Compiling uClinux OpenRISC port

While compiling uClinux today I succeeded with some source modifications.

ERROR:
/home/ant/project/or1k/uclinux/uClinux-2.0.x/include/asm/board.h:63: Error: junk at end of line, first unrecognized character is `/'
SOLUTION:
include/asm/board.h: only /* */ comments are allowed. // comments should be removed

ERROR:
head.S:231: Error: junk at end of line, first unrecognized character is `,'
SOLUTION:
arch/or32/kernel/head.S: remove last coma from the line 231: .section .romvec, "ax",

ERROR:
/home/ant/project/or1k/uclinux/uClinux-2.0.x/include/linux/skbuff.h:424: error: label at end of compound statement
SOLUTION:
in include/linux/skbuff.h, at the lines 423 and 410, add ; after head

ERROR:
sched.c:440: error: label at end of compound statement:
SOLUTION:
in kernel/sched.c, at line 439 add ; after case TASK_RUNNING:

ERROR:
tcp_input.c:2349: error: label at end of compound statement

make: *** [linux] Error 1
SOLUTION:

in arch/or32/board/rom.ld add entry for .rodata.str1.1 and .rodata.cst4 similar to that for .rodata. as follows:

.rodata.str1.1 :
{
*(.rodata.str1.1)
__etext = . ;
} > flash

.rodata.cst4 :
{
*(.rodata.cst4)
__etext = . ;
} > flash

With these modifications the application compiled and linked successfully.

Do you have a /or1k/uclibc ?
