- This file is intended only as a <em>temporary</em> fix if
- your binaries or libraries depend on a library whose package
- does not yet provide a correct <file>shlibs</file> file.
- </p>

- <p>
- We will assume that you are trying to package a binary
- <tt>foo</tt>. When you try running
- <prgn>dpkg-shlibdeps</prgn> you get the following error
- message (<tt>-O</tt> displays the dependency information on
- <tt>stdout</tt> instead of writing it to
- <tt>debian/substvars</tt>, and the lines have been wrapped
- for ease of reading):
- <example compact="compact">
-$ dpkg-shlibdeps -O debian/tmp/usr/bin/foo
-dpkg-shlibdeps: warning: unable to find dependency
- information for shared library libbar (soname 1,
- path /usr/lib/libbar.so.1, dependency field Depends)
-shlibs:Depends=libc6 (>= 2.2.2-2)
- </example>
- You can then run <prgn>ldd</prgn> on the binary to find the
- full location of the library concerned:
- <example compact="compact">
-$ ldd foo
-libbar.so.1 => /usr/lib/libbar.so.1 (0x4001e000)
-libc.so.6 => /lib/libc.so.6 (0x40032000)
-/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
- </example>
- So the <prgn>foo</prgn> binary depends on the
- <prgn>libbar</prgn> shared library, but no package seems to
- provide a <file>*.shlibs</file> file handling
- <file>libbar.so.1</file> in <file>/var/lib/dpkg/info/</file>. Let's
- determine the package responsible:
- <example compact="compact">
-$ dpkg -S /usr/lib/libbar.so.1
-bar1: /usr/lib/libbar.so.1
-$ dpkg -s bar1 | grep Version
-Version: 1.0-1
- </example>
- This tells us that the <tt>bar1</tt> package, version 1.0-1,
- is the one we are using. Now we can file a bug against the
- <tt>bar1</tt> package and create our own
- <file>debian/shlibs.local</file> to locally fix the problem.
- Including the following line into your
- <file>debian/shlibs.local</file> file:
- <example compact="compact">
-libbar 1 bar1 (>= 1.0-1)
- </example>
- should allow the package build to work.
- </p>
-
- <p>
- As soon as the maintainer of <tt>bar1</tt> provides a
- correct <file>shlibs</file> file, you should remove this line
- from your <file>debian/shlibs.local</file> file. (You should
- probably also then have a versioned <tt>Build-Depends</tt>
- on <tt>bar1</tt> to help ensure that others do not have the
- same problem building your package.)
