I'm getting a bizarre compiler error when trying to compile a c++ UDP client program.
g++ -o client Udp.cpp ClientMain.c -I. -lpthread
In file included from ClientMain.c:1:0:
Udp.h: In destructor ‘CUdpMsg::~CUdpMsg()’:
Udp.h:103:43: error: ‘free’ was not declared in this scope

I have the following declared at the beginning of my cpp file.
#include <netinet/in.h>
#include <netdb.h>
#include <string.h>
#include <stdlib.h>
#include <unistd.h>
#include <stdio.h>
#include <arpa/inet.h>
#include <fcntl.h>
#include <ifaddrs.h>
#include <net/if.h>
#include <cstdlib>
#include <string>
#include <stdlib.h>
#include <cstring>
#include <errno.h>
functions like 'memcpy' should be declared in string.h... I have it (and string and cstring) all declared, and I'm still getting these compiler errors. Does anyone have a clue why this is happening? Thanks.

if you're including the C headers (i.e. the .h ones) – MSalters<stdlib.h>
