NAME
deb-symbols - Debian's extended shared library information file
SYNOPSIS
symbols
DESCRIPTION
The format for an extended shared library dependency information entry in these files is:
<library soname> <main dependency template>
[ | <alternative dependency template> ]
[ ... ]
[ * <field-name>: <field value> ]
[ ... ]
<symbol> <minimal version>[ <id of dependency template> ]
The library soname is exactly the value of the SONAME field as exported by objdump(1). A dependency template is a dependency where #MINVER#
is dynamically replaced either by a version check like "(>= minimal version)" or by nothing (if an unversioned dependency is deemed suffi-
cient).
Each exported symbol (listed as name@version, with version being "Base" if the library is not versioned) is associated to a minimal version
of its dependency template (the main dependency template is used if id of dependency template is not present). The first alternative depen-
dency template is numbered 1, the second one 2, etc.
Each entry for a library can also have some fields of meta-information. Those fields are stored on lines starting with an asterisk. Cur-
rently, the only valid field is Build-Depends-Package, it indicates the name of the "-dev" package associated to the library and is used by
dpkg-shlibdeps to make sure that the dependency generated is at least as strict as the corresponding build dependency.
