Re: Compile erros when compling uCLinux for NIOS II

I get these series of errors when I run make in order to compile uCLinux for NIOS II.

Any input appreciated.

Ok maybe I'm just lucky but I've had no problems building the kernel using the external toolchain on two different Linux systems (fedora Core 13 and Kubuntu 10.04).

1. Download the 20090730 tarball and do the "./checkout" step from http://www.nioswiki.com/installnios2linux (http://www.nioswiki.com/installnios2linux)

2. Setup the prebuilt toolchain like http://www.nioswiki.com/operatingsystems/uclinux/binarytoolchain (http://www.nioswiki.com/operatingsystems/uclinux/binarytoolchain)

3. Build the kernel like http://www.nioswiki.com/operatingsystems/uclinux/uclinuxdist (http://www.nioswiki.com/operatingsystems/uclinux/uclinuxdist).

This has given me a kernel image pretty quickly.

Good luck, try following the wiki recipe above and if you get stuck, let me know where you get stuck.
