QtJambiAwtBridge problem - pre-built for Windows?
Message 1 in thread
This is a follow-up to an earlier technical support effort:
I am a former Qt/C++ developer now trying to use the (pre-built)
evaluation version of Qt Jambi for Windows to put together a demo of
using Qt Jambi as part of an existing large Java-based development
effort. I have the Qt Jambi evaluation download running successfully
within our environment, but to make the demo useful I need to be able to
embed some Qt widgets within Swing/Awt containers so I was interested in
trying out the QtJambiAwtBridge. However, since I do not currently have
a Qt/C++ development environment (only Java), I requested and received a
pre-compiled version of the bridge. Unfortunately I cannot get it to
successfully load the native qawt.dll library despite all my environment
configuration efforts, and I only get UnsatisfiedLink errors even though
the library is located at referenced paths (actually in the same
directory as QtCore4.dll and jawt.dll which do load successfully).
Running the QtInAwt example using the -Dcom.trolltech.qt.verbose-loading
option, provides the output listed below. My assumption at this point
is that the qawt.dll library was not compiled in a way that is
compatible with how the Qt Jambi evaluation version I downloaded was
compiled. Can anyone provide any assistance here, or provide me a
pre-compiled version of qawt.dll for Windows that is compatible with the
Qt Jambi evaluation download?
Thank you. Any help is much appreciated!

Hi, John!
That may be the case, as we recently switched to using Microsoft Visual
Studio 2005 for the binary packages.
We'll put compatible binary versions of the QtJambiAwtBridge out on
labs.trolltech.com sometime next week so people won't have this problem.
I'll send a brief reminder to the list when this happens.

Hi,
I've created binaries for win32 for use with commercial/evaluation and
opensource. They are located in the subfolders
- prebuilt/win32-commercial-4.3.3_01 for commercial and eval
- prebuilt/win32-gpl-4.3.3_01 for open source.
Please note that these versions are tied strictly to the licenced
editions and the version of Qt Jambi so these will only work for the
current release.
best regards,
Gunnar

Thanks Gunnar!
Are the subfolders for these prebuilt QtJambiAwtBridge win32 binaries
subversion subfolders, or somewhere on a trolltech web/FTP site? I've
never used subversion before, but I assume I can just install a Windows
subversion folder and do something like:
svn://labs.trolltech.com/svn/qtjambi/qtjambiawtbridge/prebuilt/win32-com
mercial-4.3.3_01
I'll look forward to trying out the bridge and will hopefully be able to
provide you some useful feedback.

It should be enough to check out the toplevel folder:
svn co svn://labs.trolltech.com/svn/qtjambi/qtjambiawtbridge
The subdirectories will be included in the checkout.
