debhelper\-obsolete\-compat \- List of no longer supported compat levels
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
This document contains the upgrade guidelines from all compat levels
which are no longer supported.  Accordingly it is mostly for
historical purposes and to assist people upgrading from a
non-supported compat level to a supported level.
.PP
For upgrades from supported compat levels, please see \fBdebhelper\fR\|(7).
.SH "UPGRADE LIST FOR COMPAT LEVELS"
.IX Header "UPGRADE LIST FOR COMPAT LEVELS"
The following is the list of now obsolete compat levels and their
changes.
.IP "v1" 4
.IX Item "v1"
This is the original debhelper compatibility level, and so it is the default
one. In this mode, debhelper will use \fIdebian/tmp\fR as the package tree
directory for the first binary package listed in the control file, while using
debian/\fIpackage\fR for all other packages listed in the \fIcontrol\fR file.
.Sp
This mode is deprecated.
.IP "v2" 4
.IX Item "v2"
In this mode, debhelper will consistently use debian/\fIpackage\fR
as the package tree directory for every package that is built.
.Sp
This mode is deprecated.
.IP "v3" 4
.IX Item "v3"
This mode works like v2, with the following additions:
.RS 4
.IP "\-" 8
Debhelper config files support globbing via \fB*\fR and \fB?\fR, when appropriate. To
turn this off and use those characters raw, just prefix with a backslash.
.IP "\-" 8
\&\fBdh_makeshlibs\fR makes the \fIpostinst\fR and \fIpostrm\fR scripts call \fBldconfig\fR.
.IP "\-" 8
Every file in \fIetc/\fR is automatically flagged as a conffile by \fBdh_installdeb\fR.
.RE
.RS 4
.Sp
This mode is deprecated.
.RE
.IP "v4" 4
.IX Item "v4"
Changes from v3 are:
.RS 4
.IP "\-" 8
\&\fBdh_makeshlibs \-V\fR will not include the Debian part of the version number in
the generated dependency line in the shlibs file.
.IP "\-" 8
You are encouraged to put the new \fB${misc:Depends}\fR into \fIdebian/control\fR to
supplement the \fB${shlibs:Depends}\fR field.
.IP "\-" 8
\&\fBdh_fixperms\fR will make all files in \fIbin/\fR directories and in \fIetc/init.d\fR
executable.
.IP "\-" 8
\&\fBdh_link\fR will correct existing links to conform with policy.
.RE
.RS 4
.Sp
This mode is deprecated.
.RE
.IP "v5" 4
.IX Item "v5"
This is the lowest supported compatibility level.
.Sp
Changes from v4 are:
.RS 4
.IP "\-" 8
Comments are ignored in debhelper config files.
.IP "\-" 8
\&\fBdh_strip \-\-dbg\-package\fR now specifies the name of a package to put debugging
symbols in, not the packages to take the symbols from.
.IP "\-" 8
\&\fBdh_installdocs\fR skips installing empty files.
.IP "\-" 8
\&\fBdh_install\fR errors out if wildcards expand to nothing.
