link error

Hi,

i have finished coding my Microcontroller and have compiled the code with a couple of 'possible loss of data' errors, which i knew would exist but have ignored it anyway.
when I tried to enter the debugger mode, i received many Link Errors, L1822. basically all the math symbols, such as pow, sin, cos, tan, as well as FMUL, FSFLOAT, FSUB etc, were said to be unidentifiable.

I have checked the threads,

and
http://forums.freescale.com/freescale/board/message?board.id=16BITCOMM&message.id=1914&query.id=50604#M1914, and have removed the -D__NO_FLOAT__ part, but I am still getting the error mesages.

What am I missing? How can I get rid of these error messages?
Your help is much appreciated!

The error messages you see mean that you are linking against the integer only library while using floating point operations.
Removing the -D option does not actually change much. The main change you have to do is to use the proper library, check the {Install}\lib\hc12c\readme.txt and also the threads you mentioned.
