Workng with floating points on msp430 and code composer

I keep getting an error 

Can't find a source file at "/tmp/TI_MKLIBaXqLbT/SRC/mult32_f5hw.asm" while doing floating point calculations?

Am I actually missing files or an error in coding?

Thanks,

Carl

    'mult32' seems to indicate that this is the assembly file for 32 bit integer multiplication, and 'f5hw' likely indicates that the code is using the F5 family hardware multiplier. So it isn't related to float at all.

    Anyway, you should prvide a little bit more information, e.g. what MSP you are using, and what you're doing.

    The error alone just tells that the compiler seems to require a source file but cannot find it. Why and how is undeterminable by your problem description.

    That is the type of error that you see when you're stepping through a library function.  mult32_f5hw.asm is one of the source files from the msp430 rts library.  In a default installation, a zip of the library is located in C:\ti\ccsv5\tools\compiler\msp430_4.1.2\lib\rtssrc.zip.  Extract the contents if you wish to review the source.
