Description:

T2 SDE is not just a regular Linux distribution - it is a flexibleOpen Source System Development Environment or DistributionBuild Kit (others might even name it Meta Distribution). T2 allowsthe creation of custom distributions with state of the art technology,up-to-date packages and integrated support for crosscompilation. Currently the Linux kernel is usually used, but we alsoconsider to port T2 to support compiling home-brew open source packageadd-ons on macOS, other BSDs, classic Unix systems (Irix, ...) orsupport bootstrapping alternative micro kernel systems (like a L4variant or Fuchsia). Similarly building Haiku, Android, Minix, Hurd,Open (or Pure) Darwin, Haiku and OpenBSD.White paper:EnglishGermanT2 21.7 "Rebel Alliance"2021-07-08Today T2 SDE Linux 21.7 was released. An interim update to shipfull support for the new HiFive SiHive Unmatched 64-bit quad-core RISC-V 64board as well as a reference for the further refined smart optimizationsfor 32- and 64-bit x86. Of course all the other architectures, including: alpha,arm, arm64, hppa, ia64, m68k, mips64, mipsel, ppc, ppc64-32, ppc64le, riscv,riscv64, s390x, sparc64, superh, x86, and x86-64 can be rolling releaseupated thru the scripted build system.The 21.7 release received updates across the board, with latest Linuxkernel 5.13.1, as well as a major GCC 11 C++ templated ctor bug was fixed.There were 305 changesets and this is also the first release with ourAI bot "Data" contributing more revisions than human developers: Data: 164,humans: 141!Today the T2 System Development Environment Linux 21.5 wasreleased, with an even larger amount of supported, 18 pre- andcross-compiled set of architectures ever: alpha, arm, arm64, hppa,ia64, m68k, mips64, mipsel, ppc, ppc64-32, ppc64le, riscv, riscv64,s390x, sparc64, superh, x86, and x86-64.Major performance improemvnts were implemented, including: not yetupstream x86 concurrent TLB flushing, faster in-kernel zstd update aswell as smarter (profile guided Os vs O3) whole systemoptimizations!The 21.5 release received updates across the board, while a majorpoint of work was the GCC 11 update as well as re-basing and fixingupstream regressions for our Sony PS3 support as well as various smallimprovements, including an up to 15 seconds faster shutdown when usingsysvinit.Today the T2 Project released version 21.4, with the largest amount of pre- and cross-compiled set of architectures so far!A total of 15 architectures: x86-64, x86, arm64, arm, riscv64, riscv, ppc64le, ppc64-32, ppc sparc64, mips64, mipsel, hppa, m68k, alpha and ia64!As usually most packages are up-to-date, with 1294 change-sets, 1179 updates, and 120 fixes, including Linux 5.11.16, GCC 10.3, LLVM/Clang 12, as well as the latest version of Rust, X.org, Mesa, KDE and GNOME 40!After the first in a decade 20.10 release, 20.12 was alreadyreleased with all the last weeks improvements, including Sgi Octanesupport, improved network booting, and updated packages, includingthe Linux kernel and Mesa3d.A decade in the making, T2 version 20.10 was finally tagged andshipped! Grab your favorite release ISO, e.g. highly optimized AMD64,PPC64 for your PS3, MIPS64 for your Sgi Octane or any other of ourrelease builds for playing along at home!After an initial proof-of-concept around 2004, when T2 founder RenéRebe needed a Subversion client for at the time relatively new PowerPCMac OS X, now in the same situation again with Apple's ARM macOS "Big Sur"support for compiling and side-loading Open Source packages on other third-party systems using the vast anduniversal T2 package repository data is officially becomingmainline!Support for ARM64 wassignificantly improved and can be considered production quality.Initial and preleminary support was added to cross-compile Rust,and thus Firefox, e.g. for embeddedsystems like ARM, MIPS, or PowerPC desktops.Initial and preleminary support was added to cross-compile Rust,and thus Firefox, e.g. for embeddedsystems like ARM, MIPS, or PowerPC desktops.After being an early adopter of Link-Time-Ooptimizations when itwas initially implemented for GCC over a decade ago, support for LTOwas significantly improved to just work more often and moreextensively tested, too!With decades of support for alternative compilers and c libraries(uclibc, dietlibc, ...) support also added to support whole systembootstrap and builds using just LLVM/Clang and their run-time as wellas Musl libc.Initial support for the open-source RISC-Varchitecture was added to T2! Initial or preliminary, because upstreampackages do not include support for all bit-widths, such as 32 vs. 64-bit, andsome low-level packages do not yet have upstream support, such as strace andpackages of similar low-level nature.Support for the Hewlett-Packard Parallel/PrecisionArchitecture Reduced Instruction Set Compute was vastly improved in T2trunk. Now also directly providing an installableISO image, too!By switching the bit dated upstream source checksum to SHA-224the security of validating unmodified upstream sources is greatlyimproved.The T2 SDE web servieces are now also available with amuch shorter domain: t2sde.org!With switching to the new Zstandard compression we can greatlydecrease download bandwidth for you and our mirrors, as well asuncompression time of big packages during development.Support for the memory and cache optimizedx32 x86-64 ABI was added to the T2trunk. Allowig for higher performance embedded,desktop and server systems.Support for the upcoming 64-bit ARM desktop-and server-class performance CPUs was added to the T2 trunk.The first seven years of the T2 SDE where just the beginning: Welcometo revision 40k, and over 3270 packages ofwhich about 50% do cross compile.All of us wish you and your families a peaceful and recreative Christmas time.May it be a time of peace and reflection for all of you, whatever religion youbelieve in, whatever culture you are part of and wherever in the world you are.After years of development we are proud to announce the availabilityof the new T2 stable release 8.0.The 8.0 release received updates across the board, while a majorworking target was further improving cross compilation, and all officialISO images are now fully cross build!Over 10000 Subversion revisions indicate the magnitude of the release,with over 200 new packages, new features and various other improvementsand fixes.(more... - download...)May Day! 36200 revisions, 3219 packages, ~50% cross, 6 years2010-05-01We now have been working and polishing T2 for over 6 years! A massiveeffort to maintain all the different architectures -from ARM to x86,operating system support - from Linux towin32, packages - froma2ps to zziplib,and the cross compilation of it.The T2 SVN tree now contains more than 36000 versioned revisions, withover 3200 packages in tree, of which nearly50% do cross compile.The T2 team wishes you a happy public holiday! Enjoy!GCC 4.5 comes with new, excitingoptimizations and is now available in the T2 SDE SVN trunk.GCC 4.4 comes with new, excitingoptimizations and is now available in the T2 SDE SVN trunk.X11R7.5 approaching the final release, and so are the T2 X.orgpackages in the t2/trunkalready being updated.Support for non-Linux kernels for the T2 System Development Environment wason our agenda for quite a while, now. Lastweekend ExactCODE committed theinitial script adaptions and basic infrastructure. As a first stepT2 gained support to cross-compile MinGW(Win32) Windows executables.The first five years of the T2 SDE where just the beginning: Welcometo revision 33333, and over 3170 packages ofwhich nearly 50% do cross compile.The T2 SDE project team is proud to announce the 30000's T2 SVN sourcerepository revision, with over 3100 packages in the T2package repositories.

The series features u/dev, early user-space, fully modular kernel, X11R7,C++ cross compilation, powerpc64 and mips64 support as well as a whole lot ofupdates and refactoring under the hood. The x86 flavour already includessupport for latest Apple Macintosh Intel (Mactel) hardware and the associatedGrub fixes (A20 gate and keyboard).Thanks to the Linux New Media AG and theirOpenBooth,T2 is attending the worlds largest computer fair: CeBIT!The LinuxPark is located in hall 5, section F56.The first maintenance release (2.1.1) for the stable 2.1 branch was finalized.This release includes bug fixes, security fixes, updates and even someimprovement to the SDE. Most notable are: kaffe 1.1.6, kde 3.4.3, xfce 4.2.3.2,wine 0.9.1, mono 1.1.10, eclipse 3.1.1, xpdf 3.01pl1, koffice 1.4.2,samba 3.0.21a, OpenOffice.org (ooo) 2.0.0.1 and mplayer 1.0pre7try2.A vastly improved Emerge-Pkg script, improved dietlibc as well as improvedx86-64 and PowerPC64 support, target inheritance and autoextraction of .zipfiles was merged from the development trunk.Finally, with 2.2.0-epsilon the necessary installer rewrite was done to includesupport for u/dev. Additionally the 2.2 series includes a fully modular kernel,support for C++ cross compilation, powerpc64 and mips64 support as well as a wholelot of updates, including modular X.Org X11R7 and cleanups and refactoring underthe hood.Finally 2.1.0 was release with some bugfixes and minor (but important) updates,including: GCC 3.4.4, Abiword 2.2.11, Gnumeric 1.6.0, Samba 3.0.20b,and Apache 2.0.55.After the addition of the modular X.org - X11R7 - packages we are proudto announce to pass the 2000 packages mark with over 2100 (!!!)packages in the T2 package repositories!The modularized X.org release candidate X11R7 got packaged for T2.It is now the default X implementation in trunk and will be usedin the T2 2.2 release scheduled for November.This, hopefully last, release candidate includes general bugfixes and minor(but important) updates, most notably OpenOffice 1.9-m123, Mono 1.1.8.3,bdb 4.3.28, KDE 3.4.2 and Gnome 2.10.2.We are happy to announce the release of our second (and last?) candidatefor T2 2.1. The release includes major bugfix, and many harmless updateswhere most notable are: linux 2.6.11.12, glibc 2.3.5, OpenOffice 1.9-m104,wx 2.6.1.0, mono 1.1.8.2, XFCE 4.2.2, KDE 3.4.1 and Gnome 2.10.1.Of course the release ships with the latest stable release of KDE, GNOME,XFCE and Enlightenment 17.About 152 packages got updated, including Linux (2.4.31) and Linux (2.6.11.10)and 146 issues fixed. The release includes enhanced Java support, includingKaffee and Jikes. Automatic dependency and installed files detection wasimproved. Other package updates include Subversion (1.2.0), nvidia (1.0-7174)and Apache (2.0.54). Acroread (7.0) was added.With a lot of improvements over the first alpha version, the state of the artT2 live CD is coming along. An quiteimpressive amount of hardware has already beencertified to be able to run the CD without problems.Despite preparing the stable series for release, next generationwork is going on in the development trunk. Beside strong u/dev,D-BUS and HAL integration a really sophisticated as well as stateof the art T2 live CD is coming along. Visitthe project page for details and download link.After an enormous amount of updates and additions we released2.1.0-beta4 as last snapshot before the first release candidatewill be deployed in about one week.The release includes support for the SuperH CPU family,as well as enhanced AMD64 / x86-64 support, many improvementsfor cross compiling - including a new embedded target as solidbase for industrial products and support for squashfs andunionfs. Of course, the latest stable release of KDE (3.4.0), GNOME (2.10.0),XFCE (4.2.1) and Enlightenment 17 (2005-03-29).Setting up a CMS managed community website was on the todo since the beginningof T2. A work in progress site now upand running.After much last minute showstopper work in the 2.1.0-beta3 branch the treewas frozen and released, finally. The release includes: uclibc support (builds with far more packages thandietlibc!), parallel build support for make and scons, builds on x86-64,fixed ccache support to work reliable with recent ccache releases,improved sparc64 support, bash3 was fixed significantly, various bootdiskcreation and file layout improvements, wide ncurses added, the nvidia binaryonly driver really does get installed. The numerous package updates includelinux-2.6.10, linux-2.4.29 as well as migration to aspell-0.60 and developmenttools for Atmel AVR chips got included.Thanks to the Linux New Media AG and theirOpenBooth,T2 is attending the worlds largest computer fair: CeBIT!The LinuxPark is located in hall 6, section H18.The "T2" project tagged and released the internal milestone 2.1.0-beta2("Your own sweet way").The release includes more ROCK to T2 naming transitions, including therename of the internally used toolchain directory from ROCK toTOOLCHAIN, fixes for findutils, enhanced X.org radeon support(especially on PowerPC). The command wrapper code got a significantrestructuring so that ccache works more reliable now, as well asgeneral ccache fixes and basic distcc support. We now support markingdownload URLs as "no mirror". And the many updates include gtk+-2.6.0as well as freetype-2.1.7..The "T2" project tagged and released the internal milestone 2.1.0-beta("Today is gonna be the day").The release includes updates to linux26 (2.6.8.1 -> 2.6.9), linux24(2.4.28-pre4 -> 2.4.28),binutils (2.15.91.0.2 -> 2.15.92.0.2), gcc(3.4.2 -> 3.4.3), uclibc (0.9.26 -> 0.9.27-20041106), binutils(2.15.91.0.2 -> 2.15.94.0.1), KDE 3.3.2, Gnome 2.8.2 as well as manyother updates, fixes and improvements.The "T2" project tagged and released the internal milestone 2.1.0-alpha("Way to heaven").Major changes from ROCK Linux 2.0 and 2.1 include: gcc-3.4.x usedexclusively, a "sanitized" linux-header package which currently uses2.6.8.1 headers, X.Org is used exclusively, some packages got splitinto individual ones (e.g. alsa, mad, ogg-vorbis and xine), the .descD tag for the cvs:// URL scheme got revisited, the ugly date encodingvia a '!' fot dropped in favor of more natural form as to be executedmanually on the command line, the .desc NODIST "hack" support wasremoved, as well as the new CD tag not imported, the .desc tags CV-PATand CV-DEL support was dropped, many packages got updated and added,no people named repositories - most packages should now be sorted intocategory repositories - which so far scale quite well, no package fork/ package split stuff, no pseudo cross native compiler hacks and noperl cpan meta package fork whatever (tm) stuff, no default kernelstuff - a "sanitized" linux-header package is always used (always asup-to-date as possible - currently 2.6.8.1), no linux*-src packages -third party modules will be build as part of any kernel package (willbe implemented next week ;-)
