linker error 'undefined ARTMPYU32U'

[stefat]

hi all,

I am a rookie with CW and I am getting the linker error as per the subject just due to the following line(s) of code:

uint32_t ulvar;

...

ulvar = 3*ulvar;

After some investigations I found this same linker error glows (only) whenever attempting to do an integer multiply (between integer and/or long integer vars)

Is some include or library file missing ?

I tried some libraries (inttypes.h, math.h) with no success. I do not find ''ARTMPYU232" function in any file.

Is there anyone who can help ?

Thank you and regards

Stefano

Hello

Which CPU are you targeting (HC08, HC12, Coldfire, EPPC, ...)?

It looks like you need to add some library file to your project. Name of the library file to add depends on the CPU you are targeting and on CodeWarrior version.

  To retrieve that info:
    - Start CodeWarrior
    - Select Help -> About Freescale CodeWarrior
    - Click on "Install Products"
    - CodeWarrior version used is displayed on top in the Installed Products dialog.

Also in order to avoid this kind of trouble I would highly recommend you to create your project using the CodeWarrior project wizard or a valid stationery for your board.

Creating your project from a stationery should prevent that from happening.

hello CrasyCat,

I fixed the problem * ... cheers..... and thank you.

I copied a new design from my first one (leaving ALL support lib files in () )... and linker (obviously) finds the referenced function.....

Sorry for my...rookieness.

By the way: I recall now the reason I cancelled all SUPPORT lib's: because the generated code was 54K .. instead of the few - expected - Kbytes. This takes to my consequent question:

See please the attached CW design: it is the new one running.

How big is the code ? 54K or few K's as in the right .xmap file ?

I would appreciate much your kind answer

Thanks again and regards

Hello

In fact you should not care about the size specified in the .mcp window. The real application code and data size is stored in the .map file.

The size specified in the .mcp window are size before dead stripping (i.e that would be the size in case your application would use all the functions defined in the run time library).

The linker is performing dead stripping per default. That means only the objects (functions, variables) really used in the application are linked to the application. Information written to the .map file are code and data size after dead stripping.

That is the actual application size.

I hope this helps.
