Hi there, ran into the same issue - Error: /usr/lib/x86_64-linux-gnu/sqlite/icu.so: undefined symbol: ucol_close_76
as ucol_close gets defined in /usr/include/unicode/ucol.h from https://packages.debian.org/trixie/libicu76-dev I installed that package (and libicu76 as well) and then tried recompiling the debian package while messing with CPATH/LDPATH - no success, will have to keep on using the sqlite with icu compiled in for the moment :/ since you probably can use ext-icu atm to compile other packages like in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=758985 the most straightforward testcase would be to open sqlite3 cli and try sqlite> .load /usr/lib/x86_64-linux-gnu/sqlite/icu or sqlite> SELECT load_extension('/usr/lib/x86_64-linux-gnu/sqlite/icu'); directly, both fail with "undefined symbol: ucol_close_76" here on up to date trixie thanks for the work on proper packaging the sqlite-icu extension! using sqlite to work with i18n user data is quite common on android, easily activating the same featureset on debian would really be nice. if I can assist in testing, please let me know Cheers, Jasper
