programmers. DEC FUSE offers a set of tools with a DEC OSF/Motif user

interface and graphics options in an integrated setting. DEC FUSE tools

include an editor, a code manager, a program builder, a debugger, a

cross-referencer, and a call graph browser.

DIGITAL UNIX systems also include another debugging tool, kdbx. The

kdbx utility is an interactive, crash analysis and kernel debugging tool that

replaces the ULTRIX crash program. As a kernel debugging tool, kdbx

serves as a front end to the dbx debugger, and enables you to examine the

running kernel or dump ﬁles created by savecore. The kdbx utility is also

insensitive to version numbers, and can be customized and extended. For

more information on the kdbx utility, see the Kernel Debugging manual.

6.3.5 Other Programming Tools

DIGITAL UNIX systems have other programming tools that are available

on ULTRIX. These tools have been modiﬁed to support the ANSI C

language dialect, shared libraries, and 64-bit data types. Otherwise, their

use is the same as their ULTRIX equivalents.

The following list gives a brief description of each tool. (For more

information about the tools, see the reference page for each individual tool.)

• ar

Creates and maintains archive libraries. (You cannot use the ar

command to create shared libraries. To create shared libraries, use the

ld command as described in Section 8.1.4 and Section 8.1.5.)

• cflow

Analyzes C application ﬁles (as well as yacc, lex, and assembler ﬁles)

and builds a graph that charts the external references made in the

application.

• ctags

Creates a tags ﬁle that you can use with the ex editor. The tags ﬁle

speciﬁes the location of functions and typedef declarations in the

speciﬁed set of C application ﬁles.

• cxref

Analyzes a set of C application ﬁles and builds a cross-reference table.

The table lists all the symbols used in the application.

• dis

Disassembles object ﬁles into machine instructions.
