# This script is used when compiling Classpath with gcj. The idea is
|
|
# to compile one package at a time, and only recompile packages when
|
|
# actually required.
|
|
|
|
# We build java->class by package so we need to know what .java files
|
|
# correspond to what package.
|
|
|
|
# We have a .stamp file for each package; this is the makefile target.
|
|
# We also have a .list file for each package, which lists all the
|
|
# input files in that package.
|
|
|
|
# gen-classlist.sh makes a list of all the .java files we are going to compile.
|
|
|
|
# This script generates Makefile.deps, which looks like this:
|
|
#
|
|
# java/awt/AWTUtilities.class: lists/java-awt.stamp
|
|
# lists/java-awt.list: /home/aph/gcc/gcc/libjava/classpath/gnu/java/awt/AWTUtilities.java
|
|
# java/awt/BitMaskExtent.class: lists/java-awt.stamp
|
|
# lists/java-awt.list: /home/aph/gcc/gcc/libjava/classpath/gnu/java/awt/BitMaskExtent.java
|
|
# java/awt/BitwiseXORComposite.class: lists/java-awt.stamp
|
|
# lists/java-awt.list: /home/aph/gcc/gcc/libjava/classpath/gnu/java/awt/BitwiseXORComposite.java
|
|
|
|
# This uses a somewhat hacky procedure for finding the package of a
|
|
# given file.
