Modify the code to use the linux curl libraries to deliver data to the Weather Underground Site

Introduction

The current code, which talks to the weather underground site using sockets just upped and stopped working one day. I couldn't see any reason for this,so assume that it's something that's changed on the WU site itself. So I rewrote the relevant functions to use thefreely available curl libraries.

Description of Patch

This is a replacement for the http_request_url function inlinux2300.c, at approx line 245.

Installation of Patch

1. Install the libcurl development support ( redhat: yum install libcurl-devel, debian/ubuntu: apt-get install libcurl4-openssl-dev )

2. Edit the file linux2300.c, and perform the following:

c. line 18:add

#include <curl/curl.h>

after the other system includes.

at c. line 246, replace the function http_request_url with

int http_request_url(char *urlline)
{
CURL *curl;
CURLcode res;

if ( (curl = curl_easy_init()) )
{
curl_easy_setopt ( curl, CURLOPT_URL, urlline );
res = curl_easy_perform ( curl );
curl_easy_cleanup ( curl );
}
return 0;
}

3. Edit the file Makefile, and change the following line

CC_LDFLAGS = -lm

to

CC_LDFLAGS = -lm -lcurl

4. make wu2300 && make install
