Hi Joao,

It looks like one of your stacks incorrectly depends on the stack trunk.
The script below should help you find the problem stack.

Tully


{{{
#!/usr/bin/bash

STACKS=`rosstack list-names`

for STACK in $STACKS
do
    DEPS=`rosstack depends1 $STACK`
    for D in $DEPS
      do
        if [ 'trunk' = $D ] ; then
            echo $STACK
            echo "depends on"
            echo $D
            echo ""
        fi
      done
done
}}}
