I would add a printf statement in unixDelete rather than rely on a break point working.
Of course, it may not be unixDelete that is the problem, we just need to be sure. Do you have a disk on your target system? If you do, perhaps you could try creating the database file on that and see if that works.

I do not know why. You are right! What OS your host system is running (Windows in my case). I want to get some information from the unixdelete funtion.

On my vxWorks system, if I open a new database and create a table it always calls unixDelete trying to delete a “database name”-wal file. This doesn’t exist so it has to handle the error. This patch that was added …. #if OS_VXWORKS }else if( errno==0x380003 ){ /* == S_dosFsLib_FILE_NOT_FOUND */ rc = SQLITE_IOERR_DELETE_NOENT; #endif to handle the error code returned by a dosFs filing system. Before adding this patch I got the disk I/O error. Because you are using the host filing system I would guess the error code returned will be something different. Looking at the WindRiver documentation for the tsfs driver it says…. “The routines in this library return the VxWorks error codes that most closely match the errnos generated by the corresponding host function.” So it looks like it will depend on what OS your host system is running (Windows I assume in your case).

So it will need another check adding to unixDelete Regards Andy Ling From: 王庆刚 [mailto:2004wqg2...@163.com] Sent: 28 August 2014 15:01 To: Andy Ling Cc: sqlite-users@sqlite.org; Jan Nijtmans Subject: Re:RE: Re:RE: [sqlite] HELP sqlite3 used in vxworks has someproblem？ Is unixUnlink an function?
