VS 2003 Qt 3-->4 migration issue: what to do with "qt-mtnc321.lib" references?
Message 1 in thread
Hi everyone,
I'm porting a Qt 3 project to Qt 4, and am having trouble with linking. The
Visual Studio 2003 project I inherited makes reference to a library file
named "qt-mtnc321.lib", which I don't have, as I've only installed Qt4 on my
desktop. I do have qtmain.lib and Qt3Supportd4.lib in my linker paths.
I've also run the qt3to4 porting tool on all source files.
If I remove qt-mtnc321.lib from the linker section of the project I get a
slew of linker errors. Stuff like:
error LNK2001: unresolved external symbol "__declspec(dllimport) public:
__thiscall QBoxLayout::QBoxLayout(enum QBoxLayout::Direction,class QWidget
*)"
pops up. A ton of those messages. Apparently I'm missing a library file
somewhere, but am not sure what it might be. If you have any ideas or leads
on this I'd appreciate it. Thanks!

To me it looks like you are missing the qtgui lib :)
But then again I haven't used Qt 3, so I cannot tell you what
qt-mtnc312.lib does without looking it up.
Regards,
Thomas
