ANNOUNCE: DJGPP port of GCC-4.7.0

[Andris Pavenis]

This is announcement of DJGPP port of GCC-4.7.0

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.


Warning: DJGPP port of binutils-2.17 or newer is required.
It is however recommended to use binutils-2.22
or newer when using DJGPP port of gcc-4.7.0.

Use of DJGPP port of binutils-2.22 or newer is required for building
gcc-4.7.0 for DJGPP.

=======================================
Build for current stable version of DJGPP (djdev203 patchlevel 2) is
available from:
ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/
and mirror sites (see http://www.delorie.com/djgpp/getting.html)

(it is identical with file gnu/gcc-4.70/readme.DJGPP in archives
gcc470b.zip and gcc470s.zip)


Binaries are built and tested mostly under Windows Vista Business (SP2)
========================================
Build for development version of DJGPP (CVS version of djdev204) is
available from
ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/

ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/gfor470b.zip
ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/gcc470b.zip
ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/gpp470b.zip
ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/objc470b.zip

Binaries for djdev204 may not work with djdev203r2 (at least
C++ compiler).

Binaries for djdev203 may probably work also with djdev204 CVS
versions, but also such use is not recommended.


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

I myself have tested binary RPMs on
- CentOS 5.8 ix86 (really in chroot under Fedora 16 x86_64)
- Fedora 16 x86_64 only
They are built under CentOS 5.8, and linked statically with GMP-5.0.2,
MPFR-3.1.0 and MPC-0.9 to avoid unnecessary dependencies and increase
compatibility with other Linux distributions. For example they are
expected to work without problems in recent Fedora versions
(both i686 and x86_64)

gcc470s2.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 gcc470s.zip is a side product of building
gcc-4.7.0 Linux to DJGPP cross-compiler RPM packages. See source
RPM for patches applied to original FSF version of GCC-4.7.0.

=========================================

See
http://gcc.gnu.org/gcc-4.6
for more information about GCC-4.7.0 and about changes in comparison
with earlier versions

Also see file gnu/gcc-4.70/readme.DJGPP (from gcc470b.zip and
gcc470s.zip) or
ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/gcc470.README for more
information about this port.

There is also my web page about DJGPP port of GCC

http://www.iki.fi/andris.pavenis/djgpp/gcc

I cannot promise however, that I'll update it very often.
However new versions may appear there earlier (including ones not available
from ftp://ftp.delorie.com).

Hi,
is there some difference from gcc version 4.7.0 that I found on your
site, binary compile date 17.4.2012 ?

First of all, big thanks for your efforts!

What happened here? What went wrong? I don't expect any miracles here,
esp. with no upstream help, but this can't be good, can it? :-(

The only "obvious" change I can find is this, and surely that didn't
break it??

Ada:
The command-line option -feliminate-unused-debug-types has been re-
enabled by default, as it is for the other languages, leading to a
reduction in debug info size of 12.5% and more for relevant cases, as
well as to a small compilation speedup.

Or this page, even. ;-)

Which will ... never mind, forgot I already accidentally checked the
ZIP Picker, it already has 4.7.0 offered. Wouldn't 4.6.3 be a safer
choice since Ada isn't available? (Though admittedly that's less
interesting to most C/C++ people.) Ah, well, I guess it doesn't matter
(and I never learned Ada, sadly, only subsets of other Wirth-ian
languages).

At least one of Ada tools (gnatmake if I remember correctly) failed to build for DJGPP. I wrote "at
least one" as I do not know whether there would be more problems later. Fixing this problem would
require noticeably more knowledge about Ada language that I have. This problem does not appear for
cross-compiler so there is no need to leave Ada out when building cross-compiler RPMs.

Well: replacements 's/4.6.3/4.7.0/g', 's/4.63/4.70/g' and 's/463/470/g' were done and still one
forgotten. Of course there were other changes as well as one can see. I did not however write
announcement from scratch.
