    Hello,
    This is a common linker error. It is documented in detail in the below link:
    processors.wiki.ti.com/.../10234

    Basically you need to include the object file(s) that have the undefined symbols (P4DIR, P4IN, P4OUT) defined. This is something application specific so it is something you need to determine yourself (though if you are compiling a TI example, the experts in the MSP forum may be able to provide some more suggestions)

    Thanks
