Download and build ICU4C. For more instructions on downloading and building ICU4C, see the ICU4C readme at: http://source.icu-project.org/repos/icu/icu/tags/release-3-8/readme.html#HowToBuild 2. In your shell, navigate to $icu4c_root/source/tools/genrb. $icu4c_root is the root directory of ICU4C source package. 3. Create a new file named "Makefile.local" in this directory. In this file set the ICU4J_HOME variable to be the root path of ICU4J. Ex: ICU4J_HOME=/home/srl/icu4j 4. If there are spaces in your Java bin directory path (which is especially common using cygwin) (EX: /cygdrive/c/Program Files/Java/jdk1.5.0_15/bin), you may need to set GENDTJAR_JARHOME in Makefile.local. On a standard Unix based system, with the Java bin directory in your PATH, this step is not required. You can set GENDTJAR_JARHOME by hard coding the path to the Java bin directory. For example, on Cygwinc (notice the backslash used for the space): GENDTJAR_JARHOME=/cygdrive/c/Program\ Files/Java/jdk1.5.0_15/bin 5. In this same directory $icu4c_root/source/tools/genrb, run the command 'make build-icu4j' 6. Build the resources target of the ICU4J ant build to unpack the jar files with the following commands: cd $icu4j_root ant resources ******************************************************************************** If the above procedure fails to work, you may attempt to use the old procedure which uses less automation & path "guessing": 1. Download and build ICU4C. For more instructions on downloading and building ICU4C, see the ICU4C readme at: http://source.icu-project.org/repos/icu/icu/tags/release-3-8/readme.html#HowToBuild 2. Change directory to $icu4c_root/source/tools/genrb. $icu4c_root is the root directory of ICU4C source package. 3. Run gendtjar.pl from that directory itself with the command: ./gendtjar.pl --icu-root=$icu4c_root --jar=$jdk_home/bin --icu4j-root=$icu4j_root e.g. ./gendtjar.pl --icu-root=$HOME/icu4c --jar=/usr/local/bin/java/bin/ --icu4j-root=$HOME/icu4j Execution of gendtjar.pl script will create the required jar files in $icu4c_root/source/tools/genrb/temp and then copy them to their final locations in the ICU4J structure: $icu4j_root/src/com/ibm/icu/impl/data and $icu4j_root/src/com/ibm/icu/dev/data. 4. Build resources target of ant to unpack the jar files with the following commands: cd $icu4j_root ant resources Note: if gendtjar.pl does not work, the --verbose option can help in debugging why it went wrong. ********************************************************************************
