     17 # This script is used to transform the dependency files generated by GCC
     18 # For example, a typical .d file will have a line like:
     19 #
     20 #    source.o: /full/path/to/source.c other.h headers.h
     21 #    ...
     22 #
     23 # the script is used to replace 'source.o' to a full path, as in
     24 #
     25 #    objs/intermediates/emulator/source.o: /full/path/to/source.c other.h headers.h
     26 #
     27 # parameters
     28 #
     29 # $1: object file (full path)
     30 # $2: source dependency file to modify (erased on success)
     31 # $3: target source dependency file
     32 #
     33 
     34 # quote the object path. we change a single '.' into
     35 # a '\.' since this will be parsed by sed.
     36 #
     37 OBJECT=`echo $1 | sed -e s/\\\\./\\\\\\\\./g`
     38 #echo OBJECT=$OBJECT
     39 
     40 OBJ_NAME=`basename $OBJECT`
     41 #echo OBJ_NAME=$OBJ_NAME
     42 
     43 # we replace $OBJ_NAME with $OBJECT only if $OBJ_NAME starts the line
     44 # that's because some versions of GCC (e.g. 4.2.3) already produce
     45 # a correct dependency line with the full path to the object file.
     46 # In this case, we don't want to touch anything
     47 #
     48 cat $2 | sed -e s%^$OBJ_NAME%$OBJECT%g > $3 && rm -f $2
