5 dh_shlibdeps - calculate shared library dependancies

19 dh_shlibdeps is a debhelper program that is responsible for calculating
20 shared library dependancies for packages.
22 This program is merely a wrapper around L<dpkg-shlibdeps(1)> that calls it
23 once for each package listed in the control file, passing it
24 a list of ELF executables and shared libraries it has found.
30 =item B<-u>I<params>, B<--dpkg-shlibdeps-params=>I<params>
34 Pass "params" to L<dpkg-shlibdeps(1)>.
36 =item B<-X>I<item>, B<--exclude=>I<item>
38 Exclude files that contain "item" anywhere in their filename from being
39 passed to dpkg-shlibdeps. This will make their dependancies be ignored.
40 This may be useful in some situations, but use it with caution. This option
41 may be used more than once to exclude more than one thing.
43 =item B<-l>I<directory>
45 Before dpkg-shlibdeps is run, LD_LIBRARY_PATH will be set to the specified
46 directory. This is useful for multi-binary packages where a library
47 is built in one package and another package contains binaries linked
48 against said library. Relative paths will be made absolute for the
49 benefit of dpkg-shlibdeps.
57 foreach my $package (@{$dh{DOPACKAGES}}) {
58 my $tmp=tmpdir($package);
59 my $ext=pkgext($package);
64 # Generate a list of ELF binaries in the package, ignoring any
65 # we were told to exclude.
67 if (defined($dh{EXCLUDE_FIND}) && $dh{EXCLUDE_FIND} ne '') {
68 $find_options="! \\( $dh{EXCLUDE_FIND} \\)";
70 foreach my $file (split(/\n/,`find $tmp -type f \\( -perm +111 -or -name "*.so*" \\) $find_options`)) {
71 # TODO: this is slow, optimize. Ie, file can run once on multiple files..
73 if ($ff=~m/ELF/ && $ff!~/statically linked/) {
80 # Force the path absolute.
81 unless ($dh{L_PARAMS}=~m:^/:) {
82 $dh{L_PARAMS}=getcwd()."/$dh{L_PARAMS}";

95 This program is a part of debhelper.
