    This is an odd problem. You've obviously got a uart in the system. alt_sys_init.c generated code in it to initialize the UART but it can't find a MACRO definition that it expects. Look in your "system.h" file to see if the macro "UART1_IRQ_INTERRUPT_CONTROLLER_ID" indeed does or does not exist.

    Did you make changes to your system recently. Have you tried a "Clean Project" of both your project and system library before rebuilding?

    Your SoPC system must have a component called UART1 in it. It's very odd that it's getting added to the alt_sys_init but not to system.h. Did you try cleaning the project. None of the project's files are accidentally write-protected are they?
