Subject:	ANNOUNCE: DJGPP port of GCC-12.1.0
Reply-To:	djgpp AT delorie DOT com

This is announcement of an update of DJGPP port of GCC-12.1.0

GCC used to stand for the GNU C Compiler, but since the
compiler supports several other languages aside from C,
it now stands for the GNU Compiler Collection.

See
     https://gcc.gnu.org/pipermail/gcc-announce/2022/000171.html
for original announcement of gcc-12.1.0 release

************************************************************
*                     CHANGES                              *
************************************************************

- no Ada compiler built for DJGPP (neither is cross-compiler from Linux).
   Ada libraries build fails for DJGPP target and I do not know language
   well enough to try to fix it (I suspect that it may even be not possible
   without changes in other DJGPP tools)
- I dropped last 0 from version number (it is expected to always be 0 for
   release versions anyway), to get it 8+3 filename friendly

************************************************************
*                     WARNINGS                             *
************************************************************
- This GCC port is for DJGPP v2.05
   Build for DJGPP 2.03p2 is not and will not be available.

- DJGPP port of binutils-2.30 or newer is required.
   Older binutils version do not work with gcc-12.1.0. Newer
   version like 2.34 recommended.

************************************************************

Build for current stable version of DJGPP (djdev205) is
available from
     https://www.delorie.com/pub/djgpp/current/v2gnu/
and mirror sites (see https://www.delorie.com/djgpp/getting.html)

Binaries are built and tested in Windows Vista Business SP3 bit. Unfortunately Microsoft has broken 
DPMI
in Windows 10 32 bit since March 2018. There is also no improvement in recent Insider builds of 32 bit
versions of Windows 10.


Source RPMS needed for building Linux to DJGPP cross-compiler
=============================================================

Binary RPMs for both i686 and x86_64 are available. I built these binary RPMs
in CentOS 7 chroot under ArchLinux. Binaries are linked with GMP-6.2.1
MPFR-4.1.0 and MPC-1.2.1 (statical linking has been used to avoid unnecessary
dependencies and increase compatibility with other Linux distributions. For example
they are expected to work without problems in other reasonably recent RPM based Linux
distributions (like Fedora, RHEL-7 and newer, etc)

Additionally support for ArchLinux are available from AUR (aur.archlinux.org):
     https://aur.archlinux.org/packages/djgpp-gcc/

gcc121s2.zip is no more provided as patching GCC using DJGPP tools
has not been tested and even attempted by me for a long time.
DJGPP source file gcc121s.zip is a side product of building
gcc-10.2.0 Linux to DJGPP cross-compiler RPM packages. See source
RPM for patches applied to original FSF version of GCC-10.2.0.

Cross-compiler SRPM:

https://www.delorie.com/pub/djgpp/rpms/djcross-gcc-12.1.0/djcross-gcc-12.1.0-1ap.src.rpm

Cross-compiler binary RPMs (built under CentOS 6.9 i386, are expected to work on other
recent enough RPM based Linux distributions.

     GNU C compiler:
https://www.delorie.com/pub/djgpp/rpms/djcross-gcc-12.1.0/djcross-gcc-12.1.0-1ap.x86_64.rpm

     GNU C++ compiler:
https://www.delorie.com/pub/djgpp/rpms/djcross-gcc-12.1.0/djcross-gcc-c++-12.1.0-1ap.x86_64.rpm

     GNU Fortran compiler:
https://www.delorie.com/pub/djgpp/rpms/djcross-gcc-12.1.0/djcross-gcc-gfortran-12.1.0-1ap.x86_64.rpm

     GNU Objective C and Objective C++ compilers:
https://www.delorie.com/pub/djgpp/rpms/djcross-gcc-12.1.0/djcross-gcc-objc-12.1.0-1ap.x86_64.rpm

     Tools for GCC 12.1.0 (currently only fixincl, most users do not need this):
https://www.delorie.com/pub/djgpp/rpms/djcross-gcc-12.1.0/djcross-gcc-tools-12.1.0-1ap.x86_64.rpm

     Info files of GCC-12.1.0 (a separate RPM file as these files are expected to
     conflict with system compiler info files, but You do not need to install them...):
https://www.delorie.com/pub/djgpp/rpms/djcross-gcc-12.1.0/djcross-gcc-info-12.1.0-1ap.x86_64.rpm

Binary RPMs for i686 are no more provided. One should be able to build them from SRPM though

You need also cross binutils (choose required binary RPM file or build from SRPM)
https://www.delorie.com/pub/djgpp/rpms/djcross-binutils-2.30.1-1ap.src.rpm
https://www.delorie.com/pub/djgpp/rpms/djcross-binutils-2.30.1-1ap.x86_64.rpm

You need also DJGPP development libraries, include files and some tools (eg. stubify)
https://www.delorie.com/pub/djgpp/rpms/djcrx-2.05-5.x86_64.rpm
      https://www.delorie.com/pub/djgpp/rpms/djcrx-2.05-5.src.rpm
Note that one can use
https://www.delorie.com/pub/djgpp/rpms/djcrx-bootstrap-2.05-1.src.rpm
      for bootstrapping

for more information about GCC-12.1.0 and about changes in comparison
with earlier versions

Also see file gnu/gcc-12.10/readme.DJGPP (from gcc121b.zip and
gcc121s.zip) for more information about this port. I have not changed it, except of automatic
editing of version numbers and URLs - sorry
