I have never used debugging, even with just Clipper, but now I feel the need to.

How do I step through the program to see where I am going wrong.

Ollie,

The debugger is built into [x]Harbour, and it looks and behaves as the Clipper one. In order to use it you have to compile your PRG using /b. If you are using samples\buildh.bat then do:

buildh.bat myapp /b

In your PRG you have to add these lines:

Code: Select all

function Main()

   AltD( 1 )   // Enables the debugger. Press F5 to go

   MsgInfo( "debugger enabled" )

   AltD()      // Invokes the debugger

   MsgInfo( "debugger invoked" )

return nil

Now when I compile I get

Unresolved external 'HB_FUN_ALTD' referenced from ...

How do I resolve this?

Posted: **Mon Jan 01, 2007 9:56 am**

Ollie,

You have to link Harbour's debug.lib

Posted: **Mon Jan 01, 2007 1:23 pm**

Ok, did that. But when I add the /b switch it complaints about all kinds of Unresolved Externals (e.g. _HB_FUN_RELEASEWINDOW) from MIDLEX2.LIB (Without the switch it compiles, but of course to debug info)

(I am using XMATE)

And by the way, how would I have found out to link debug.lib without your help - there must be a way I could have found that out. And where does one find out what functions are in the LIB (any LIB for that matter) and how to use them etc.

Posted: **Mon Jan 01, 2007 3:08 pm**

Ok, ignore last message. I configured XMATE exactly like buildx.bat and now it compiles - /b and all.

I added:
PROCEDURE debugger()
AltD( 1 ) // Enables the debugger. Press F5 to go
MsgInfo( "debugger enabled" )
AltD() // Invokes the debugger
MsgInfo( "debugger invoked" )
RETURN

and I run this PROCEDURE on a button. I see the "debugger enabled" box, but never thee the "debugger invoked" one and the program 'stops responding'

Ollie,

Ops, you need to link GTWIN.lib instead of GTGUI.lib to use the debugger.

The debugger is a [x]Harbour feature, thats why its not explained in FWH docs, and also it may change or get modified in the future (there are plans to rewrite it in pure C without using PRG to improve its speed).

Posted: **Mon Jan 01, 2007 8:31 pm**

Replaced the GTWIN.LIB with GTGUI.LIB, but then:

Error description: Error BASE/1131 Bound error: array dimension

Line 19 of Main is the first line of code and is simply a LOCAL variable declaration:

LOCAL oIcon, oMain_Toolbar

Something else is wrong.

Hello Ollie,

Did you ever get the debugger working with Harbour? I'm having the same problem you had -- the example program \FWH\Samples\Altd.prg get's as far as the first message, "Debugger Enabled", but the Altd() call seems to lock it up. Certainly no other windows appear. I took care to compile with the /b option, and I used:

%bcdir%\bin\ilink32 -Tpe -s @b32.bc

in the BuildH.bat file as instructed. I'm linking in Debug.lib.

Thanks!

-Patrick

Hi Patrick,

Alas, I did not.

Posted: **Sat Apr 21, 2007 9:31 pm**

Okay thanks for letting me know. I wrote an email to Antonio about this, so hopefully we should at least be able to get the sample program Altd.prg working, and we can go from there.

Great. Good luck, please copy me.

Thanks

Posted: **Sun Apr 22, 2007 5:26 am**

Patrick, Ollie,

If you use samples\buildh.bat to test it then you have to modify it to use GTWIN.lib instead of GTGUI.lib, add debug.lib and remove -aa when linking. And invoke buildh.bat this way:

c:\fwh\samples\buildh.bat altd /b

Here it is working fine:

Here you have gtwin.lib and debug.lib just in case yours are not the right ones:

Antonio,

Still no luck I'm afraid. When I try and build altd.prg I get these errors:
