Work requirements, makeshift office environment on Linux systems, CentOS 6.5 using the system installation is going smoothly, the last card on the network, found that the network is unavailable. This case records problems found in the process of locating and processing sectors, the brothers encountered the same problem for reference.
And positioning problems found

Solve a try:
By setup configuration card (detailed steps are omitted, there is a lot of Baidu search guide)
configuration is complete, the configuration file
cat ifcfg-eth0

Start card
service network restart
eth0: Device eth0 does not seem to be present, delaying initializa [FAILED]
Unable to get the physical location from the configuration, as well as information lspci see if the card point of view, is likely to be the driving issue.
Try to solve the two:
Through extensive searches to obtain driver
encountered a problem: the lack of development of core compiler error. Installation developing core
continues compilation

For non-C ++ staff, I see this error relatively ignorant force, is it too new drive official website
to find online in response to the question, but there are similar corresponding old installation packages are difficult to obtain. Here toss a few hours to find resources, many fruitless attempts.
final plan
Almost desperate, return to the starting point of the problem, try to solve the problem under the compiler.
View compile information, as if to say re-define the methods already exist, it is estimated that the problem of different operating systems corresponding version appears
to find the corresponding source code, try commenting out the method, the middle some small problems, unrelated to the overall situation. Eventually, after several commented out method, the compiler actually magical success.
View card information, a lot more [omitted a lot of card information, display the last]
