HC12 Linking Error

Joxer — Wed, 31 Jan 2007 00:11:42 GMT

I am not sure if this error is the same as the sprintf error that needed to add the datapage.c file. I tried that but with no success and received other errors so I removed the file.

Things to know:

1.) My project is called Test

2.) I added a FreeCntr32 Bean as I need some timing functions

3.) I copied and pasted the example code from the typical usage code into the main function

4.) When I debug the code I get these linking errors

Link Error : L1822: Symbol _DUFLOAT in file C:\. . . \Monitor\ObjectCode\Test.c.o is undefined

Link Error : L1822: Symbol _DCMP_RC in file C:\. . .\Monitor\ObjectCode\Test.c.o is undefined

5.) I am very new to CodeWarrior so be gentle

These are integer to floating point conversion runtime routines,
you have to link against a ansi library which contains the floating point support. See lib\hc12c\readme.txt for the list.
Also as you seem to use only the integer to float conversion and the float compare, but no actual float operation, I wonder if the code could be written with integer arithmetic only.

I added the library ansis.lib and that seemed to clear up the problem. Thank you for pointing me to the Readme.txt file, I would have never found it or thought to look in there for the information.

I also took your advice and changed it to integer math rather than keeping it in floating point.

Ok, adding the library only allowed me to compile and debug once. After that initial time, it gives me the same error. I have tried all the libraries on the list in the Readme and none of them seem to clear up the linking error.
