here on Sourceforge. A
 921 lot of work is going into the flat 24bit model and the Dallas '390
 922 processor by Kevin Vigor. Kevin has been committing updates and fixes
 923 almost on a daily basis. '390 support is looking good. As soon as all
 924 the "known" bugs have been squashed, a release will be posted here in
 925 the download section.</p>
 926       <p>If you are using SDCC on a win32/Cygwin platform, be aware you
 927 will also need 'binutils' from the CVS tree.<br />
 928 Once logged into CVS do: cvs -z3 co binutils-avr<br />
 929       </p>
 930       <p>Some users are experiencing problems with win32/Cygwin logging
 931 into cvs. Compatibility issues on Cygwin and win32 versions of cvs will
 932 be posted soon. I will be contacting Cygnus to see if we can post the
 933 known working version of Cygwin here on Sourceforge.</p>
 934       <p>AVR support is continuing. Sandeep expects a usable build
 935 sometime before the end of October.</p>

 941       <p><i><b>V2.2.0 is now released. </b></i></p>
 942       <p><i><b>(Feb 27,2000)</b></i> SDCC
 943 v2.2.0 is coming soon. As of February 27, 2000, work on v2.2.0 is
 944 moving along but there are still a few compile problems to be worked
 945 out. This will be a big step in the development of SDCC as it will now
 946 support the Z80 with support for the Atmel AVR right behind it. The
 947 next few 2.x releases will be mostly bug fixes (if there are any ;-)
 948 and speed improvements.</p>
 949       <p>SDCC now has limited support for the Dallas DS80C390
 950 microprocessor using the --model-flat24 option. This is a processor
 951 from Dallas Semiconductor which starts up in 8051 code compatible mode,
 952 but has a new mode which allows direct, non-paging use of up to 4
 953 megabytes of code and data space.The TINI board from Dallas uses this
 954 processor and includes 512kbytes flash, ram + Ethernet on a small simm
 955 stick board for $50.00. See <a href="http://www.ibutton.com">http://www.ibutton.com</a>
 956 TINI for details.</p>
 957       <p>As of the first week in April, <a href="http://www.systronix.com">Systronics</a> is now
 958 shipping backorders for the STEP, STEP+, and the TINI. (Dallas must be
 959 selling a ton of the TINI's. I have one of the STEP+TINI kits and love
 960 it... I just finished getting an http server up and running on it)</p>
