[Ffmpeg-devel] Problem building from snapshots

[Sibnath GHOSH]

I have the following line in version.sh. From which file is the Revision
read.

svn_revision=`cd "$1" && LC_ALL=C svn info 2> /dev/null | grep Revision |
cut -d' ' -f2`
test $svn_revision || svn_revision=`cd "$1" && grep revision .svn/entries |
\
                                    cut -d '"' -f2 2> /dev/null`
test $svn_revision || svn_revision=UNKNOWN
NEW_REVISION="#define FFMPEG_VERSION \"SVN-r$svn_revision\""
OLD_REVISION=`cat version.h 2> /dev/null`

Regards
sibnath

Ummmmm, no ...


cerebus:/tmp/ffmpeg-export-2007-04-19$ cat version.sh #!/bin/sh

NEW_REVISION="#define FFMPEG_VERSION \"SVN-r8757\""
OLD_REVISION=`cat version.h 2> /dev/null`

# Update version.h only on revision changes to avoid spurious rebuilds if
test "$NEW_REVISION" != "$OLD_REVISION"; then
    echo "$NEW_REVISION" > version.h
fi


There is no way this script can result in rUNKNOWN.  You must be using a
different snapshot.
