Eclipse for Nios II Unrecognized Func Def - Eclipse for Nios II Unrecognized Func Def Hello, The problem and steps I've taken is outlined in the following post: https://forums.freertos.org/t/definitions-port-c-alt-ic-irq-disable-enable/18579 Despite this being a topic in a previous discussion board ( https://community.intel.com/t5/Intel-Quartus-Prime-Software/Why-I-can-not-find-the-alt-irq-enable-function-in-HAL-src/td-p/174843 ) the fix applied does not work for me. The program is simply the standard FreeRTOS build and although the function definition is there, the compiler keeps giving me a makefile 1033 error and "undefined reference to alt_ic_irq_enable/disable" errors. And the definition is in a file that's been included. I'm not sure where to go from here to further troubleshoot the issue. Thanks in advance!
