beta2 compilation
Message 1 in thread
Moin moin,
I'm having a hard time compiling Qt Jambi beta2 here.
First of all compiling the generator failed in metainfogenerator.cpp,
line 336. There was
writeInitializationFunctionName(s, fileHash.key(f, ""), true);
which should be
writeInitializationFunctionName(s, fileHash.key(f), true);
But well, that was doable ;). Then, generator and all compiled, I moved
on with the main compilation and got

And now I'm lost, my cpp skillz are way to bad to find out how to fix
that, but I'm sure that there's someone who knows ;)

The QHash::key(const T &value, const Key &defaultValue) function used
here is actually a function introduced in Qt 4.3 which should be
available as a snapshot from Trolltech's web pages.
http://doc.trolltech.com/4.3/qhash.html#key-2
Note that there may be more issues related to building Jambi against an
earlier version of Qt.

Unfortunately, this is a bug for building on 64 bit Linux. A fix which
should work is to add a "(qint64)" cast in line 363 in
qtjambi/qtjambi_core.cpp. I've attached a patch to this mail.
Hope this helps! Let us know if there are further problems.

hehe, the check for 4.3 is there, although quite late ;).

So It really seems that I have to get a 4.3 snapshot installed, if there
only where 64bit binaries of jambi ;). Thanks for the help though.
