9Procedures for building ICU4J data from ICU4C data:
10
11*Setup*
12
13In the following,
14        $icu4c_root is the ICU4C root directory
15        $icu4j_root is the ICU4J root directory
16        $jdk_bin is the JDK bin directory (for the jar tool)
17
181. Download and build ICU4C. For more instructions on downloading and building
19        ICU4C, see the ICU4C readme at:
20        http://source.icu-project.org/repos/icu/icu/trunk/readme.html#HowToBuild
21	(Windows: build as x86, Release otherwise you will have to set 'CFG' differently below.)
22
23	*NOTE* You should do a full rebuild after any data changes.
241a.  If you didn't download from Subversion, you will also need the "icu4c-*-data.zip" file.  Unpack this file and replace the icu/source/data directory's contents with the contents of the data directory from the zip file.
25
26
272. Step 2 depends on whether you are on a Windows or a Unix-type
28platform.
29
30*Windows*
31
322a. On the command line, cd to $icu4c_root\source\data.
33
342b. On the command line,
35        nmake -f makedata.mak ICUMAKE=$icu4c_root\source\data\  CFG=x86\Release JAR="$jdk_bin\jar" ICU4J_ROOT=$icu4j_root  icu4j-data-install
36
37       Continue with step 3 below, in Java:
38
39
40*Linux*
41
42        $icu4c_build is the ICU4C root build directory,
43        which is $icu4c_root/source in an in-source build.
44        (in other words, $icu4c_build is where you ran runConfigureICU or configure)
45
462c. On the command line, cd to $icu4c_build/data
47
482d. Do
49        make JAR=$jdk_bin/jar ICU4J_ROOT=$icu4j_root icu4j-data-install
50
51       (You can omit the JAR if it's just jar.)
52
53	Continue with step 3, in Java:
54
55Step 2 on either platform will produce two files: icudata.jar and
56icutzdata.jar in $icu4j_root/main/shared/data.
57
58*Java*
59
603. After the ICU4C-side steps above, build the main target of the
61        ICU4J ant build to unpack the jar files with the following commands:
62
63        cd $icu4j_root
64        ant main
