Building Kerberos on AIX

Mon May 6 07:42:51 EDT 2013

Hello Greg,

In the file changepw.c there is a function  *krb5int_setpw_result_codestring
*at line 344 ,which the linker is not able to resolve. In my setup the
libraries linked to this file are

(ld): lib ../../lib/libk5crypto.so
(ld): lib ../../lib/libcom_err.so
(ld): lib ../../lib/libkrb5support.so
(ld): lib /usr/lib/libpthreads.a
(ld): lib /usr/lib/libc.a
(ld): lib /usr/lib/librtl.a

Please let me know if I need to link any other libraries to this file.

-Regards
 Mohit
