# This scripts create Makefile dependencies out of class files. It |
||||
# simply scans the constant pool of the class files, finding all |
||||
# references to other classes and adding a dependency to that class. |
||||
# |
||||
# It doesn't do a perfect job, since it can't handle dependencies to |
||||
# constant values in different classes: The compiler inlines the |
||||
# constant and thus doesn't include a reference to the class. |
||||
# |
||||
# Usage: |
||||
# javaDependencies.pl -classpath <cp> [-dependdir <depdir> [-subdir <subdir>]] |
||||
# [-depfile <depfile>] |
||||
# <classfiles> |
||||
# |
||||
# cp: colon separated paths to the java files we should depend on. |
||||
# depdir: if set, use this path as path to the java files when printing |
||||
# dependencies, not the path where the java files were found. |
||||
# useful, if you want to make use of VPATH settings in Makefile. |
||||
# subdir: if set, this is the path from depdir to the current directory. |
||||
# Use it to remove unneccessary ../../$subdir/ |
||||
# depfile: the name of the dependency file, default is "Makefile.dep". |
||||
# class: The class files (not inner classes) for which the dependencies |
||||
# should be generated. We will also look for inner and anon |
||||
# classes. |
