Dear MacPort users, this is an Email to qt-interest due to problems of sqlite support in Qt4 using macPorts' sqlite3 port. See the end for macPorts-specific questions, please. On 05.01.2008, at 10:46, Dimitri wrote:

I am the MacPorts (www.macports.org) maintainer of Qt4 for Mac OS X.

I understand this MacPort is a binary package for MacOS made from a vanilla Qt/Mac source package. Is that correct?

Yes. However, we do (yet) not distribute binary packages but "recipes" to build them on the destination machine. When executed the qt4-mac Portfile (recipe) downloads the source from TrollTech and builds it..

By the way, you shouldn't have to force: -largefile -stl

You definitely shouldn't need: -no-nis -no-cups These are Qt/X11 only.

Okay, but thet should not hurd, I guess.

We are having some problems with sqlite support when using the system-sqlite (sqlite 3.5.4), i.e., calls to sqlite3_set_auxdata fail (confirmed, for example, for sqliteman and the books demo of Qt4). [...] Starting the books demo gives the following backtrace: [...] Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x000000000000003d Crashed Thread: 0 Thread 0 Crashed: 0 libsqlite3.0.dylib 0x95f0a56e sqlite3_set_auxdata + 6062 1 libsqlite3.0.dylib 0x95f380b2 sqlite3RegisterBuiltinFunctions + 178 2 libsqlite3.0.dylib 0x010d2f41 openDatabase + 961 3 libsqlite3.0.dylib 0x010d3033 sqlite3_open16 + 131 4 libqsqlite.dylib 0x010a6124 [...]

This could as well be an issue with SQLite. It would be interesting to see how the system SQLite library itself has been built.

It's build using this Portfile http://trac.macports.org/projects/macports/browser/trunk/dports/databases/sq...

What are the arguments passed to sqlite3_open16? It would be worth writing a non-Qt program and passing the same arguments to sqlite3_open16. Does it also crash?

For the books example this should be the call from within Qt's bool QSQLiteDriver::open(const QString & db, const QString &, const QString &, const QString &, int, const QString &conOpts) which is this: if (sqlite3_open16(db.constData(), &d->access) == SQLITE_OK) { We get there from books.app QSqlError initDb() which contains QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE"); ... MacPorts question: Are people successfully using MacPorts' sqlite3 port? Are you using the functions in question? sqlite3_open16 sqlite3_set_auxdata Are there any known issues with these functions on Mac OS X or in MacPorts?
