# Copyright (C) 2009-2011 IBM and Others. All Rights Reserved API Change Report: A tool to generate a report of API status changes between two ICU4C releases. (ICU4J has a builtin change report generator) Requirements: - Everything needed to build ICU4C from a command line (UNIX) environment - Doxygen (for generating docs). Doxygen 1.7.5.1 is recommended for ICU API docs, but an older Doxygen may work for the API Change Report. - Java JDK 1.5+ - Apache Ant To use the utility: 1. Put both old and new ICU source trees on your system 2. Run "configure" in both old and new (you can use any mixture of in-source and out-of-source builds). Doxygen must be found during the configure phase, but you do not need to build the standard API docs. 3. create a Makefile.local in this readme's directory (tools/release/java/) with just these two lines: OLD_ICU=/xsrl/E/icu-1.0 NEW_ICU=/xsrl/E/icu-6.8 ( where these are the paths to the parent of 'source', etc) If your ICU is an out-of-source-build, add these two lines indicating the build location: OLD_ICU_BUILD=/xsrl/E/icu-build-m48 NEW_ICU_BUILD=/xsrl/E/icu-build 4. from this directory, (tools/release/java/) run Make to build docs: make 5. This will create an 'APIChangeReport.html' file in this directory. Look it over, and then check it in to ${NEW_ICU}/APIChangeReport.html (parent of icu/source).
