I'm trying to compile SQLite for the VxWorks 6.3 platform on an embedded target
(VxWorks in DKM rather than RTP) and have made fairly good progress but have
hit a brick wall.
I can get it to compile with the compile options listed below, however, when
run it gives "disk I/O error-SQLITE_IOERR_LOCK" (error code 0F0A).
The terminal console gives:
fcntl 0 38 SETLK RDLK 1073741824 1 0 -1
fcntl-failure-reason 0 38 SETLK RDLK 1073741824 1 0
The db file is created (and deleted when closed), but with zero contents. I
also do not see a journal file created at all even when journal mode is set to
"Persist".
I've tried changing the locking style (-SQLITE_ENABLE_LOCKING_STYLE) however
this gives me a shedload of compile errors for any value greater than "0" (see
below). SQLITE_NO_SYNC has no effect.
Any ideas?
=========================================
compiler options
-DSQLITE_OMIT_WAL=1 \
-DSQLITE_HOMEGROWN_RECURSIVE_MUTEX \
-DSQLITE_THREADSAFE=0 \
-DSQLITE_OMIT_LOAD_EXTENSION \
-DHAVE_UTIME \
-DSQLITE_LOCK_TRACE \
-DSQLITE_DEBUG=2 \
-DSQLITE_DEBUG_OS_TRACE=1
