CCS5 & MCSDK: Unresolved symbols at link time

David Aldrich

Other Parts Discussed in Thread: SYSBIOS

Hi

We are developing software for the 6670 dsp using CCS5 and the MCSDK (multi-core software development kit).  We are using the pdk component of MCSDK, in particular.

I have merged code from example: 'PA_emacExample_exampleProject' to my own project but am getting lots of unresolved symbol errors at link time, associated with the TI libraries.  What would be the correct way to fix these errors please?

David

    Hi,

    Just as with any undefined symbols linker error, the symbols shown are either defined in a library or in a source file that is missing from the project.

    In this particular case, the PA_emacExample_exampleProject has several library dependencies that are configured by the .cfg file, therefore you need to add the corresponding libraries to your existing project if the .cfg file does not include them for you. 

    If you build the original example project above, you can see all the libraries included in the file <linker.cmd> under the <Project directory>/Debug/configpkg/

    Hope this helps,

    Rafael
