# uname -a FreeBSD port-master 12.1-RELEASE-p2 FreeBSD 12.1-RELEASE-p2 r357991 GENERIC amd64 /etc/make.conf is an empty file A scan of ports/UPDATING for sqlite didn't have anything that seemed related. when building sqlite3 on system above the last several lines related to the build are: libtool: link: cc -DSQLITE_ENABLE_FTS4 -DSQLITE_ENABLE_FTS5 -DSQLITE_ENABLE_RTREE -DSQLITE_HAVE_ZLIB -DSQLITE_ENABLE_EXPLAIN_COMMENTS -DSQLITE_ENABLE_DBPAGE_VTAB -DSQLITE_ENABLE_STMTVTAB -DSQLITE_ENABLE_DBSTAT_VTAB -O2 -pipe -fstack-protector-strong -fno-strict-aliasing -fstack-protector-strong -o sqlite3 sqlite3-shell.o sqlite3-sqlite3.o -L/usr/local/lib -lreadline -ltermcap -lz -lm ld: error: undefined symbol: pthread_create >>> referenced by sqlite3.c >>> sqlite3-sqlite3.o:(vdbeSorterFlushPMA) ld: error: undefined symbol: pthread_create >>> referenced by sqlite3.c >>> sqlite3-sqlite3.o:(vdbePmaReaderIncrInit) ld: error: undefined symbol: pthread_create >>> referenced by sqlite3.c >>> sqlite3-sqlite3.o:(vdbePmaReaderNext) cc: error: linker command failed with exit code 1 (use -v to see invocation) *** Error code 1 Seems like there are two relatively obvious options: 1. Remove THREADS from the OPTIONS_DEFINE in the Makefile 2. Add an appropriate #ifdef or similar around the threaded code. Alas, I don't have enough experience at the moment to implement this and send a suggested patch.
Encountered the same issue, FreeBSD 12.2-RELEASE r366954 GENERIC AMD. I'm installing this on a single threaded VPS, so had unchecked []THREADS and building databases/sqlite3, which results in a failed build as Brian Haug described. Building WITH [*]THREADS builds successfully.
