[Linux-ia64] Building IA-64 toolchain

[navin <navin@students.iiit.net>]

Hi,
	I am doing a project on compilers.I have to build gcc for ia64.I 
did build the binutils .In that case i didn't get any compilation errors.

HOSTMACHINE=i386 pentium
TARGETMACHINE=ia64

 Next i had to build gcc (source gcc-3.2) for ia64. I configured 
it with the following option 
CFLAGS="-O2 -Dinhibit_libc" ../gcc-3.2/configure 
--target=ia64-unknown-linux --prefix=/FPS/Bunny/work/ia64.bak 
--enable-languages=c --disable-shared --disable-multilib 
--enable-threads=single --without-headers
and with a lot of other options like removing the --without-headers part 
and another time adding other options with-headers=asm-ia64 (kernel 
sources) . Every time i get  error saying 

if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi

I also referred to many cross GCC faq and howto's but no help .The error 
still pops up.

Also from some of the previous posts i found that if i am building on a 
pentium or some other machine there is a trick involved.Andreas Jaegar 
told me that i had to install-headers before compiling the bootstrap 
gcc.He said to contact you guys as i don't have the headers for ia64.I 
have the sources for kernel which contain asm-ia64 and glibc-2.3.I don't 
know how to avoid the error.


Thank You
