Thanks for the help but I'm only getting more and more errors.

Please add -D name option switches like

nios2-linux-uclibc-gcc -c  -D __ASSEMBLY__ -D __KERNEL__ -I/home/developer/altera/nios2-linux/linux-2.6/include -I/home/developer/altera/nios2-linux/linux-2.6/arch/nios2/include -I/home/developer/altera/nios2-linux/uClinux-dist/linux-2.6.x/include /home/developer/altera/nios2-linux/linux-2.6/arch/nios2/kernel/entry.S

.

Some include files are used as mixed C and assembly codes. So there is the# ifndef __ASSEMBLY__ macro like

 14# define _ASM_NIOS2_PTRACE_H
 15 
 16# include <uapi/asm/ptrace.h>
 17 
 18 /* This struct defines the way the registers are stored on the
 19    stack during a system call.  */
 20 
 21# ifndef __ASSEMBLY__
 22 struct pt_regs {
 23         unsigned long  r8;      /* r8-r15 Caller-saved GP registers */
 24         unsigned long  r9;
 25         unsigned long  r10;
 26         unsigned long  r11;
 27         unsigned long  r12;
 28         unsigned long  r13;
