<para>
Upgrading this package to a new major version will require rebuilding
of many other packages. If some packages that use the librares built
by icu4c-&icu-major; are rebuilt, they will use the new libraries
while current packages will use the previous libraries. If the
linux application loader (/usr/lib/ld-linux-x86-64.so.2) determines
that both the old and new libraries are needed, it will probably
cause an address conflict when resolving needed symbols and will
result in the application failing.

To determine what external libraries are needed (directly or indirectly)
by an application or a library, run:

or to see only the directly needed libraries:

<screen><userinput>readelf -d &lt;application or library&gt; | grep NEEDED</userinput></screen>
