Re: Official CGMINER thread - CPU/GPU miner in C for linux/windows/osx
I think you grossly overestimate how many people are using centos 
Anyway I've committed a fix to the git tree which prevents using just the sockopt function if the version of curl is too old. This should fix it building on older curls.
I started out trying to use CentOS before switching to F15 after I decided that manually compiling every component and half of the compilers to get pretty much any of the miners working wasn't worth the hassle and was going to lead to a broken installation anyway. Fortunately, I'm not trying to do anything else with the machine I am running Linux on at the moment, but anyone who is mining on the side might have good reasons to run CentOS.Anyway I've committed a fix to the git tree which prevents using just the sockopt function if the version of curl is too old.
