Linux g++ compile C + + connection Oracle (OCCI) problems and Solutions

Original: http://lshirley2009.javaeye.com/blog/811301 article Category: C + + programmingAs a result of the project, began to learn C + +, just contact for more than half a month, today's reference online example, wrote a simple C + + connection to Oracle's demo, but the use of g++ compile time is not smooth, not the newspaper this fault is that, the last reference online solutions and personal understanding, finally The problems and solutions in compiling are summarized.
