Ze strony http://curl.haxx.se/download.html pobrałem
Win32 2000/XP 7.25.0 libcurl SSL enabled Günter Knauf 3.12 MB
Po rozpakowaniu wrzuciłem wszystko co było w
\include\curl
do
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include
następnie skopiowałem jeden z przykładów, konkretnie
http://curl.haxx.se/libcurl/c/ftpupload.html
do pustego projektu w VS10 , i aż zaroiło się od podkreśleń. Po zamianie
#include <curl/curl.h>
na #include <curl.h>
zrobiło się o wiele lepiej, ale program dalej nie chce się uruchomić z powodu dwóch błędów.

_FMT_SIZE_T w ogóle nie jest widoczne.
Skąd te błędy skoro biblioteka curl się załadowała, a program jest żywcem zerznięty z oficjalnej dokumentacji? Dla ścisłości - treść którą próbowałem poddać kompilacji:
