(I noticed a question like this, but he was 2 years old.)
I am developing a Windows Form application in Visual C ++ 2008 that uses the FTP function libCurl. Although I added the lib and include directories in the include and library search paths, added libcurl_imp.lib to Additional Dependencies and added CURL_STATICLIB to the Preproccessor definitions, I get 14 linker errors when creating it. I checked the cURL FAQ and some Google errors, but I haven't found a solution yet. The linker errors are as follows:

(I obscured the name of the project.)
What does this mean, how can I prevent this? Thank:)
UPDATE
I switched to Code :: Blocks and now become the native Win32 graphical application. I do not get all these linker errors, but I get something:
ld.exe cannot find -lcurl.lib
include lib . , lib - libcurl.lib, curl.lib. , ?
EDIT: , , libcurl.lib .
-lcurl " ",
ld.exe cannot find -lcurl
.lib.
