The ICU extension (as in icu.c) does not contain the tokenizer ... it only contains the extension functions ... (upper / lower / etc)
Looking in the amalgamation it appears that the icu tokenizer module is defined in fts3_icu.c I have no idea how you load a tokenizer module as part of a loadable extension, or even if that is supported at all (or specifically in the case of icu). Generally speaking I think you just compile the amalgamation (or the full source tree) with SQLITE_ENABLE_ICU defined to use icu. --- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume. >-----Original Message----- >From: sqlite-users [mailto:sqlite-users- >boun...@mailinglists.sqlite.org] On Behalf Of ?? >Sent: Thursday, 18 October, 2018 02:56 >To: SQLite mailing list >Subject: Re: [sqlite] Error: dlsym(0x7fa073e02c60, >sqlite3_sqliteicu_init): symbol not found > >Hi, > >Thanks for your reply.
