help on a GPF situation

[Antonio Linares]

I am looking for a working example using __TracePrgCalls( .T. ) as per the docs:

* Once the tracing decribed below is turned on, you can call this
* in a PRG to trace PRG-level function calls:
*
* __TRACEPRGCALLS( <lOnOff> ) --> <lOldValue>
*
* It turns on|off tracing of PRG-level function and method calls.
* The symbol name is written just before it's called.
* This is very useful when debugging GPFs as it
* will trace all PRG-level calls up until the crash.
* Uses HB_TRACE so traces are in line with any C-level traces.

Is someone using it ? thanks

This may help many of us when a GPF suddenly happens

This is the story about what happened with this feature:

http://comments.gmane.org/gmane.comp.lang.xharbour.devel/2053

So, we have to rebuild hbvm.lib with -DHB_PRG_TRACE

[Antonio Linares]

How to build Harbour with this flag:

go.bat

Code: Select all  Expand view

set path=c:\bcc582\bin
set HB_USER_CFLAGS=-DHB_PRG_TRACE
win-make.exe

[Antonio Linares]

From our apps we have to do:

hb_TraceSysOut( .T. )
__TracePrgCalls( .T. )

[Antonio Linares]

And run DbWin to see the output:

Maestro en xHarbour me retorna esto error:

Error: Unresolved external '_HB_FUN_HB_TRACESYSOUT' referenced from C:

Que hacer?

Gracias, saludos.

João,

Puede ser que hb_TraceSysOut() sea una función de Harbour solamente. He revisado el código fuente de esas funciones en Harbour pero no las miré en xHarbour.

Prueba solo con __TracePrgCalls( .T. )

[karinha]

Maestro en xHarbour esto está correcto?

#define HB_TR_DEBUG 5

HB_TR_FLUSH=1
HB_TR_LEVEL=HB_TR_DEBUG
HB_TR_OUTPUT= "c:\trace.txt"

And in our code:

hb_tracestate(1)
__TracePrgCalls( .t. )

doesn't create c:\trace.txt anymore.

João,

gracias!

[Antonio Linares]

Joao,

Conseguiste que te funcionase hb_traceSysOut( .T. ) que envía los mensajes con OutputDebugString() ?

Debe hacer que la salida sea por DbWin32 (por DebugView parece que no funciona)

gracias por tu ayuda!
