Message-Id: <200503181418.j2IEI2TX019474@delorie.com> From: Andris Pavenis To: djgpp-announce AT delorie DOT com Subject: ANNOUNCE: Update of DJGPP port of GCC-3.3.5 Date: Fri, 18 Mar 2005 14:04:33 +0200 Content-Disposition: inline X-Virus-Scanned: by amavisd-new at fgi.fi X-MIME-Autoconverted: from quoted-printable to 8bit by delorie.com id j2IC4ZrL006046 Reply-To: djgpp AT delorie DOT com This is an announcement of an update of DJGPP port of gcc-3.3.5 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 http://gcc.gnu.org/gcc-3.3 for more detailed information about new features, fixed bugs and other changes in gcc-3.3.5 Currently C, C++, Fortran and Objective C compilers are supported for DJGPP. Java compiler is not ported and are not included. Ada compiler (as it itself is written in Ada) is able to bootstrap itself, but this is only test I have done. ===================================================================== NOTE: DWARF2 debugging info is now the default (when You specify GCC command line option, for example -g or -g3, ...). As result You need also new enough version of GDB for debugging: gdb611b.zip (or newer when available) from DJGPP distribution or recent build of RHIDE from http://rhide.sorceforge.net/snapshots. One can still use COFF (GCC command line option -gcoff) and stabs (command line options -gstabs, -gstabs+) for debugging. Also symify.exe from djdev203.zip works with COFF debugging info only. You need bfdsymify.exe instead (from gdb611b.zip) when DWARF2 or stabs debuging info is being used DJGPP binaries of GCC-3.3.5 are built and tested mostly under WinXP Pro (SP2).   ===================================================================== NOTE: You need last update of djdev203.zip with timestamp of August 2002 or later ('version: 2.03 patchlevel 2' in file manifest/djdev203.dsm) ===================================================================== Archives are available from DJGPP distribution     http://www.delorie.com/djgpp/getting.html in directory v2gnu: There are 11 archives:    gcc335.README - readme file from DJGPP port of GCC-3.3.5. It's                   in separate file to avoid need to download large archives                   to get this file.    gcc335s.zip  - sources of gcc-3.3.5. I put all sources in a single                   archive. This file is only needed if You're want to                   rebuild gcc-3.3.5 from sources.    gcc335b.zip  - binaries of C compiler    gpp335b.zip  - binaries of C++ compiler (needs gcc335b.zip)    g77335b.zip  - binaries of Fortran compiler (needs gcc335b.zip)    objc335b.zip - binaries of Objective C compiler (needs gcc335b.zip)    gcc335s2.zip - shell script and patches for original gcc-3.3.5.                   I used them to generate gcc-3.3.5 sources for DJGPP                   (gcc335s.zip).    ada335b.zip  - binaries of Ada compiler (warning: practically untested)    gcc335d.zip  - documentation of C compiler and libiberty (in DVI, PS, PDF     and HTML formats)    g77335d.zip  - documentation of GNU Fortran compiler    ada335d.zip  - documentation of Ada compiler (what can be generated from                   GCC sources). Files user need:    Programming languages  Needed files    C                      gcc335b.zip    C++                    gcc335b.zip, gpp335b.zip    Fortran                gcc335b.zip, g77335b.zip    Objective-C            gcc335b.zip, objc335b.zip    Ada                    ada335b.zip, gcc335b.zip For more information about this port see archive    gnu/gcc-3.35/readme.DJGPP after unpacking either gcc335b.zip or gcc335s.zip or get file gcc335.README from directory v2gnu in DJGPP distribution Also please DON'T mix C++ libraries (or object files) built with different compiler versions. C++ sources must be recompiled (seems that there is no need to do this for C sources). Object files generated by GCC-3.3.5 from C++ sources are incompatible with object files (or libraries) generated from C++ sources by any earlier GCC version System requirements =================== Latest update of DJGPP-2.03 (or above when available). Please verify whether You have a newest one. DJGPP-2.04 beta is also OK. binutils-2.13 or above (2.15 or above recommended). Perhaps binutils-2.11.2 or 2.12 could also be used but are not tested Some warning for users of C++. C++ compiler in gcc-3.3.5 does more strict syntax checking than earlier gcc versions before gcc-3.3. As result errors are generated in many places where earlier one got warnings. Note for users of C++ IO classes fstream, ifstream, ofstream ============================================================ There is a regression against GCC versions 2.95.3 and earlier: Member functions tellp(), tellg(), seekp() and seekg() are broken when stream is opened not in binary mode. If You are going to use any similar functions You must open stream in binary mode. Don't ask me when it will be fixed as I don't know that. I'm also not sure I'll spend much time trying to fix that.
