Hi, When trying yum update, I have this message : Error: Missing Dependency: glibc = 2.3.4-2.19 is needed by package glibc-devel but when I type : # rpm -qi glibc I get : Name : glibc Relocations: (not relocatable) Version : 2.3.4 Vendor: CentOS Release : 2.19 ... What should I do ? Thanks for your help Guillaume
