CCS/TIDC-EVSE-WIFI: linker error

Part Number: TIDC-EVSE-WIFI
Other Parts Discussed in Thread: MSP430F6736

Tool/software: Code Composer Studio

I got this error last step when it's linking:


cannot find file null: cannot find file
errors encountered during linking; "emeter-app-6736.out" not null: errors encountered during linking; "emeter-app-6736.out" not 

I have tried both V15 and V18 compiler, but results are same.

Please help. Thanks a lot.

    Jim,

    Could you capture the build output from the console and attach it to the thread.  Looks like the linker is expecting a filename with a particular option (maybe -l) but the filename is missing.

    You could also check the linker options here and see if there is an issue with any of the libraries being passed.  Perhaps a build variable, ${name} that is not valid?

    Regards,

    John

    John, 

    Thanks for replying. I have attached the script and path dialog below for your review.

    JD,

    Interesting that there are no -l commands in that list even though there are some specific in your build options.  

    In the linker options you have libmath.a specified twice.  Once with an absolute path to a location in an old CCSv6 installation and then a second time without a path.  The one without the path will use the search path at the bottom of the dialog to find the library.  I would remove the one that references the CCSv6 installation for a couple reasons 1) the library is specified twice 2) you don't really want to use an absolute path as then the project is not portable.

    I would also remove the quotes around "libmath.a" to be just libmath.a

    Regards,

    John
