trying to compile uClibc for openrisc or32

[Chan Kim]

I figured gcc was including some other files maybe so I added -nostdinc so that gcc doesn't use standard include path. 
make PREFIX=${SYSROOT} -nostdinc
That made it work.

Hello,
Here are some added explanation of my situation.

The file causing error, ./libpthread/linuxthreads.old/sysdeps/or32/pt-machine.h includes
and and the only place I can find those files is
~/openrisc/toolchain/uClibc which is the directory I'm compiling uClibc at.
I previously installed linux headers with INSTALL_HDR_PATH=${SYSROOT}/usr
but there I can't find features.h or sys/syscall.h under ${SYSROOT}/usr.
1. am I supposed to use the linux header in ${SYSROOT}/usr ? 
I see some header files under ${SYSROOT}/usr/include. (from there under linux, asm, asm-generic, uapi, video,...)
But I can't see any file features.h and sys/syscall.h .. what's gone wrong?
2. or should I use files under uClibc/include?

Any help will be greatly appreciated. I don't know what's wrong..
Thanks!

Chan

Hello,
I have a problem that I think I could get some answers to from this email list.
Recently I was following http://openrisc.net/toolchain-build.html to build gcc toolchain for openrisc or32. (to understand gcc build procedure)
I'm doing 'building by hand' flow in the page and had passed
binutils 
stage 1 gcc 
install linux headers 
and was doing 'compile uClibc' where I got an error.
The 'compile uClibc' stage is composed of commands below.

$ git clone git://openrisc.net/jonas/uClibc 
$ cd uClibc 
$ make ARCH=or32 defconfig 
$ make PREFIX=${SYSROOT} <--- here I get error below
$ make PREFIX=${SYSROOT} install

when I run 'make ARCH=or32 defconfig', I get this error.

----------------------------------------------------------------------
Has anybody had same problem before? I use CentOS 6.4, and am running the make command under uClibc directory.
The $SYSROOT value is /home/ckim/openrisc/toolchain/or32-linux/sys-root. 
Any help will be appreciated.
Thanks!
