The contents of the JAR I build (qtjambi-win32-msvc2010-4.8.3.jar)
contains the following DLLs:
* com_trolltech_qt_XYZ.dll, where XYZ is the name of the subsystem
(i.e. core, gui,...), and without the '1' suffix.
* qtjambi.dll
* the necessary DLLs from Qt itself.
When I start my application with this JAR out-of-the-box, I do get
these messages:
Loading library: 'qtjambi1.dll'...
So, these DLLs don't exist. I get the impression wants to load the
wrong DLLs.
To be quite clear in how I experience it right now:
*Scenario 1:* clean Qt-Jambi build, no local modifications done.
In this scenario the main issue is that the loading process cannot
find the dlls with the '1' suffix, which is obvious, since they don't
exist.
*Scenario 2:* same as scenario 1, but now some DLLs copied with the
'1' suffix
In this scenario the startup fails to load some of the Qt-Jambi DLLs
with the message that it cannot find dependent libraries.
*Scenario 3:* same as scenario 2, but now the qtjambi.dll and Qt own
DLLs are moved to the PATH (i.e. the same folder as where the
application starts).
In this scenario the loading goes OK, but we now get a JVM crash
*Scenario 4:* same as scenario 3, but now with all DLLs in the working
directory.
I hope this clarifies a bit the process I've gone through and explains
the different problems I've experienced.
I've been doing some further investigations on this and I managed to get
rid of the "1" suffix while loading, and as a consequence the JVM crash
also went away (don't know how it was related though).
The source patch I've done is attached. I'm not completely sure if this
is a safe patch, but at least it seems to resolve the issues I face on
Windows.
Currently doing some further testings & checks.
Kind regards,
Kenny
