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：

Summary : Object files for development using standard C libraries.
Description :
The glibc-devel package contains the object files necessary
for developing programs which use the standard C libraries (which are
used by nearly all programs). If you are developing programs which
will use the standard C libraries, your system needs to have these
standard object files available in order to create the executables.
Install glibc-devel if you are going to develop programs which will
use the standard C libraries.

Summary : The GNU libc libraries
Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.
