Question about nios ii interrupt registration

Honored Contributor I

Hi everyone  



i`m try to develop interrupt handle method in my software running in uClinux. 


When i tries to compile alt_irq_register.c, there is error "undefined reference to 'alt_irq_active'". 


I uses "nios2-linux-gnu-gcc -Iinc -o alt_irq_register.o alt_irq_register.c alt_irq_handler.c" command to compile. 


alt_irq_active is defined in alt_irq_disable() function which is defined at alt_legacy_irq.h file. 


And alt_irq_register includes alt_legacy_irq.h file, but undefined reference error occurs. 


How can i solves this problem. 


Thank you!
