### autogen.sh - tool to help build Emacs from a bzr checkout

## This file is part of GNU Emacs.
## The Emacs bzr repository does not include the configure script
## (and associated helpers). The first time you fetch Emacs from bzr,
## run this script to generate the necessary files.
-## For more details, see the file INSTALL.BZR.
+## For more details, see the file INSTALL.REPO.
### Code:
## Tools we need:
## Note that we respect the values of AUTOCONF etc, like autoreconf does.
-progs="autoconf automake"
+progs="autoconf automake pkg-config"
## Minimum versions we need:
-autoconf_min=`sed -n 's/^ *AC_PREREQ(\([0-9\.]*\)).*/\1/p' configure.in`
+autoconf_min=`sed -n 's/^ *AC_PREREQ(\([0-9\.]*\)).*/\1/p' configure.ac`
-## FIXME how to determine this from the sources?
-automake_min=1.11
+## This will need improving if more options are ever added to the
+## AM_INIT_AUTOMAKE call.
+automake_min=`sed -n 's/^ *AM_INIT_AUTOMAKE(\([0-9\.]*\)).*/\1/p' configure.ac`
+pkg_config_min=`sed -n 's/^ *PKG_PROG_PKG_CONFIG(\([0-9\.]*\)).*/\1/p' configure.ac`
## $1 = program, eg "autoconf".
## Echo the version string, eg "2.59".
get_version ()
{
## Remove eg "./autogen.sh: line 50: autoconf: command not found".
- $1 --version 2>&1 | sed -e '/not found/d' -n -e '1 s/.* \([1-9][0-9\.]*\).*/\1/p'

}
## $1 = version string, eg "2.59"
## $1 = program
## $2 = minimum version.
-## Return 0 if program is present with version >= minumum version.
+## Return 0 if program is present with version >= minimum version.
## Return 1 if program is missing.
## Return 2 if program is present but too old.
## Return 3 for unexpected error (eg failed to parse version).

If you know that the required versions are in your PATH, but this
script has made an error, then you can simply run
-autoreconf -i -I m4
+autoreconf -fi -I m4
instead of this script.
-If all else fails, you can try using the pre-built versions of the
-generated files by doing:
-
-./autogen/copy_autogen
-
-This is not recommended - see the comments in \`copy_autogen'.
-
Please report any problems with this script to bug-gnu-emacs@gnu.org .
