[Qt-interest] Windows DLL Linking Static Qt

[Finley Lee]

I'm attempting to build a Windows DLL which links to a static build of
the Qt library.  When I build my DLL, the linker emits the following
errors:

 

qtdll.obj : warning LNK4217: locally defined symbol
??0QObject@@QAE at PAV0@@Z (public: __thiscall QObject::QObject(class
QObject *)) imported in function "public: __thiscall
TestClass::TestClass(void)" (??0TestClass@@QAE at XZ)

qtdll.obj : warning LNK4217: locally defined symbol ??1QObject@@UAE at XZ
(public: virtual __thiscall QObject::~QObject(void)) imported in
function "public: virtual __thiscall TestClass::~TestClass(void)"
(??1TestClass@@UAE at XZ)

qtdll.obj : error LNK2001: unresolved external symbol "public: virtual

debug\QtDLL2.dll : fatal error LNK1120: 3 unresolved externals

NMAKE : fatal error U1077: '"c:\Program Files (x86)\Microsoft Visual
Studio 9.0\VC\BIN\link.EXE"' : return code '0x460'

Stop.

NMAKE : fatal error U1077: '"c:\Program Files (x86)\Microsoft Visual
Studio 9.0\VC\BIN\nmake.exe"' : return code '0x2'

Stop.

 

My qmake file looks like this:

 

TEMPLATE = lib

LANGUAGE = C++

CONFIG += qt dll debug_and_release

VERSION = 2.9.0

 

SOURCES += qtdll.cpp

 

I have tried to add 'static' and remove 'shared' from the CONFIG
variable, but that doesn't seem to make any difference.   I am new to
Qt, so I'm sure I'm missing something obvious.  Any idea what it might
be?

 

Thanks,
