Trouble compiling kernel

I'm having a bit of trouble trying to get the kernel to compile. In the NIOS II IDE, I right-click on the linux_kernel project and select "Build All."

The errors I get are not at all enlightening (at least not to me):

Using /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_1.4.0/linux-2.6.x as source for kernel

ln: creating symbolic link `include2/asm&#39; to `/cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_1.4.0/linux-2.6.x/include/asm-nios2nommu&#39;: File exists

I tried deleting /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_1.4.0/linux-2.6.x/include2/asm

but I still get the same error - it looks like make re-creates it via a sym link.

Any hints would be GREATLY appreciated.

    I uninstalled EVERYTHING - Quartus, NIOS II Dev Kit, and the uCLinux kit. I deleted everything I could find in the Windows registry related to Altera, NIOS, Quartus, cygwin, or uCLinux. Then I reinstalled everything again. But I still get the same error. My working space is on a network drive, and I wonder if /that/ could be the root of the problem?

    Perhaps. I moved everything to a local drive and that problem went away. After fighting through a couple more errors, I got stuck on this one:

    CC arch/nios2nommu/kernel/asm-offsets.s

    /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_1.4.0/linux-2.6.x/arch/nios2nommu/kernel/asm-offsets.c: In function `main&#39;:

    Help?
