Use malloc in CodeWarrior for HC08 : "out of allocation space in segment.."

[ppoi]

I followed the instruction of the FAQ-27441 "Can I use malloc in CodeWarrior for HC(S)08?".
However I have an error of link "out of allocation space in segment HEAP_SEGMENT at adress 341".
Could you provide me a simple project without error. I need really to dynamically allocate memory in my project...

here the modifications brings to the project,

//----------------------------------------------------------------------
Modification of the file "libdefs.h"

#define LIBDEF_HEAPSIZE 20 // by default 2000

//----------------------------------------------------------------------

Here my file ".prm" :

SECTIONS
    ...
    RAM1 = READ_WRITE       0x0050 TO 0x0340;
    DG_HEAP  = READ_WRITE   0x0341 TO 0x044F;
       RAM2 = READ_WRITE       0x0A00 TO 0x0BFF;

PLACEMENT
    ...
    HEAP_SEGMENT                  INTO  DG_HEAP;
    SSTACK                        INTO  STK_AREA;

END

//----------------------------------------------------------------------

Development tool:

Version of CodeWarrior IDE 4.1 "Build 0669"

It's good, everything works well

thank you very much BlackNight

My CodeWarrior is too old for the utilization of 'Pack&Go'

My project,

TestHeap.zip

Hello,
ok, it is always better to do it with an example than just suggesting things out of my mind :smileyhappy:.
As I'm having a newer CodeWarrior (and the project got converted), I just have made some screen-shots so you can do the modifications on your end. Please see attached document.
In essence: you need to add as well the heap.c locally to your project (sorry, I have missed that heap_ is defined in there).
See as well the instructions and hints in the document (which hopefully will work for you too, it did for me).

Regards,
BK

hello,

I carried out handling of BlackNight
I you joint of the images of my project (see .zip)
Can you look at the project ?
thank you to tell me my errors

I desperate because I followed the instructions...

Hello,
from the picture you have attached it looks like you have a LIBDEF_HEAPSIZE defined to 20?
I guess this is your problem?

Otherwise can you zip your project (you can use the 'Pack&Go' wizard in the CW Help menu for this.

Hi,

In the project “hc08_lib.mcp”,
1) I have modify only the file “libdefs.h”
2) The configuration of the project is as follows,
   Target setting -> Target Name : all Libraries
   Linker : None
   Pre-Linker : None
   Post-Linker : None
3) Make (F7) -> It's ok
4) From {Install}\lib\HC08c\hc08_lib_Data -> new files ".o"

In my project,
1) The libs is “ansi.lib” (only)
2) I see from {Install}\lib\HC08c\lib
   There are the files "ansi.lib", "ansi.lst", "ansif.lib"...
   the dates of the files are 2000
3) The configuration of the project is as follows,
   Target setting -> Target Name : LAUTERBACH
   Linker : Linker for HC08
   Pre-Linker : None
   Post-Linker : None
4) Target -> Access Path : "{compiler}\lib\HC08c\lib"

I think that I must generate the new file “ansi.lib”.     
I don't know the procedure...

There is also in the repertory "{Install}\lib\HC08c\lib.e20" the file “ansi.lib” ?


thank you for the assistance

[BlackNight]

Hello,
instead of compiling the whole ansi library, you could simply add malloc.c and libdefs.h (modified) into your project. Make sure that it compiles the malloc.h with the right libdefs (increased heap size).
If malloc.o is linked (first) in your link order, you should get what you want.

Version of “codewarrior” : 1993-2000, yes it is really old...

I followed the procedure of the FAQ-27441,

1) Open project hc08_lib.mcp from {Install}\lib\hc08c directory.
2) Edit file libdefs.h (from {Install}lib\hc08c\include directory.
3) Change the LIBDEF_HEAPSIZE to something smaller.
4) Save the changes.
5) Rebuild the libraries (or at least the one you need). => Push F7, I see the new files "ObjetCode" in the repertory "hc08_lib_Data"

How to generate the file “ansi.lib”? it is my error, I think

[CrasyCat]

Hello

What is the current build target name displayed in the .mcp window combo box?

If you open the Target setting dialog for the ANSI library project and look at eh librarian for HC08 panel, what is the name of the .lib file there?

Which library file are you linking to your application?

When you pressed F7, did something happen in CodeWarrior?

The procedure described in the FAQ has been validated with CW for HC08 V3.1 and later.

Hello

The version number you are providing does not help a lot. Anyway, from the IDE version number it looks like you are using a VERY OLD version of CodeWarrior.

It might be a good idea to upgrade to something more recent.

Then after you have changed the LIBDEF_HEAPSIZE, did you rebuild  the ANSI libraries?

All of them? Only one? Did you rebuild the one that is linked to your project?
