Re: [icu-support] rematch.cpp : undefined reference to `utext_next32_44'

[Steven R. L. <sr...@ic...>]

The header urename.h redefines all symbols (by default) to have the 
version number attached.

Can you run  "nm" on your .o file vs. the ICU library (libicuuc.a etc) ? 
also could there be an ICU in /usr/include || /usr/lib which is being 
picked up instead?
