NAME
deb-symbols - Debian's extended shared library information file
SYNOPSIS
DEBIAN/symbols
DESCRIPTION
The symbol files are shipped in Debian binary packages, and its format is a subset of the
template symbol files used by dpkg-gensymbols(1) in Debian source packages.
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 sufficient).
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 always used and will end up being combined with the dependency
template referenced by id-of-dependency-template if present). The first alternative
dependency template is numbered 1, the second one 2, etc. Each column is separated by
exactly a single whitespace.
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 fields are:
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 (since dpkg 1.14.13).
Build-Depends-Packages
The same as Build-Depends-Package but accepts a comma-separated list of package names
(since dpkg 1.20.0). This field will override any Build-Depends-Package field
present, and is mostly useful with "-dev" packages and metapackages depending on
these, say for a transition period.
Allow-Internal-Symbol-Groups
It indicates what internal symbol groups should be ignored, as a whitespace separated
list, so that the symbols contained in those groups get included in the output file
(since dpkg 1.20.1). This should only be necessary for toolchain packages providing
those internal symbols. The available groups are system dependent, for ELF and GNU-
based systems these are aeabi and gomp.
Ignore-Blacklist-Groups
A deprecated alias for Allow-Internal-Symbol-Groups (since dpkg 1.20.1, supported
since dpkg 1.17.6).
