The script I intend to use to obtain package information is in the
GraphicsMagick repository and produces information gleaned from a
'version.sh' script which has the smarts to produce some obvious
variable names.
echo `./scripts/pkginfo.sh package_bugreport`
graphicsmagick-bugs@xxxxxxxxxxxxxxxxxxxxx
% echo `./scripts/pkginfo.sh package_name`
GraphicsMagick
% echo `./scripts/pkginfo.sh package_version`
1.4.020120814
It is intended to be used like this in configure.ac:
AC_INIT(m4_esyscmd([scripts/pkginfo.sh package_name]),
m4_esyscmd([scripts/pkginfo.sh package_version]),
m4_esyscmd([scripts/pkginfo.sh package_bugreport]))
Unfortunately, the values passed to AC_INIT are cached so even if the
configure script is run again, it uses the cached values rather than
the new values.
The script:
#!/bin/sh
#
# Print the package version based on content of $srcdir/version.sh.
#
# This script is expected to be run under the context of a configure
# script (via AC_INIT) to dynamically determine the package version.
me=$0
info=$1
srcdir=`dirname $0`/..
value=
nl='
'
. version.sh
case "${info}" in
package_bugreport )
value="${PACKAGE_BUGREPORT}"
;;
package_name )
value="${PACKAGE_NAME}"
;;
package_version )
value="${PACKAGE_VERSION}${PACKAGE_VERSION_ADDENDUM}"
;;
* )
echo "$me: Must supply argument {package_bugreport, package_name, package_version}"
exit 1
;;
esac
# Omit the trailing newline, so that m4_esyscmd can use the result directly.
echo "${value}" | tr -d "$nl"
