The build is broken: /Users/andersca/src/webkit/WebCore/kwq/KWQTextCodec.mm:33:25: unicode/ucnv.h: No such file or directory looks like adding ucnv.h to WebCore/icu/unicode should do the trick
Created attachment 2919 [details] adds icu/unicode/ucnv.h to fix broken build.
Created attachment 2920 [details] Adds ucnv_err.h as well.
My apologies. I forgot that these headers are not included on all systems and that we accommodate everyone by adding headers to WebCore/icu/unicode. Lesson learned.
