带devel（develop）的包，俗称开发包。功能上与普通包相同，但体积更大
使用rpm -qi看看这两类包的区别：

URL : http://sources.redhat.com/glibc/Summary : Object files for development using standard C libraries.Description :The glibc-devel package contains the object files necessaryfor developing programs which use the standard C libraries (which areused by nearly all programs). If you are developing programs whichwill use the standard C libraries, your system needs to have thesestandard object files available in order to create the executables.Install glibc-devel if you are going to develop programs which willuse the standard C libraries.

URL : http://sources.redhat.com/glibc/Summary : The GNU libc librariesDescription :The glibc package contains standard libraries which are used bymultiple programs on the system. In order to save disk space andmemory, as well as to make upgrading easier, common system code iskept in one place and shared between programs. This particular packagecontains the most important sets of shared libraries: the standard Clibrary and the standard math library. Without these two libraries, aLinux system will not function.
