emacs-snapshot build for debian

The followings are how I build emacs-snapshot for debian by myself. My PC is debian unstable.

get tar ball

> git clone --depth 1 git://git.sv.gnu.org/emacs.git

(check if make works well.)
> ./autogen.sh
> ./configure
> make bootstrap
(make the tar ball.)
> make clean
> tar cjvf emacs-snapshot-20150126.tar.bz2 ./emacs

prepare for package build

> apt-get source emacs-snapshot
> cd emacs-snapshot-20140823
> uupdate -v 20150126 ../emacs-snapshot-20150126.tar.bz2

correct patches

The following patches are not applicable as 20140823. So I modified the files by myself.

• 0002-Run-debian-startup-and-set-debian-emacs-flavor.patch
• 0003-Adjust-documentation-references-for-Debian.patch
• 0009-Some-documentation-references-to-usr-local-have-been.patch

After I correct the files, I made patches as followings:

> git diff --no-prefix a/lisp/startup.el b/lisp/startup.el > 0002-Run-debian-startup-and-set-debian-emacs-flavor.patch
> git diff --no-prefix a/etc/NEWS b/etc/NEWS > 0003-Adjust-documentation-references-for-Debian.patch
> git diff --no-prefix a/doc/man/emacs.1.in b/doc/man/emacs.1.in > 0009-Some-documentation-references-to-usr-local-have-been.patch

For convenience, I show these patches below:

I copied these patches to debian/patches in the emacs snapshot directory.

edit control file

The package libgnutls-dev is no longer available, thus I modified to libgnutls28-dev.

edit emacs-snapshot-bin-common.overrides.lintian and other lintian, postinst files

Accroding to Changelog, there is no longer grep-changelog, so I removed the lines of grep-changelog in the followings:

• emacs-snapshot-bin-common.overrides.lintian
• emacs-snapshot-bin-common.postinst
• emacs-bin-common.overrides.lintian
• emacs-bin-common.postinst

That’s it. Good luck.
