+ICU only uses the tzdataYYYYV.tar.gz files,
where YYYY is the year and V is the version letter ('a'...'z').
+This directory has partial contents of tzcode checked into ICU
+
----------------------------------------------------------------------
HOWTO
-1. Obtain the current versions of tzcodeYYYYV.tar.gz (aka `tzcode')
- and tzdataYYYYV.tar.gz (aka `tzdata') from the FTP site given
+0. Note, these instructions will only work on POSIX type systems.
+
+1. Obtain the current versions of tzdataYYYYV.tar.gz (aka `tzdata') from the FTP site given
above. Either manually download or use wget:
$ cd {path_to}/icu/source/tools/tzcode
- $ wget "ftp://elsie.nci.nih.gov/pub/tz*.tar.gz"
+ $ wget "ftp://elsie.nci.nih.gov/pub/tzdata*.tar.gz"
-2. Unpack tzcode and tzdata directly into the directory tzcode:
-
- $ tar xzvf tzcode*.tar.gz
- $ tar xzvf tzdata*.tar.gz
+2. copy only one tzdata*.tar.gz file into the icu/source/data/in/ directory (you may have to create this directory)
*** Make sure you only have ONE FILE named tzdata*.tar.gz in the
directory.
- *** Do NOT delete the tzdata*.tar.gz file.
-
- The Makefile looks in the current directory to determine the
- version of Olson data it is building by looking for tzdata*.tar.gz.
-
-3. Apply the ICU patch to zic.c:
-
- $ patch < patch-icu-tzcode
-
- If patch complains at this point, there is a mismatch that must be
- manually addressed. See the CVS log of `patch-icu-tzcode' for
- version details.
-
-4. Build:
-
- $ make icu_data
-
-5. Copy the data files to the correct location in the ICU4C/ICU4J
- source trees:
-
- $ cp zoneinfo.txt ../../../data/misc/
- $ cp ZoneMetaData.java {path_to}/icu4j/src/com/ibm/icu/impl
-
-6. Rebuild ICU:
- $ cd ../../../
- $ {*make}
+3. Build ICU normally. You will see a notice "updating zoneinfo.txt..."
-7. Don't forget to check in the new zoneinfo.txt (from its location at
+4. For ICU maintainers, don't forget to check in the new
+ zoneinfo.txt (from its location at
{path_to}/icu/source/data/misc/zoneinfo.txt) into CVS.

-HOWTO regenerate patch-icu-tzcode
-
-If you need to edit any of the tzcode* files, you will need to
-regenerate the patch file as follows.
-
-1. Follow the above instructions to extract and patch the tzcode*
- files in {path_to}/icu/source/tools/tzcode. Modify any of the
- tzcode files.
-
-2. Extract a clean set of the tzcode* files into a new directory,
- ../tzcode.orig/:
-
- $ mkdir ../tzcode.orig
- $ cd ../tzcode.orig
- $ tar xzf ../tzcode/tzcode*.tar.gz
- $ cd ../tzcode
-
-3. Compute diffs, ignoring files that are in only one directory:
-
- $ diff -ur ../tzcode.orig . | grep -vE -e "^Only in " > patch-icu-tzcode
-
-4. Test the patch-icu-tzcode file by regenerating and diffing the
- files again in another directory. The expected output from the
- final diff command is *nothing*.
-
- $ mkdir ../tzcode.new
- $ cd ../tzcode.new
- $ tar xzf ../tzcode/tzcode*.tar.gz
- $ patch < ../tzcode/patch-icu-tzcode
- $ cd ../tzcode
- $ diff -ur ../tzcode.new . | grep -vE -e "^Only in "
-
-5. Check in the new patch-icu-tzcode file.
