Minimal ICU data file for RoboVM

This is a modified version of ICU 51.2's data sources (icu4c-51_2-data) which builds a minimal icudt51l.dat file for use as default ICU data in RoboVM. With this data file en is the only available locale and any attempt to format dates and numbers using some other locale will fallback on the en locale's formatting rules. No break iterators and no collations are included.

Build instructions

curl -O http://download.icu-project.org/files/icu4c/51.2/icu4c-51_2-src.tgz
tar xvfz icu4c-51_2-src.tgz
cd icu/source
rm -rf data
git clone git://github.com/robovm/icu4c-51_2-data.git data
./runConfigureICU MacOSX --with-data-packaging=archive
make
make

Note: For me the first make fails with an error. Rerunning make works.

The icudt51l.dat will be saved to out/icudt51l.dat

Generate the header file for embedding in RoboVM

RoboVM embeds a gzipped version of the data file as code. Here's how to generate the header file for inclusion in RoboVM:

gzip --best -c out/icudt51l.dat > out/icudt51l.dat.gz
xxd -i out/icudt51l.dat.gz > out/icudt51l.dat.gz.h
LEN=`stat -f '%z' out/icudt51l.dat`; echo "unsigned int out_icudt51l_dat_len = $LEN;" >> out/icudt51l.dat.gz.h
