question about the cross compiler's prefix by godspeed1989 on Dec 9, 2011			godspeed1989 Posts: 12 Joined: Sep 6, 2011 Last seen: Oct 3, 2012
The OR cross compiler's name is like "or32-XXX-gcc". The "XXX" can be linux or elf. What's difference between this two kinds of cross compiler? If I use or32-elf- can I compile the linux kernel?

I came across the same problem few days back, while trying to install the toolchain. or32-elf- is for bare metal programs, using newlib. or32-linux- is the one you need for making the kernel image. So install the uclibc toolchain. If you are doing it manually, first install or1ksim and then the toolchain.

So, What is difference between these two cross tools? ftp://ocuser:ocuser@openrisc.opencores.org/toolchain/or32-elf-linux-x86.tar.bz2 ftp://ocuser:ocuser@openrisc.opencores.org/toolchain/or32-elf-1.0rc1-x86.tar.bz2 What's the meaning of 'linux' in first tool name?

In later releases we started naming the ones which are cross compilers for OpenRISC Linux userspace as or32-linux-. I'm almost certain you should steer clear of that or32-elf-linux- one as it's very old, and should instead be using the tool chains that are being released more recently. Please refer to the GNU toolchain page on the OpenRISC project wiki for links to these.
