Problem of linker in HC12

pilou007 — Tue, 04 Sep 2012 22:12:26 GMT

Hi,

I'm a beginner in embedded system and I work on MM912J637, wich heart is a HC12.

Using code warrior to develop my program, I got trouble saying:

Link error : L1822: symbol _FSFLOAT in file......Fonction.c.o is undefined

Link error : L1822: symbol _FCMP in file......Fonction.c.o is undefined

Link error : L1822: symbol _FSTRUNC in file......Fonction.c.o is undefined

Link error : L1822: symbol _FSUB in file......Fonction.c.o is undefined

I got seven of these. And I for sure have the #include <hidef.h>.

I also have some warning like: ...LotOfFile.c.o has no DWARF debug info...

Could you help?

Thanks

Mentioned symbols are floating point runtime routines. You should start new project wizard again and specify that you want floating point enabled.

Hello,

Thanks for your answer.

I'va had some floating point operation, but I took them off everywhere in my program, now I only have some division on integer32, is that the problem?

How could I do some operation like division on integer without floating point?

Best regards

Disassemble your code and look for symbol in question, like _FSFLOAT or _FDIV. You should find that your code still is using floating point routines. Integer division runtime is always enabled and uses different set of routines.

Everything'ok now

Thank you very much
