Even when fixed known typo in Makefile.PL, still fails on qt4.5, see log below. Guess: Likely the autogenerated XS fails due to new symbols introduced into qt. Maintainer might update these. <STEPS> $ sudo cpan cpan $ install QtCore cpan $ look QtCore <THEN> As mentioned in the qt-apps.org forum root@quicksilver:~/.cpan/build/QtCore-4.004-TOJY4B# diff Makefile.PL Makefile.PL~ 31c31 < $QtCore_path = $args{-qc}; ---

Hey, Not really much to do. One can get this running: three issue's needed to be fixed. See below to get compiled, but without preserving its function for anything that uses somehow QMutex or QThread. Sorry, but just made dumb strip-off's to see how much would be needed): See: root@quicksilver:~/.cpan/build/QtCore-4.004-TOJY4B# ls *~ Makefile.PL~ QAbstractFileEngine.xs~ QFSFileEngine.xs~ QMutex.xs~ QThread.xs~ (1) Stripped functions using "ExtensionOption" class from QAbstractFileEngine.xs QFSFileEngine.xs (2) QMutex.xs: QMutexLocker() constructor no longer available, use QMutexLocker( Mutex *). Likely again an qt4.5 api change: See: http://doc.trolltech.com/4.5/qmutexlocker.html (3) QThread.xs: stripped complains about private methods. XS class decleration superficially looks right, but still subtle declaration flaws may be present. * XS's "THIS" macro repeatedly error'd as beeing unknown (likely secondary gcc complain because upstream code is not legible for compiler) Please review and fix: needs minor qt knowledge and minor XS knowledge. Anybody ? Lets go, muenalan <STEP> Stripped error'd function: *::extension(...) from files: QAbstractFileEngine.xs (see below) QFSFileEngine.xs <Example: After manual strip-off> root@quicksilver:~/.cpan/build/QtCore-4.004-TOJY4B# diff QAbstractFileEngine.xs QAbstractFileEngine.xs~ 240a241,280

Cool, But did you ever thought of using: http://qt.gitorious.org/qt-labs/qtscriptgenerator/trees/master/generator instead of your modules approach ? You mentioned something in your TODO list about getting qtgl etc running, but with this it should be easier. It might be easy to get *all* qt packages binding for perl with this... PS: Why you made the QtCore etc ? You work with Qt often ? Just curious. Thx, Murat 2009/10/18 Vadim Likhota (Vadim Likhota) via RT <bug-QtCore@rt.cpan.org>:

curious. I writed program separately on C++ using Qt4 and separately on Perl. For internal corporative programs interpreter is better then compiler.

It is also small. The qtscript generator actually has solved this by selecting at runtime which plugins/shared objects/qt modules you want. Just say use qtcore.so, qtgui.so, qtweb.so and go etc. It is fast and modular. Just a suggestion. Consider: paid people maintain it at trolltech/nokia now because the qtscript/ecma interpreter depends on it.

Its really impressive how much more productive it is with perl ! I use it now and its just impressive (except the stupid workarround bugs). Thanks again for you great work ! Murat
