Hi Martin,

 

You are right. I messed up between shared and static libraries. There is a
jpeg lib, which I was initially building as static lib and linking to the
main project and I don't know why

it was not getting linked. I built it as SHARED lib  and the whole project
compiled successfully.

 

Thanks A lot.

 

Hi Eric,

 

Thanks for the  <http://www.cmake.org/Wiki/BuildingWinDLL> BuildingWinDLL
link. It was very helpful.

 

 I compiled the lib as SHARED (the library which was not found by the
linker) and project compiled sucessfully.

Though I still don't understand why was it not getting linked when I
compiled it as STATIC library? 

 

Thanks a lot for replying my questions.

 

Regards

Avanindra

If you're seeing a 'Librarian' tab instead of a 'Linker' tab, then you're
building a static library, not a dll.

I'm not sure which you are expecting.

Could you post the results of the build?  Seeing the actual errors would
help.

Do you handle the visibility of symbols in libraries properly?
On Linux the [usual] default is to have all symbol exported whereas
it's the converse on Windows (no symbol exported unless specified).

You have to use
__declspec(dllexport)
__declspec(dllimport)
statement in the Windows case.
