The resource source file is supposed to contain a version +# info section, that uses the string BUILDNUMBER as the least +# significant part of the version numbers. This script replaces that +# string with a "build number" before compiling the binary resource +# file. The build number is kept between builds in a "stamp" file, and +# incremented each time. (If there is no stamp file, build number 0 is +# used.) The intention is that only the "official" maintainer of a DLL +# keeps such a stamp file, and thus the DLLs he releases have +# increasing version number resources, which can be used by an +# installer program to decide whether to replace an existing DLL with +# the same name. + +# This is just my (tml@iki.fi) idea, if somebody comes up with a +# better way to generate version number resources, don't hesitate to +# suggest. + +# The command line arguments are: +# $1: the name of the .rc file to check +# $2: the name of the resource object file to produce, if the rc file exists + +# Check if we have a resource file for this DLL. +rcfile=$1 +resfile=$2 +if [ -f $rcfile ]; then + # Check if we have a build number stamp file. + basename=`basename $rcfile .rc` + if [ -f $basename-build.stamp ]; then + read number <$basename-build.stamp + buildnumber=$[number] + echo Build number $buildnumber + rm -rf $basename-build.stamp + else + echo Using zero as build number + buildnumber=0 + fi + + m4 -DBUILDNUMBER=$buildnumber <$rcfile >$$.rc && + ${WINDRES-windres} $$.rc $resfile && + rm $$.rc +else + # Return failure + exit 1 +fi |
