I've succesfully build toolchains for ARM, the defalut is little endian.

binutils: #configure --target=arm-elf --prefix=/opt/armtools/ #make all install

#export PATH=/opt/armtools/bin: $PATH

gcc-newlib: #configure --target=arm-elf --with-gnu-as --with-gnu-ld --enable-threads --w ith-newlib --enable-languanges=c,c++ --prefix=/opt/armtools/ #make all install

I know I can use '-mbig-endian' to build the cource code for big endian target. But when do linking, it reported errors that the libraries are all little endian.

Does anybody know how to build Toolchains for ARM Big Endian?

Thanks

Hans

. Especially the guys at the CrossGCC list should be able to answer any question in that area.

Yup. The same toolchain can be used for big-endian as well. add a -mbig-endian to the command line.

In theory, you could mess with the configuration file to make big-endian the default, but why bother? You'd end up with a non-standard toolchain and regret it later.

In case he really, really wants to make big endian the default, this page might help:
