/tmp has to point to an actual filesystem with locking. 

     ----        a  tmp -> /dev/shmem

That not going to do it... You might be able to use TMPDIR to point at something on disk.

Subject: Re: SQLite3 on QNX Neutrino 6.x

Has there been any progress on this? I see that sqlite3 is now included in SDP 6.6, however, when I add it to the image,
 I also get this error:

# cd /tmp
# sqlite3 test.sqlite
SQLite version 3.7.14.1 2012-10-26 13:34:05
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> CREATE TABLE Cars(Id INTEGER PRIMARY KEY, Name TEXT, Price INTEGER);
Error: disk I/O error
sqlite>



This is the content of the image, because I might be missing a library:
