Rebuilding's ICU's .dat file

[Jeffrey Blattman]

Android 8.1.

I need to re-build ICU's icudt58l.dat file because someone decided that Canada should really have a 24 hour clock. I did this on an Android 5.1 source tree by making changes to the locales/... file I needed, then doing a "make" in icu4c/source/data. When I do this on our Android 8.1 tree, the build go fine, but when I plop the .dat file on the device it won't boot and gets this,

I also tried re-building with zero changes to any source files and had the same problem. The resulting .dat file is ~3k smaller that the one in stubdata.

Any ideas?

I got the same issue wth my Android 8.1 source. In my case, because in the icudt58l.dat has no ubidi.icu file, MissingResourceException is thrown.

In the Makefile, ubidi.icu is included by UNI_CORE_DATA and only is built ifneq ($(INCLUDE_UNI_CORE_DATA),).

That is, you have to include INCLUDE_UNI_CORE_DATA in the make command.

make INCLUDE_UNI_CORE_DATA=1

And Here is all the commands that I use:

cd external/icu/icu4c

mkdir build

cd build

../source/runConfigureICU Linux --with-data-packaging=archive

# work around if there is no xlocale.h file in your environment
sudo ln -s /usr/include/locale.h /usr/include/xlocale.h

make INCLUDE_UNI_CORE_DATA=1

adb root; adb remount; adb push ./data/out/icudt58l.dat system/usr/icu/icudt58l.dat

adb shell stop; adb shell start

Have you found the solution yet? I got the same issue with Android 8.1.

cd external/icu/icu4c

mkdir build

cd build

../source/configure

# work around because there is no xlocale.h

sudo ln -s /usr/include/locale.h /usr/include/xlocale.h

make -j16

adb push ./data/out/tmp/icudt58l.dat system/usr/icu/icudt58l.dat

adb reboot
