make cross with egcs?

make cross with egcs?

[Jeff Johnson]

Hi --

I have
	egcs-1.0
	egcs-1.0.diff
	libg++-2.8.0b6.5
	binutils-2.8.1.0.18

and I want to do
	configure --host=i386-redhat-linux --target=sparc-redhat-linux
	make cross

I'm muddling my way through the cross faq.

First question:
	Do I need to apply the crossgcc-gcc-2.7.2.2 patch?

Second question:
	I tried "make cross" and got as far as making libgcc2 before
	missing alloca.h, stdlib.h & string.h. I snarfed these
	and stuffed them (with dependents) in gcc/include. Is this
	correct?

Last question:
	Retrying with added files, I get a signal 11. Now I'm stumped ...
	What to do?

Unlikely.

This indicates that you need target include files.

This indicates a bug in the compiler.  The cpp output along with the 
compile options & target name please :-)

I'm trying to make a egcs 1.0 under hpux with --target=m68k-linux. I
got the following error during 'make cross'

Is that because I haven't yet build an cross binutils and cross
assembler?

The as and compiler are the following:

>gcc --version
egcs-2.90.21 971202 (egcs-1.00 release)

The egcs was compiled with a previous egcs snapshot and then with
itself again.

May the Source be with you.

You need a cross assembler.  You'll also need other cross tools from
binutils.

I have binutils compiled with --target=m68k and have it installed in
/opt/share/cross. After that I restarted the make cross for egcs again 
and it went one a bit. After a short while it came up with missing
include file stdio.h. I tried to copy the include files from the glibc 
to /opt/share/cross/include and set the cross include directory in the
egcs Makefile. It then found the stdio.h, but it couldn't find any
iincludefile that was in a subdirectory (like sys/), whereas the sys
dir and the file was there.

Any idea whats wrong there? Shouldn't configure ask for the cross
includedirectory?

As you realized this indicates that the compiler isn't finding the
cross include files.

Are there actually any "sys" include files in /opt/share/cross/include?

There's options to set the cross include directory.  By default it
is $(libsubdir)/sys-include

/opt/share/cross/include/stdio.h (and others) exist, also
/opt/share/cross/include/sys/... exists, but thos aren't found
(stdio.h is found). It seems that it doesn't search in the
subdirectories for recursive includes.

The configure should check if they exist in the default path I would
think, but thanks for pointing out the option.
