samba - May 1998 - Error while linking samba-1.9.18p6 using SunOS 5.5.1

Here is the output:

Linking smbd
Undefined                       first referenced
 symbol                             in file

ld: fatal: Symbol referencing errors. No output written to smbd


There was no problem with samba-1.9.18p6.

Any idea ?
