Dear ALL: I have Problem With bcache-tools compile , I got a problem with a new upgrade kernel from 2.6.x to 4.4.13 on Centos 6.9 but my Base is on Centos 6.9 , it means a lot of libs are old for BCACHE . Bcache was introduce in Kernel 3.X When I compiled bcache-tools it happened alhost ~]# gcc -v Using built-in specs.
