Re: How to build big-endian arm libraries for the Intel XScale IXP425


Hello,

I managed to successfully rebuild the toolchain with the new patch(es)
as indicated by Jonathan Lamour. This time around

arm-elf-gcc --print-multi-lib gives me the following

[root@localhost bin]# ./arm-elf-gcc --print-multi-lib
.;
thumb;@mthumb
interwork;@mthumb-interwork
xscale;@mcpu=xscale
strongarm;@mcpu=strongarm1110
armv4t;@mcpu=arm9tdmi
be;@mbig-endian
xscale/be;@mcpu=xscale@mbig-endian
interwork/xscale;@mthumb-interwork@mcpu=xscale
interwork/armv4t;@mthumb-interwork@mcpu=arm9tdmi
interwork/be;@mthumb-interwork@mbig-endian
interwork/xscale/be;@mthumb-interwork@mcpu=xscale@mbig-endian
thumb/interwork;@mthumb@mthumb-interwork
thumb/xscale;@mthumb@mcpu=xscale
thumb/armv4t;@mthumb@mcpu=arm9tdmi
thumb/be;@mthumb@mbig-endian
thumb/xscale/be;@mthumb@mcpu=xscale@mbig-endian
thumb/interwork/xscale;@mthumb@mthumb-interwork@mcpu=xscale
thumb/interwork/armv4t;@mthumb@mthumb-interwork@mcpu=arm9tdmi
thumb/interwork/be;@mthumb@mthumb-interwork@mbig-endian
thumb/interwork/xscale/be;@mthumb@mthumb-interwork@mcpu=xscale@mbig-endian
[root@localhost bin]#


So I presume I've successfully built my big-endian toolchain

configtool does not complain about the toolchain and when I attempt to
build the "default" template for the IXDP425 board, I get the following
error message

sh -c "export PATH=/gnutools/arm-elf/bin:$PATH; unset GDBTK_LIBRARY;

Presumably, cc1 is the preprocessor?? Do I need to include some other
options to get support for -fno-rtti (which I presume means don't include
run-time type information) Any idea what I'm doing wrong
here?

Thanks in advance for any help

Krishna
