[quote user="Stephen Phillips1"]Hmm I see so this is more a code composer studio issue then? I'll check CCS path settings (if their are any ,,, hmmm)[/quote]
Are you building for MSP430? I see a libmath.a in \ccsv5\ccs_base\msp430\lib within the CCS installation directory. If that is the one you need, make sure that directory is in your linker search path (Project Properties->Linker->File Search Path).
