Re: [Harbour] undefined reference to 'hb_stack'

Sat, 30 Jan 2010 18:06:52 -0800 

I can't recommend doing that in any application as
these are not guaranteed interfaces/structures, plus
it may cause several other problems (alignment
dependence, corrupting VM internals, MT/ST mode
dependence, code breaking when Harbour internals
happen to change).


ok Viktor, I see. That's what happened indeed.


So my suggestion it to use the documented Harbour
C API. You can find these in hbapi*.h headers for
the most part.


Sure. Could you tell me how to do the following through the C API?

1) get the length of the array, instead of method below:

PHB_BASEARRAY pBaseArray = pArray->item.asArray.value;
ULONG ulLen = pBaseArray->ulLen ;


2) eval a codeblock with a member of the array as a parameter and get the 
return of the block, instead of the following:

HB_STACK_TLS_PRELOAD
hb_vmPushSymbol( &hb_symEval );
hb_vmPush( pBlock );
hb_vmPush( pBaseArray->pItems + ulPosition );
hb_vmPushLong( ulPosition );
hb_vmSend( 2 );
pItem = (PHB_ITEM) hb_stackReturnItem();

Thank you
Leandro

Hi,

Probably you try to use internals in your .c code.
(accessing HB_BASEARRAY f.e.)

I can't recommend doing that in any application as
these are not guaranteed interfaces/structures, plus
it may cause several other problems (alignment
dependence, corrupting VM internals, MT/ST mode
dependence, code breaking when Harbour internals
happen to change).

In fact not even Harbour RTL and other libs
except VM are allowed to use them.

So my suggestion it to use the documented Harbour
C API. You can find these in hbapi*.h headers for
the most part.

I guess most things can be solved with it; if not,
you may describe the situation and if justified
and doable we can add new API functions.

Brgds,
Viktor

After supressing hbvmopt.h I get a lot compile errors. This hb_arraySeek 
function is based upon hb_arrayScan and is quite similar to it and so it 
seems to need hbvmopt.h to be compiled.
Without hbvmopt.h I get the compile errors listed below and with 
hbvmopt.h the compile goes fine but the linkage doesn't work (undefined 
reference to 'hb_stack' error), but before the change to harbour 2.0 it 
was possible to compile the same code normally.

Any directions?
Thanks,
Leandro

Just delete '#include "hbvmopt.h"', it's an internal header, not needed.

Hi

Attempting to build a program with the function below I receive the 
following linkage error message:

undefined reference to `hb_stack'

The error is related to hb_retnint and hb_retni calls, because when I 
ommit them the error message goes away.

What is wrong with the code please?

Thank you
Leandro
