25 | # development packages for some libraries. The runtime packages contain shared | |

27 | # the development packages supplement this with versionless shared libraries | |
28 | # (e.g., libgdbm.so). | |
29 | # | |
30 | # If you want to link against such a library, you must install the development | |
31 | # version of the package. | |
32 | # | |
33 | # These packages use a -dev naming convention in both Debian and Red Hat: | |
34 | # libgdbmg1 (non-development version of GNU libc 2-linked GDBM library) | |
35 | # libgdbmg1-dev (development version of GNU libc 2-linked GDBM library) | |

37 | # Debian or Red Hat you have the -dev packages installed. | |
