| 21 | .SH NAME | |
| 22 | deb\-shlibs \- Debian shared library information file | |
| 23 | . | |
| 24 | .SH DESCRIPTION | |
| 25 | .PP | |
| 26 | .B shlibs | |
| 27 | files map shared library names and versions | |
| 28 | .RI ( sonames ) | |
| 29 | to dependencies suitable for a package control file. There is one | |
| 30 | entry per line. Blank lines are \fBnot\fP allowed. Lines beginning | |
| 31 | with an \fB#\fP character are considered commentary, and are ignored. | |
| 32 | All other lines must have the format | |
| 33 | .IP | |
| 34 | .RI [ type\fB:\fP ] | |
| 35 | .I library | |
| 36 | .I version | |
| 37 | .I dependencies | |
| 38 | .PP | |
| 39 | The \fIlibrary\fP and \fIversion\fP fields are whitespace-delimited, | |
| 40 | but the \fIdependencies\fP field extends to the end of the line. The | |
| 41 | \fItype\fP field is optional and normally not needed. | |
| 42 | .PP | |
| 43 | The \fIdependencies\fP field has the same syntax as the \fBDepends\fP | |
| 44 | field in a binary control file, see \fBdeb\-control\fP(5). | |
| 45 | . | |
| 46 | .SH EXAMPLES | |
| 47 | .PP | |
| 48 | The | |
| 49 | .B shlibs | |
| 50 | file for a typical library package, named | |
| 51 | .IR libcrunch1 , | |
| 52 | that provides one library whose soname is | |
| 53 | .IR libcrunch.so.1 , | |
| 54 | might read | |
| 55 | .IP | |
| 56 | libcrunch 1 libcrunch1 (>= 1.2-1) | |
| 57 | .PP | |
| 58 | The \fIdependencies\fP | |
| 59 | must mention the most recent version of the package that added new | |
| 60 | symbols to the library: in the above example, new symbols were added to | |
| 61 | version 1.2 of | |
| 62 | .IR libcrunch . | |
| 63 | This is not the only reason the dependencies might need to be | |
| 64 | tightened. | |
