mwldsym2.exe: Undefined symbol in Carbide.C++ 1.3

[ValentinK]

Hello,

Strange problem with Carbide.C++ 1.3 and linking.
Few quetions to Carbide developers team.
Most of errors with linking was solved. Need to help with 3 last.

My project compiles and links good on GCCE target and fails link on WINSCW.

Listing is quite big

Reason for CMySelectionListDialog not linked well is quite odd.
Class CMySelectionListDialog declared in .cpp file, private class that used only inside this cpp. Moving declaration into .h solved part of errors.
And now I got 5 errors:

Undefined symbol: 'void * CAknSettingItemList::ExtensionInterface(class TUid) (?ExtensionInterface@CAknSettingItemList@@UAEPAXVTUid@@@Z)'

Undefined symbol: 'void CAknView::Reserved_MtsmObject(void) (?Reserved_MtsmObject@CAknView@@UAEXXZ)'

Undefined symbol: 'void CAknView::Reserved_MtsmPosition(void) (?Reserved_MtsmPosition@CAknView@@UAEXXZ)'

Undefined symbol: 'void CBaseView:: DoActivateL(class TVwsViewId const &, class TUid, class TDesC8 const &) (?DoActivateL@CBaseView@@EAEXABVTVwsViewId@@VTUid@@ABVTDesC8@@@Z)'

Undefined symbol: 'void CBaseView:: DoDeactivate(void) (?DoDeactivate@CBaseView@@EAEXXZ)'

Investigating more,
class CBaseView : public CAknView.

was declared as private:
void CBaseView:: DoActivateL(class TVwsViewId const &, class TUid, class TDesC8 const &)
void CBaseView:: DoDeactivate(void)
and in CAknView declared as protected.

Now I got 3 errors.

Undefined symbol: 'void * CAknSettingItemList::ExtensionInterface(class TUid) (?ExtensionInterface@CAknSettingItemList@@UAEPAXVTUid@@@Z)'
Undefined symbol: 'void CAknView::Reserved_MtsmObject(void) (?Reserved_MtsmObject@CAknView@@UAEXXZ)'
Undefined symbol: 'void CAknView::Reserved_MtsmPosition(void) (?Reserved_MtsmPosition@CAknView@@UAEXXZ)'

And I have no idea how to fix it.

You should consider checking the necessary libraries in the SDK Help. If it does not help (however it should), you can do a binary search for the mangled symbol names. As I see the messages are coming from a WINSWC build, so check in epoc32\release\winscw\udeb\*.lib

Please read my post again. Project Do work for GCCE. and It linked and worked fine in VS.2005 Carbide.vs 3.01. But it fails in link stage on Carbide.C++ 1.3 with very strage message:
I do use CAknView, but surely I dont it private: functions like Reserved_MtsmObject.

[wizard_hu_]

Such symbols do not exist in my SDK (3rd MR), but there are some resembling ones:
?ExtensionInterface@CAknSettingItemList@@UAEPAXVTUid@@@Z seems to be
?ExtensionInterface@CAknSettingItemList@@EAEPAXVTUid@@@Z
?Reserved_MtsmObject@CAknView@@UAEXXZ is
?Reserved_MtsmObject@CAknView@@EAEXXZ
and
?Reserved_MtsmPosition@CAknView@@UAEXXZ is
?Reserved_MtsmPosition@CAknView@@EAEXXZ
And they reside in avkon.lib
Unfortunately I am not really sure about the details, but in http://en.wikipedia.org/wiki/Microso..._Name_Mangling U and E say public and private virtual method respectively. Can it happen that CBaseView is a base, and you inherit it privately sometimes?

[ValentinK]

I define this missed virtual private functions with empty implementations, and it now links.
CBaseView was derived from CAknView.
CAknExSettingListListbox from CAknSettingItemList. Both public.
