Compiling Linux Kernel

Hi folks,

Solving one problem, leads to new problems...

An error occurde while compiling my linux kernel. (Still working with the quick start guide PDF) http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/rolleyes.gif

Here the message: 

Error    error: `na_ide_ide&#39; undeclared (first use in this function)  line 218
Error    error: (Each undeclared identifier is reported only once  line 218

Is this because of a wrong kernel configuration (but I used the default settings as described in the tutorial) or is it a bug?

Thanks

    Hi User,

    This error occurs because the Compact Flash component is not present in your SOPC Builder design. The .sof/.ptf supplied with the distribution (c:\altera\kits\nios2\examples\verilog\<board name>\linux\linux_time_limited.sof and linux_<board_name>.ptf) contain this component; reference designs like "full_featured" do not.

    You can disable the IDE options in the kernel to get past this point...
