1.$ FORTRAN/DEBUG/NOOPTIMIZE WIDGET
$ LINK/DEBUG WIDGET
$ RUN WIDGET
[ Debugger Banner and Version ]
%DEBUG-I-INITIAL, language is FORTRAN, module set to WIDGET
DBG>
The FORTRAN and LINK commands both specify the /DEBUG qualifier
to compile the program WIDGET.FOR with debugger symbol table
information. Because the program has been compiled and linked
with debug information, the debugger is automatically invoked
by the image activator upon starting the program with the
RUN command. No program code has yet been executed when the
debugger is invoked.
2.$ FORTRAN/DEBUG/NOOPTIMIZE WIDGET
$ LINK/DEBUG WIDGET
$ RUN/NODEBUG WIDGET
NAME:
NAME:
NAME:
^Y
$ DEBUG/RESUME
[ Debugger Banner and Version ]
%DEBUG-I-INITIAL, language is FORTRAN, module set to WIDGET
DBG>
The FORTRAN and LINK commands both specify the /DEBUG qualifier
to compile the program WIDGET.FOR with debugger symbol table
information. The RUN command begins execution of the image
WIDGET.EXE, which loops uncontrollably. Ctrl/Y interrupts the
program, and the DEBUG/RESUME command gives control to the
debugger.
3.$ CC/DEBUG/NOOPTIMIZE ECHOARGS
$ LINK/DEBUG ECHOARGS
$ ECHO == "$ sys$disk:[]echoargs.exe"
$ DEBUG/KEEP
[ Debugger Banner and Version ]
DBG> RUN/COMMAND="ECHO"/ARGUMENTS="fa sol la mi"
%DEBUG-I-INITIAL, language is C, module set to ECHOARGS
%DEBUG-I-NOTATMAIN, type GO to get to start of main program
DBG>
.
.
.
DBG> RERUN/ARGUMENTS="fee fii foo fum"
%DEBUG-I-INITIAL, language is C, module set to ECHOARGS
%DEBUG-I-NOTATMAIN, type GO to get to start of main program
DBG>
.
.
.
DBG> RUN/ARGUMENTS="a b c" ECHOARGS
%DEBUG-I-INITIAL, language is C, module set to ECHOARGS
%DEBUG-I-NOTATMAIN, type GO to get to start of main program
DBG>
The CC and LINK commands both specify the /DEBUG qualifier
to compile the program ECHOARGS.C with debugger symbol table
information.
The symbol definition command defines a foreign command for use
during the debugging session.
The DEBUG/KEEP command invokes the kept debugger.
The first RUN command uses the /COMMAND qualifier to specify
a foreign command to invoke the image file and the /ARGUMENTS
qualifier to specify a string of arguments.
The RERUN command reinvokes the same image file and uses the
/ARGUMENTS qualifier to specify a new string of arguments.
The second RUN command specifies a new image file and a new
string of arguments.
On Integrity server systems, start the Heap Analyzer within the
kept debugger:
4.$ debug/keep
DBG> run/heap 8queens
or, alternately:
5.$ debug/keep
DBG> run 8queens
.
.
.
DBG> deactivate break/all
DBG> deactivate watch/all
DBG> deactivate trace/all
DBG> start heap_analyzer
DBG> activate break/all
DBG> activate watch/all
DBG> activate trace/all
Using this method, you must first deactivate all watchpoints,
breakpoints, and tracepoints before starting the heap analyzer
with the START HEAP_ANALYZER command. This procedure prevents
a potential race condition from occurring. After starting the
heap analyzer, re-activate the breakpoints, watchpoints, and
trace points.
On Alpha systems, start the Heap Analyzer within the kept
debugger:
6.$ debug/keep
DBG> run/heap 8queens
7.$ DEBUG/SERVER=(PROTOCOLS=(TCP_IP,DECNET))
%DEBUG-I-SPEAK: TCP/IP: YES, DECnet: YES, UDP: NO
%DEBUG-I-WATCH: Network Binding: ncacn_ip_tcp:16.32.16.25[1112]
%DEBUG-I-WATCH: Network Binding: ncacn_dnet_nsp:63.1004[RPC20A020DD0001]
%DEBUG-I-AWAIT: Ready for client connection...
The DEBUG/SERVER command establishes a connection to the debug
server, requesting network protocols TCP/IP and DECnet. Note
that the binding strings are saved in file TEMP.TMP. You can
use the TYPE command to display the contents of TEMP.TMP.
