ANNOUNCE: DJGPP port of GCC-4.7.2

[Andris Pavenis]

This is announcement of DJGPP port of GCC-4.7.2

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-2.19 or newer is required.
It is however recommended to use binutils-2.22
or newer

Use of DJGPP port of binutils-2.22 or newer is required for building
gcc-4.7.2 for DJGPP.

The bug that caused several last versions of GCC to crash when
DJGPP environment variable was not defined is now fixed. This version
reports in this case error message about DJGPP installation error.

=======================================
Build for current stable version of DJGPP (djdev203 patchlevel 2) is
available from:
ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/

(it is identical with file gnu/gcc-4.72/readme.DJGPP in archives
gcc472b.zip and gcc472s.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/ada472b.zip
ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/gfor472b.zip
ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/gcc472b.zip
ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/gpp472b.zip
ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/objc472b.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 17 x86_64)
- Fedora 17 x86_64 only
They are built under CentOS 5.8, and linked statically with GMP-5.0.5,
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)

gcc472s2.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 gcc472s.zip is a side product of building
gcc-4.7.2 Linux to DJGPP cross-compiler RPM packages. See source
RPM for patches applied to original FSF version of GCC-4.7.2.
You can find the same contents in the file

You need also DJGPP development libraries, include files and some tools (eg. stubify)

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

See
http://gcc.gnu.org/gcc-4.7
for more information about GCC-4.7.2 and about changes in comparison
with earlier versions

Also see file gnu/gcc-4.72/readme.DJGPP (from gcc472b.zip and
gcc472s.zip) or
ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/gcc472.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,
First and foremost, thanks again for your efforts.

Sorry that I'm a week late in testing this. Anyways, it still has the same SFN-only tempfile problem (via gnatmake when compiling Gautier's ENG3D018.ZIP) previously reported (June 20: "gcc-4.7.x and native Ada compiler for DJGPP"). IIRC, you had fixed it here below, but I guess you never integrated the same change for this newer compile:

http://ap1.pp.fi/djgpp/gcc/4.7.1/v204/testonly/ada471b.zip

Apparently it tries to write to GNAT-TEMP-000001.TMP and somehow gets confused if LFNs aren't available.

"It seems that we need to have own version of gcc/ada/s-os_lib.adb
with modified temporary file name generation for DJGPP. "

P.S. I thought "1 filename conflict" could be avoided by removing / renaming the "GARLIC" version of that file (s-stratt-xdr.adb) since we don't need or use it, but it's your decision, I suppose.
