deb-symbols - Debian’s extended shared library information file
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
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 dependency
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. Currently,
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.
