Hi.

You must copy IKVM.OpenJDK.Core.dll next to your exe, and also add it
as a reference to your project. Same for the rest of the dlls as
described on the qt4dotnet homepage.

For more info see this email of mine (the devs don't seem to be
around, so they haven't updated/clarified the homepage):
http://groups.google.com/group/qt4dotnet/msg/91c4f1e355a5c5bd

Hi Stefan,

i keep getting same errors .

I did put ALL the Dll/s in the exe folder.

Could you describe to me , which steps you took to get output ?

NOTE :  the compiles are ok, without errors , so only at runtime the dlls are not foud,

Pete

Hi, make sure you are using the DLLs that correspond to your ARCH (32
bits vs 64 bits) if you have a 64 bit machine and if you use the 32bit
DLLs make sure you compile your application as an "x86" binary and not
as an "Any CPU" binary (in the Properties->Build->Platform Target
section), the later will try to find 64 bit version dlls in a 64 bit
version machine.

Thanks,

David.

[peter bax]

Hi david,

was already set to x86 , but still the same.

here is a screenshot

[peter bax]

Hi ,

hope you can point me to right direction, have spent few days now, tried also to copy all dlls to exe directory, but so far no result,

You should have all the Qt jambi DLLs:

com_trolltech_qt_core.dll
com_trolltech_qt_gui.dll, etc.(the ones that have this pattern:
com_trolltech_qt_*.dll)

Make sure you copied those DLLs from the Qt Jambi 4.6.3 folder that
you should have downloaded from here:

http://sourceforge.net/projects/qtjambi/files/

I think those files are under the LIB folder.

Also you have to make sure you have the qtjambi.dll found in the same
place (so you will have a qtjambi.dll and a qtjambi-4.6.3.dll, the
later comes from the qt4dotnet project). You also have to copy the Qt
shared libraries (i.e. QtCore4.dll, QtGui4.dll etc) and finally make
sure you have the correct ikvm-native.dll there too. (the one that is
found in the qtjambi-4.6.3.zip file in the qt4dotnet project.

To test first put all these DLLs next to your executable. And let me
know if that works.

I hope that helps.

Thanks,

David.

Hello Pete,

 

one thing you can do is to install dependencywalker (32 bit) from: http://www.dependencywalker.com/ and run it on the native dll's in the folder. it will let you know which dependency cannot be fulfulled.

 

best
Frank

Hi David,

have almost all but : 

dowloaded again the qt4dotnet ( 64mb) , byt there is no qtjambi-4.6.3.zip in this ,

"the one that is
found in the qtjambi-4.6.3.zip file in the qt4dotnet projec"

could you point me to the right file ?

( also where are the Shared files from qt located ? ??) 

thanks, Pete

[David Canar]

This is the qtjambi-4.6.3.zip :
http://code.google.com/p/qt4dotnet/downloads/detail?name=qtjambi-4.6.3.zip

The Shared libs for Qt are located under: qtjambi-4.6.3\bin folder of
the QtJambi library, The QtJambi libs are located under
qtjambi-4.6.3\lib

Thanks,

David.

[peter bax]

Hi david,

think i got all of it now, see screenshot,

but still same runtime error

Pete

[David Canar]

You also need to reference these assemblies from your project:

IKVM.OpenJDK.Core.dll
IKVM.Runtime.dll
IKVM.Runtime.JNI.dll

Referencing those will copy a bunch other IKVM.*.dll files in your application.

These are found in the qtjambi-4.6.3.zip that I mentioned before. I
think those are the last ones you are missing

Thanks,

David.

[peter bax]

Hello Frank,

here ist he outhput from the dep. walker,

thanks, Pete

[peter bax]

Hi david,

these are referenced now,

have all dlls in the project now. 

but runtime error is : cannot find qtcore4.dll

see below:

thanks, Pete

Hello Pete ...

 

that diealog shows that there is no error with the ikvm-native.dll ... you want to continue that for the remaining files. Especially the key files like qtjambi.dll

[peter bax]

Hello Frank,

ok ! 

apparently the msvcm80.dll's ( but all 3 of them ?)  were also necessary , when the dep walker tested on qtjambi.dll ,

the demo app is running now ! 

many thanks  !!!
