OpenWRT C CGI helloworld!

We don't want to install php on our OpenWRT since it's too big,We can write a small cgi in c(like php)

You must finish the No.2 and No.3 issue first

cd /home/workplace/OpenWrt-SDK-ramips-for-linux-x86_64-gcc-4.8-linaro_uClibc-0.9.33.2
cd package/helloworld/src/
vi helloworld.c    #content as follow
#include <stdio.h>
#include <stdio.h> //getenv

int main(void){
        printf("Content-Type: text/html\n\n");
        printf("GET:%s\n",getenv("QUERY_STRING"));
        return 0;
}
cd ../../../
make 
cd bin/ramips/packages/
scp helloworld_1_ramips_24kec.ipk root@192.168.8.1:/usr/bin
