Error while buiilding in NiosII Eclipse EDS

[Altera_Forum]

Hi,  

I am trying to run a simple hello world application by using New Nios II Application and BSP from template option in NiosII EDS. After selecting my sopcinfo file, choosing my sample project (hello world) when I click on build project to generate my elf file, I get the following error :    alt_sys_init.c.text+0xb8): undefined reference to `__alt_invalid' collect2: error: ld returned 1 exit status make: *** [Test_on_actual_design.elf] Error 1   How can I solve this error?   Thanks.

Following, clean the project.  -Matt
