Source code

Since GDB's development process is iterative (continuous incremental change) current development sources can be considered stable and are available.

However, if you would like to try a version of gdb drawn from the most recent release branch, they are also available.

• Read-only CVS:

  Before your first access of the CVS repository you will need to login. Use the command:

  cvs -d :pserver:anoncvs@sources.redhat.com:/cvs/src login
  {enter "anoncvs" as the password}
  

  A weekly snapshot (gdb+dejagnu-CVS-YYYYMMDD.tar.bz2) of the sources checked out using CVS is available for download from the current snapshot directory. Since the archive is compressed using bzip2 it is the fastest and most efficient way of obtaining a read-only source tree under CVS.

  Once you have downloaded and unpacked this snapshot, you can cd to the src directory and use the command:

  cvs update
  

  to bring your sources up-to-date (see note above about login). Note though that new directories should not be checked out using cvs update -d (that will check out the entire repository), instead each new directory should e checked out individually using cvs update -d DIRECTORY.

  Alternativly, you can check out a copy of the CVS repository directly using the command:

  cvs -d :pserver:anoncvs@sources.redhat.com:/cvs/src co gdb+dejagnu
  

  Slow internet connection? Use cvs -z COMPRESSION-LEVEL -d .... The -z COMPRESSION-LEVEL causes CVS to compress files with gzip before transfering them. The option can either be specified on the command line or added to your ~/.cvsrc file.

  See the CVS home page for further information.

• Read-write CVS (GDB deveopers only):

  If you already have a read-only copy of CVS on hand then there is no need to re-check out a source tree. Instead a shell script like the below can be used to create a read-rewite source tree from a read-only tree:

  #!/bin/sh -ex
  if test $# -ne 3
  then
    echo Usage: $0 source dest youraccount
  fi
  src=$1 ; shift
  dst=$1 ; shift
  acc=$1 ; shift
  
  # Copy the CVS repository to the new home
  ( cd `dirname ${src}` && tar cf - `basename ${src}` ) \
    | ( cd ${dst} && tar xpf - )
  
  # Convert the copied CVS repository to read/write
  cd ${dst}
  find `basename ${src}` -name 'Root' -print | while read root
  do
    echo ":ext:${acc}@sources.redhat.com:/cvs/src" > $root
  done
  

  Alternatively, to check out a new read-write copy of the repository, use a command sequence like:

  CVS_RSH=ssh ; export CVS_RSH
  cvs -d :ext:YOURACCOUNT@sources.redhat.com:/cvs/src co gdb+dejagnu
  

• FTP:

  A daily snapshot of the current development sources (current subdirectory) and most recent release branch (branch subdirectory) are available from:

  ftp://sources.redhat.com/pub/gdb/snapshots/
  

  These snapshots are mirrored so it will pay to check for a more local site.

  Differences between daily snapshots are also available.

• WWW:

  Browse the CVS repository via the web using the CVSweb interface.
