Re: [sqlite] Core dumps on AIX with optimization
If you are using the verson of Sqlite in one big file you are expecting a lot from the optimizer. I would never compile Sqlite that way, instead do it the normal way and link the optimized. code. Also make sure you remove the -g option which interferes with some AIX linking. My experience with IBM's Xlc is that it has a very aggressive optimizer and will produce optimized code of high quality, running on one of my tests 40% better than gcc code. I would not compile large files with it.

Re: [sqlite] Core dumps on AIX with optimization
I use sqlite on AIX, but compile using gcc. Can you try the gcc compiler instead? --- On Fri, 9/19/08, Ribeiro, Glauber <[EMAIL PROTECTED]> wrote: From: Ribeiro, Glauber <[EMAIL PROTECTED]> Subject: [sqlite] Core dumps on AIX with optimization To: "General Discussion of SQLite Database" <sqlite-users@sqlite.org> Date: Friday, September 19, 2008, 11:55 AM Just wondering, are there other AIX Sqlite users out there, and what have you done in order to get a successful compile?

Re: [sqlite] Core dumps on AIX with optimization
We use Sqlite on AIX and discovered that when compiling with gcc we have to remove the debug -g from the makefiles No optimization issues. We always link statically.
