Thank you, Dan! I've applied your patch and attempted to build the shell tool with lsm and lz4 support built-in. I've tried a couple of variations on build commands. (I've consulted [https://www.sqlite.org/howtocompile.html](https://www.sqlite.org/howtocompile.html) and the READMEs in the autoconf dir.) In each case, however, I've gotten this error: ``` Undefined symbols for architecture x86_64: "_sqlite3_lsm_init", referenced from: _openDatabase in sqlite3.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [libsqlite3.la] Error 1 ``` Do you have any more tips for replicating your build? I'm developing on MacOS 10.15.6. I could easily try a new clone of sqlite3, or a build on ubuntu, where the app we're prototyping is most likely to run. Thank you again!
