MIPS cross on Sun problems

["James Sandys-Lumsdaine" <jas_sl at hotmail dot com>]

Hi all,

	I or my collegues have _never_ able to build a MIPS cross compiler on our 
Sun Sparc Solaris 2.6 workstations gcc-core-2.95.2. Any help would be 
greatly appreciated:

I am trying to build a mips-elf (or mips64-elf might do) cross compiler with 
the source so I can hack the source for a project of mine. I also have an 
SGI and x86 machine at my disposal if the Sun-Sparc-Solaris2.6 platform is a 
problem.

I am following the cross FAQ at 
http://www.objsw.com/CrossGCC/FAQ-4.html#ss4.1)

- Binutils installed and compiled succesfully
(pwd = ../build-binutils)
../binutils/configure --target=mips-elf --prefix=/work/jas/gcc/made 
--with-headers -v
make all install


Now I try to build the gcc-core-2.95.2 distribution:

../gcc-2.95.2/configure --target=mips-elf --prefix=/work/jas/gcc/made 
--with-headers -v
make all install

{
First problem is with the header dependencies for 
build-gcc/texinfo/makeinfo/  -
makeinfo.o: makeinfo.c ../lib/system.h ../config.h ../lib/getopt.h \
	makeinfo.h
multi.o: multi.c ../lib/system.h ../config.h makeinfo.h
}

Making all in makeinfo
make: Fatal error: Don't know how to make target `../lib/system.h'
Current working directory /work/jas/gcc/build-gcc/texinfo/makeinfo
*** Error code 1
make: Fatal error: Command failed for target `all-recursive'
Current working directory /work/jas/gcc/build-gcc/texinfo
*** Error code 1
make: Fatal error: Command failed for target `all-recursive-am'
Current working directory /work/jas/gcc/build-gcc/texinfo
*** Error code 1
make: Fatal error: Command failed for target `all-texinfo'

{
I side step the problem by commenting out the ../lib/xxx.h files
Compilation retried...
}

Can't see a workaround for this - am I close or simply rubbing up the wrong 
tree??

Thanks in  advance.
