Re: MIPS cross on Sun problems

[James Sandys-Lumsdaine]

Found the origin of the listed problems - my make wan't aliased to gmake as 
I thought it would be.  I also found an email saying to use --use-gnu-as and 
--use-gnu-ld.

However, I'm still struggling to get the thing to work.

What headers do I need, if any, for the --with-headers option? Do I pinch 
some SGI CC headers? Do I need to install gcc on an SGI Mips then pinch 
them?

I have tried using SunUnixgcc headers and SGI headers and the whole thing 
falls apart at:

Whatever is in /usr/include for the target platform you're building.
If it's an embedded platform, you'll probably need newlib.

MIPS cross on Sun problems

[James Sandys-Lumsdaine]

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
