>Severity: non-critical
>Priority: low

>Class: change-request
>Release: 1.4
>Environment: Sun, Solaris 8, sparc
System: SunOS afstest 5.8 Generic_117350-19 sun4u sparc SUNW,UltraAX-i2
Architecture: sun4
>Description:
We use both the static and shared versions of the MIT krb5 libraries.
The static version of k5crypto (libk5crypto.a) produces the following
complaint when used on a Solaris machine:
ild: the archive /usr/local/lib/libk5crypto.a has entries with the same name -- consistency checks during incremental links are not possible for these entries
This results because there are two arcfour.o files
(lib/crypto/enc_provider/arcfour.o and lib/crypto/arcfour/arcfour.o) and
two string_to_key.o files (lib/crypto/string_to_key.o and
lib/crypto/arcfour/string_to_key.o) used to build the k5crypto library.
The actual symbols provided by each duplicate file name are different.
The library still works ... but the complaint message is distracting.
The "problem" does not affect the shared library.
>How-To-Repeat:
Link any program requiring use of the k5crypto library, such as "kinit",
with the static libraries instead of the shared libraries.
>Fix:
The easiest way to correct this is to rename the files in
src/lib/crypto/arcfour. This would also require a few minor changes in some
of the files. The following small script would provided the appropriate
changes. Admittedly, the header files don't need to be renamed but it
provides for consistency.
