Problems using generator
Message 1 in thread
Hello,
I'm trying to upgrade my generated qt native widget, but I'm getting these:

Hi, Helge.
Are you sure you are linking against the correct version of the
qtjambi.lib library and that it's located at the correct location (if
you're using the original .pro file from the generator example, this
would be "../lib")

that could have anything to do with it? I noticed the error:
LINK : warning LNK4098: defaultlib 'MSVCRTD' conflicts with use of other
libs; use /NODEFAULTLIB:library
this occurs probably since moc complined about this dll not existing,
thus leading to that I had
to copy this into $(QTDIR)/bin manually.
How can I set options like /NODEFAULTLIB:MSVCRTD.dll in the pro file?

I haven't seen what your pro-file looks like, but wouldn't you have to
set it up to use your new installation of Qt Jambi? I don't see any
reference to your qtjambi-win-1.0.0-tp3 directory in any of the output
you pasted.
In the original pro-file, the destination directory is set to "../lib"
and this same directory is set as the location of the library files. If
you have changed the pro-file and want to load the libraries from
somewhere else, you will have to change the line that says LIBS += in
the pro-file:
Instead of
LIBS += -L$$DESTDIR -l$$QTJAMBI_LIB_NAME
put something like
LIBS += -L/path/to/qtjambi-tp3 -l$$QTJAMBI_LIB_NAME
In your original output, the linker's output was directed to
c:\java\lib\maptool, which could indicate that this is the problem.

Sorry, same problem still if I change the destination directory
variables back to original settings. Do you have any clue on how to set
generic options to the linker? I think this might solve the problem.

In the .pro-file, you can set the linker options by adding e.g.
QMAKE_LFLAGS += /NODEFAULTLIB:library
Hope that helps.
I did try linking the generator example from TP3 against the qtjambi.lib
from TP2 and got the exact same error messages that you got, however.

Sorry, you were right. I had some setting in the environment variable
LIB that I configured loooong time ago.
Works now.
