Error code 26 is SQLITE_NOTADB. That only happens when SQLite is reading the 100-byte header at the beginning of the database file and finds that header is correct. This is given a discinct error code because usually that finding means that you are trying to open something that is not really an SQLite database file. Debugging hints: (1) Set error logging on your application: https://www.sqlite.org/errlog.html (2) Compile the "showdb" utility program (using "make showdb") and then run "showdb DATABASE dbheader" on a corrupt database file. Send the results to this list. (There are many other useful run-time options for "showdb" that you might also find useful.) > > > This connection is in “multi thread” mode I think (compiled with thread > safety on but opened with NO_MUTEX). Does the problem go away if you se the threading mode to "serialized"? -- D.
