So I statically compile Sqlite3 version 3.8.7.2 into my DLL using /MT I use
#define SQLITE_THREADSAFE 1 #define HAVE_USLEEP 1 When I use my DLL it works perfectly fine? However... If I add a 3rd party LIB which also has Sqlite3 version 3.6.23.1 (I believe) statically linked into it (also using /MT) -- this library opens a database and writes to it while my DLL is running. While this is happening, I can open my database but I get an SQLITE_IOERR_ACCESS error returned if I call sqlite3_prepare_v2(). I have an error log callback which generates: sql = pragma table_info('mytablename'); Sqlite3 log: 3338 Err: os_win.c:37516: (0) winAccess(C:\MyAppPath\Databases\mydatabase.db-journal) - The operation completed successfully. Sqlite3 log: 3338 Err: disk I/O error The database I'm using is separate from the database running in the 3rd party lib. Anyone have any ideas on how to deal with the conflict? Thanks, Rail
