Проблема при компиляции 3proxy

[ATT]

Добрый день!
Добрый день! При компиляции на ubuntu (make -f Makefile.Linux) выдает такую ошибку:

In file included from 3proxy.c:10:0:
proxy.h:19:19: fatal error: stdio.h: No such file or directory

По рекомендации производителя нужно установить stdlib, однако при sudo apt-get install stdlib
пишет

Unable to locate package stdlib

Подскажите плз, как установить эту stdlib.
