Better do next:
install -D $SVNROOT/yoper/projects/rpmlookup/Default.cfg
~/.yoperbuild/rpmlookup/Default.cfg
so you won't have to create any leading dirs. I also think that the cache
should be set by default at
~.yoperbuild/rpmlookup/cache, see below.
However, I don't get it to work:
[EMAIL PROTECTED] ~/svn/yoper/projects/rpmlookup $ ./svnCacheLookup.py -d bison
usage ./svnCacheLookup.py -rd packagename
-r := calculate reverse depencies
-d := calculate depencies
[EMAIL PROTECTED] ~/svn/yoper/projects/rpmlookup $ ./svnCacheLookup.py -r bison
usage ./svnCacheLookup.py -rd packagename
-r := calculate reverse depencies
-d := calculate depencies
[EMAIL PROTECTED] ~/svn/yoper/projects/rpmlookup $ cat
~/.yoperbuild/rpmlookup/Default.cfg
[Default]
cache = /home/musikolo/.yoperbuild/rpmlookup/cache
svndir = /home/musikolo/svn/yoper
[EMAIL PROTECTED] ~/svn/yoper/projects/rpmlookup $ ls -l
~/.yoperbuild/rpmlookup/
total 4
-rw-r--r-- 1 musikolo users 0 2007-12-23 13:15 cache
-rwxr-xr-x 1 musikolo users 92 2007-12-23 13:13 Default.cfg
[EMAIL PROTECTED] ~/svn/yoper/projects/rpmlookup $
Is there any thing I have done wrongly?
Is there any reason why Default.cfg needs execution permissions? If it isn't,
it should be revoked.
Said this, thanks a million for this tool. I hope we all often use it and don't
have any more broken packages for quite long time...
Best regards! ;-)
