I cannot add a new file to the VOB. I tried both UI context menu on windows as well as cleartool command line utility.
cleartool> checkout .
Checkout comm
As mentioned in this thread (and already commented):
You'll need a rule that selects
/main/0
or/main/LATEST
/main/0
is the placeholder version created for any new element added to source control.
See for instance "how to create a branch in ClearCase" or "How best to branch in Clearcase?" for an example of a config spec allowing to add to source control in a branch.
element * CHECKEDOUT
element * .../aBranch/LATEST
element * STARTING_LABEL -mkbranch aBranch
# selection rule for new "added to source control" file
element * /main/0 -mkbranch aBranch
element * /main/LATEST
