Message-Id: <200305131704.h4DH4vL19116@delorie.com> From: Andris Pavenis To: djgpp-announce AT delorie DOT com Subject: ANNOUNCE: DJGPP port of GCC-3.2.3 Date: Tue, 13 May 2003 20:06:00 +0300 Content-Disposition: inline Reply-To: djgpp AT delorie DOT com This is an announcement of DJGPP port of gcc-3.2.3 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-3.2/changes.html for more detailed information about new features and other changes in gcc-3.2.3 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: I have changed to use DWARF2 debugging info by default (when You specify GCC command line option -g or -g3, ...). DWARF2 debugging info was already available for DJGPP since GCC-3.0, but was not the default. As result You need also new version of GDB for debugging: gdb53b.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 gdb53b.zip) when DWARF2 or stabs debuging info is being used ===================================================================== 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 in Simtelnet (and mirror sites) in directory v2gnu: There are 6 archives: gcc323.README - readme file from DJGPP port of GCC-3.2.3. It's in separate file to avoid need to download large archives to get this file. gcc323s.zip - sources of gcc-3.2.3. I put all sources in a single archive. This file is only needed if You're want to rebuild gcc-3.2.3 from sources. gcc323b.zip - binaries of C compiler gpp323b.zip - binaries of C++ compiler (needs gcc323b.zip) g77323b.zip - binaries of Fortran compiler (needs gcc323b.zip) objc323b.zip - binaries of Objective C compiler (needs gcc323b.zip) gcc323s2.zip - shell script and patches for original gcc-3.2.3. I used them to generate gcc-3.2.3 sources for DJGPP (gcc323s.zip). ada323b.zip - binaries of Ada compiler (warning: practically untested) gcc323d.zip - GCC documentation in DVI, PS, PDF and HTML format Files user need: Programming languages Needed files C gcc323b.zip C++ gcc323b.zip, gpp323b.zip Fortran gcc323b.zip, g77323b.zip Objective-C gcc323b.zip, objc323b.zip Ada ada323b.zip, gcc323b.zip NOTE: gcc323b.zip contains file cxxfilt.exe and there is file with same name in binutils (for example bnu213b.zip). You can safely overwrite the old one. For more information about this port see archive gnu/gcc-3.23/readme.DJGPP after unpacking either gcc322b.zip or gcc323s.zip or get file gcc323.README from directory v2gnu in DJGPP distribution Also please DON'T mix C++ libraries (or object files) built with different compiler versions. C++ sources should be recompiled (seems that there is no need to do this for C sources). Object files generated by GCC-3.2.3 from C++ sources are incompatible with object files (or libraries) generated from C++ sources by any earlier GCC version before GCC-3.2. So all C++ sources must be recompiled after upgrade to GCC-3.2.3 from earlier compiler version. Please don't use prebuilt binaries of DJGPP v2.04 Alpha 1 (this version only!) with this GCC version as they are built using GCC-3.2.2. If You like to use DJGPP v2.04 Alpha 1, then it's recommended to rebuild it from sources. System requirements =================== Latest update of DJGPP-2.03 (or above when available). Please verify whether You have a newest one. binutils-2.13 or above. It's no more possible to use binutils-2.8.1 or 2.9.1. Command line option -mno-bnu210 is no more supported. 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-3.2.3 does more strict syntax checking than gcc and egcs versions older than gcc-3.1. 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 should 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. Send suggestions and bug reports concerning the DJGPP port of GCC to comp.os.msdos.djgpp or . Happy hacking Andris Pavenis
