alt_irq_init

[Altera_Forum]

There is an annoying error message when I try to compile my project in NIOS IDE. I am using quartus 9.0 (sp2). I build a project with SOPC builder and when I try to compile the C code I see the follwoing error: 

Linking myproject.elf... <project folder>/myprojct_syslib/Release/myproject_syslib.a(alt_main.o)(.text+0xc): In function `alt_main': <quartus 9.0 installed fodler>/nios2eds/components/altera_hal/HAL/src/alt_main.c:102: undefined reference to `alt_irq_init' collect2: ld returned 1 exit status make: *** [myproject.elf] Error 1 Build completed in 17.187 seconds  There is a forum that user has similar issue but the solution is removing ".a" file and cleaning the project! For sure solution does not work! Sometimes I restarted my computer and error will be gone! sometimes I rebuild the hardware in sopc builder and the error will be gone. Has anyone seen this before? -Amir

If I recall, there were issues with the version of Eclipse included in versions this old. Be sure to clean and re-build your main C project at minimum and, if that doesn't work...your BSP/syslib as well.

Thanks Slacker for the reply! I think my problem was related to diffrenet versions of Quartus! I build my design in sopc builder and compile c code both in version 9.0. For compilation I always use of Quartus 10. After compilation is done I need to open qpf file in 9.0 before running nios IDE otherwise i get the error that I mentioned in the thread!

My problem was related to different version of Quartus. I generated a SOPC build with Quartus version 9 and compiled the RTL with version 10. after for running the Quartus version 10, if I want to run NIOS IDE i need to open qpf file in Quartus 9 and then compile NIOS IDE
