(CDT) Object files for development using standard C libraries.
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.
