Добрый день, столкнулся с проблемой установки библиотеки cURL на Билдер С++ , сделал все как тут показанно
http://www.xakep.ru/magazine/xa/121/092/1.asp
Линкер ругаеться :
Build

Как мне решить эту проблему.Заранее спасибо.
PS часть кода :
/*
ac-service.info C++ w/CURL usage example
1. replace variable "ackey" with your own
2. replace variable "captchafile" with your own captcha filename
3. compile with g++ option -lcurl
