This project is for analyzing the relationship between friends defined in DaTouTie which is a picture sync mobile app that can push&pull pictures to&from your friends automaticly.

you should build the running enviroment for this app:

1. build BerkeleyDB 4.7.x libevent 1.4.x for memcacheq and then build memcacheq
2. running memcacheq : memcacheq -d -r -p20201 -H /data1/memcacheq -N -R -v -L 1024 -B 1024 > /data1/mq_error.log 2>&1  
3. config the ~/conf/link_mining.xml to match your running enviroment
4. build redis and deps/hiredis/,both make installed
5. config redis and running redis: redis-server (CONF_PATH)/redis.conf
6. config the ~/conf/redis.conf(not the same as conf_file above,this is the redis_conf_file for link_mining).
7. now you can build this project and run it like ./link_mining -f ../conf/link_mining.xml

NOTE:
1. redis_err_log file path hardcoded in libredisclient.a
2. change redisConnectWithTimeout to redisConnect in libredisclient.a since the former one is no longer supported.
3. the XML parser maintains its own memory pool,so you dont need to care about the inner memory management,like free the xode_to_str string.
