[Linux-ia64] Cant compile compiler

[Venkatesh Ramamurthy]

Hi,
when i compile the ia64 cross compiler , i seem to get error syaing that
cant include header stdlib.h and unistd.h in file gcc/ libgcc2.c . I
remember a special mention about these files in IDF . Can anyone point out
what i am missing?

TIA

You need to have IA-64 include files and IA-64 libraries to bootstrap
the compiler.  Install /usr/include and /usr/lib from the Trillian CD
somewhere on your system, install IA-64 kernel sources and make sure
your IA-64 /usr/include/{asm,linux} point to the IA-64 kernel headers.
After you've done this, configure gcc with

    ../src/configure --with-headers=/your/usr/include \
	--with-libs=/your/usr/lib --target=ia64-cygnus-linux \
	--program-prefix=ia64-cygnus-linux-

This should give you the cross compiler with all commands prefixed
with `ia64-cygnus-linux-'.

Any one to help me ...... 
All i wanted was to compile the cross-compiler ...... 
Did anyone attend IDF , where a special mention was given about those 2
files stdlib.h and unistd.h .....
Can anyone mail me the binary for the entire cross compiler ..... it would
be very nice if it could be done ......
As a driver developer , i feel it would be nice if didnt have to know the
intricacies of compiler development ..... Is this is all about Open Source
concept where one is given source code ... but doesnt compile ... sigh (
well it maybe my fault ...) .... 

Help will be appreciated ....
TIA

The IA-64 stuff (kernel,glibc,toolchain) is all still very bleeding edge.
If you are expecting things to work perfectly, then you will be very
disappointed.

Also, while the ultimate goal is a complete open source project, we are still
working on getting there.  Most of the work so far as been done under NDA,
and the NDAs just started lifting last week.  It will take some time to
transition from the closed development model that we have been using to the
open development model that linux and GNU developers are familiar with.
Meanwhile, things are going to be a little rough until this all gets
straightened out.
