Gcc includes libraries that require access to the standard C library in
order to build.  You must provide the standard C library yourself
somehow.  You have not done this.

If you only want a compiler for building the kernel, then you don't need
any libraries.  In that case, you are already done.  What you have is
good enough to build a kernel.

If you need a complete gcc build, then you will need a C library.  If
you have access to a running ia64-linux system, the easy way to do this
is to copy the IA-64 linux /usr/include and /usr/lib to the x86 machine,
and then configure using --with-headers= and --with-libs= pointing at
the IA-64 header and library directories respectively.

An alternative method is to try to build gcc and glibc in parallel. 
This is not easy.  Offhand, I don't know how to do it, as I have never
tried to do this.

There is no such configure option.  The headers are required, and there
is no way to get around this.

The standard C library header files are missing.

You never said how this failed.  Your previous message was about a build
using the non-existent --without-header configure option.  Since I don't
know what error you got when you used --with-headers, I can't help you.

Why does this not work for IA-64?  A build procedure that works for
alpha-linux should also work for ia64-linux.

[Linux-ia64] Building IA-64 toolchain

[navin]

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

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

Have you tried NUE?  It's available here:

Yeah i have tried NUE.It is good and gcc is 2.95 something and glibc 
2.0. 
	I even tried copying the nue ia64-hp-something headers files and 
giving gcc the option with --header to that directory but it messed up as 
i previously mentioned

I don't know what the error is.Can you tell me where i can find the docs 
or how do i build the parallel glibc and gcc . It is nasty but it works.
I saw this on earlier lists other ports but hardly found the procedure.

The problem is that building an alpha target is easy .But when i apply 
the same rules to ia64 it breaks.GCC breaks.

I don't build cross-compilers myself anymore.  I suppose you could ask
the GCC folks for help.  Another option might be to get an account on
an ia64 machine (e.g., testdrive.hp.com).

Carlos has a very nice howto on this topic (for parisc-linux, but 
should work similarly for ia64-linux):

Na..This is not for kernel building. It for ia64 developemnt (C 
programs).

 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 --with-headers=/FPS/Bunny/work/nue/include 

I have copied /nue/usr/include and given that headers.make reports the 
following error.

Exactly / The build procedure should work for any target system.
Also in the previous case i didn't have to copy the header files.Maybe 
they are compatible with the standard  header files and this one is not.

The glibc copy you are using is too old.  This glibc will work with gcc
2.96 (sic), but it won't work with gcc 3.  There were related changes
made to glibc and gcc to enable unwind info to work correctly, which was
needed for C++ exception handling support.  Thus you can't use a new gcc
with an old glibc or vice versa.

David Mosberger mentioned testdrive.hp.com or something like that. 
Perhaps you could get an account there, and then get a newer copy of the
glibc header files from there.
