Installation guide

You might need to link your application with one of these libraries if it
depends on the behavior of a BSD or System V library routine.
7.6.1 Changes in Libraries
The following list summarizes differences between ULTRIX and DIGITAL
UNIX system libraries:
• Merger of libraries into the libc library
Unlike ULTRIX systems, the internationalization library, libi.a, the
POSIX library, libcP.a, and the System V library, libcV.a, are part
of the standard C library, libc, except where conflicts between
System V and other standards exist.
Remove references to these libraries from your cc or make command
line.
• Separation of libraries from the libc library
Unlike ULTRIX systems, the libmld library is not part of the standard
C library, libc.
Add a reference to this library in your cc or make command line if you
want to include these functions.
• Movement of functions between libraries
On ULTRIX Version 4.3A and earlier systems, the
DXmHelpSystemOpen, DXmHelpSystemDisplay, and
DXmHelpSystemClose functions were contained in the libDXm.On
DIGITAL UNIX systems, these functions are contained in libbkr.
(This difference does not apply to ULTRIX Version 4.4 systems.)
• Libraries supporting unavailable features
A number of libraries are not included in the DIGITAL UNIX system
due to differences in features between ULTRIX and DIGITAL UNIX
systems. These include:
– Extended SNMP Agent: libsnmp.a
– Kerberos library routines: libkrb.a, libknet.a, libdes.a, and
libacl.a
– Authorization library: libauth.a
– ULTRIX/SQL library: libsql.a
– Graphics and plotting libraries (located in /usr/lib on ULTRIX
systems): plot, plotaed, plotbg, plotdumb, plotgigi, plotgrn,
plot2648, plot7221, plotimagen, 300, 300s, 450, 4013, 4014,
and lvp16
