Make sure your FTP library is linked properly – billz Feb 14 '13 at 07:01
I've added the lib file in project options.. But still get these errors – user2071019 Feb 14 '13 at 07:01
I feel you are on VS IDE, have you added library path ? – billz Feb 14 '13 at 07:04
Yes, in Additional Library Directories in Linker-General – user2071019 Feb 14 '13 at 07:06
@user2071019 only additional directories, or did you actually add the `.lib` to input? – Luchian Grigore Feb 14 '13 at 07:07
Sure in Linker-Input-Additional Depencies – user2071019 Feb 14 '13 at 07:08
The reason for that is that you are not linking the proper libraries. – Mark Garcia Feb 14 '13 at 07:08
Well, I've used it in another project and everything was ok. Maybe something is wrong because this is CLR project and I'm Marshalling C++ unmanaged class? Actually wrapping to managed C++ – user2071019 Feb 14 '13 at 07:10
@user2071019 Did you define `FTP::FTP`? can you show your code? – billz Feb 14 '13 at 07:32
What do you mean? Do I have FTP() constructor in class FTP? If so - yes. – user2071019 Feb 14 '13 at 07:35
