All Rights Reserved. 3The genren.pl script is used to generate source/common/unicode/urename.h header file, which is needed for renaming the ICU exported names. 4 5This script is intended to be used on Linux, although it should work on any platform that has Perl and nm command. Makefile may need to be updated, it's not 100% portable. 6 7It also does not currently work well in an out-of-source situation. 8 9The following instructions are for Linux version. 10- urename.h file should be generated after implementation is complete for a release. 11- the version number for a release should be set according to the list in source/common/unicode/uvernum.h 12 13Before generating urename.h, the layout engine header files must be installed from the harfbuzz project. 14This is prerequisite for the icu layoutex (Paragraph Layout) project, which is subject to renaming. 15(Using the svn command is the simplest way of getting just the files from one subdirectory of the git project.) 16 17 cd icu4c/source 18 svn export https://github.com/behdad/icu-le-hb/trunk/src layout 19 20- Regenerate urename.h 21 22 cd icu4c/source/tools/genren 23 make install-header 24 25- urename.h will be updated in icu/source/common/unicode/urename.h **in your original source directory** 26- Warnings concerning bad namespace (not 'icu') on UCaseMap can be ignored. 27- Eyeball the new file for errors 28 29 cd icu4c/source 30 svn diff common/unicode/urename.h 31 32- Other make targets here 33 34 clean - cleans out intermediate files 35 urename.h -just builds ./urename.h 36
