Subject [jira] Commented: (LUCENE-2629) In modules/analysys/icu, ant gennorm2 does not work
Date Tue, 31 Aug 2010 01:01:53 GMT


Robert Muir commented on LUCENE-2629:

bq. I find it a strange concept to have two binary file formats, one for big-endian and one
for little-endian, only one of which is usable. I would have thought that the gennorm2 program
should generate the file format that works, no matter what machine it is run on.

I could be wrong, but I think the reason ICU's data files are endian-dependent is because
they are designed to be very very quickly mapped into memory
(e.g. the speed at which the underlying character property data can be mapped into memory
so that java.lang.Character becomes useful is sensitive)

convert the binary file to big-endian.
