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
- Note: if you have trouble with null output, put xalan.jar and xercesImpl.jar from <http://xalan.apache.org/xalan-j/downloads.html#latest-release> into ./lib/
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/trunk/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).
