-Ppackage-build-dir
Scan package-build-dir instead of debian/tmp.
-ppackage
Define the package name. Required if more than one binary
package is listed in debian/control (or if there's no
debian/control file).
-vversion
Define the package version. Defaults to the version
extracted from debian/changelog. Required if called
outside of a source package tree.
-elibrary-file
Only analyze libraries explicitly listed instead of
finding all public libraries. You can use shell patterns
used for pathname expansions (see the File::Glob(3perl)
manual page for details) in library-file to match multiple
libraries with a single argument (otherwise you need
multiple -e).
-ldirectory
Prepend directory to the list of directories to search for
private shared libraries (since dpkg 1.19.1). This option
can be used multiple times.
Note: Use this option instead of setting LD_LIBRARY_PATH,
as that environment variable is used to control the run-
time linker and abusing it to set the shared library paths
at build-time can be problematic when cross-compiling for
example.
-Ifilename
Use filename as reference file to generate the symbols
file that is integrated in the package itself.
-O[filename]
Print the generated symbols file to standard output or to
filename if specified, rather than to
debian/tmp/DEBIAN/symbols (or package-build-
dir/DEBIAN/symbols if -P was used). If filename is pre-
existing, its contents are used as basis for the generated
symbols file. You can use this feature to update a
symbols file so that it matches a newer upstream version
of your library.
-t Write the symbol file in template mode rather than the
format compatible with deb-symbols(5). The main difference
is that in the template mode symbol names and tags are
written in their original form contrary to the post-
processed symbol names with tags stripped in the
compatibility mode. Moreover, some symbols might be
omitted when writing a standard deb-symbols(5) file
(according to the tag processing rules) while all symbols
are always written to the symbol file template.
-c[0-4]
Define the checks to do when comparing the generated
symbols file with the template file used as starting
point. By default the level is 1. Increasing levels do
more checks and include all checks of lower levels. Level
0 never fails. Level 1 fails if some symbols have
disappeared. Level 2 fails if some new symbols have been
introduced. Level 3 fails if some libraries have
disappeared. Level 4 fails if some libraries have been
introduced.
This value can be overridden by the environment variable
DPKG_GENSYMBOLS_CHECK_LEVEL.
-q Keep quiet and never generate a diff between generated
symbols file and the template file used as starting point
or show any warnings about new/lost libraries or new/lost
symbols. This option only disables informational output
but not the checks themselves (see -c option).
-aarch Assume arch as host architecture when processing symbol
files. Use this option to generate a symbol file or diff
for any architecture provided its binaries are already
available.
-d Enable debug mode. Numerous messages are displayed to
explain what dpkg-gensymbols does.
-V Enable verbose mode. The generated symbols file contains
deprecated symbols as comments. Furthermore in template
mode, pattern symbols are followed by comments listing
real symbols that have matched the pattern.
-?, --help
Show the usage message and exit.
--version
Show the version and exit.
