Compiler Error Q3PtrList (VS2005 on XP and Qt4.3.3)

[stefan1981]

Hi,

I am using qt4.3.3.

when I compile with nmake and VS 8 i get a linker error "unresolved external symbol" for Q3PtrList<>. With VS 6 it works fine, also with VS 8 and Windows Vista.

Its the combination VS8, Windows XP and Qt4.3.3. I know I could replace the QPtrList with Qlist<> but i wonder why it works on VS6..

Any ideas?

Regards,

stef

Do you link your application with Qt3Support module?

Hi,

yes I link with Q3Support-Module. The problem is, that the error only occurs in some sources. In others I can use Q3PtrList without errors.

The error is as follows:

status.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) const Q3PtrList<char>::`vftable'" (__imp_??_7?$Q3PtrList@D@@6B@)

Could that be a linker problem of visual studio 2005? i am using SP1.

regards

Throw away Qt3 support - especially when it's that easy like with Q3PtrList.
Looks like you don't link against a module which is exporting Q3PtrList<char> but use a header from that module. Look in which header the Q3PtrList<char> is exported.

Okay, I have replaced the occurences of Q3PtrList in these files with the QList. But I still get the error even though I dont't use the Q3PtrList any more.

I don't have an idea why??

okay i solved it. there is a bug when you include both Q3StrList and Q3PtrList and use a Q3PtrList<char> in the code.

thats when the linker error occurs.
