    I tried changing the I/O Library Name to debug in my project's Debug properties, but I still get the same error. Is there some other setting that need to be changed or a definition that needs to be set?

    Do you have "Enable Unused Symbol Removal" set to be "No" - if so then the C library will require __putchar to be defined even if it isn't used. We'll fix/workaround this in the next release.
