Re: [openrisc] or32-uclinux, or32-uclibc and or1ksim

Hi Maunal,

First I will tell you, that you should build the tool chain like it is
described on
http://www.opencores.org/projects/or1k/GNU%20Toolchain%20Port. That
means that not only that you have to build and install binutils and gcc
package, but also uClibc (and because of that you will have to download
and at least configure uClinux). Please, follow the instructions
exactly. After that, you will get good compiler for compiling both,
stand-alone and uclinux applications and also, you will be able to
compile testbench and you will see that it works.

Where did you get basic.s, in the testbench folder there is basic.S (gcc
will recognize *.S as assembler file but not *.s). But this will not
compile either, because you told the compiler to build executable for
its target (in that case uClinux). It will try to include all sorts of
things beside your code (initialization of stdio, preparation for start
and exit, ...). It tries to find this in the crt0.o and libc library,
but because you haven't installed it, will fail. You want to build
stand-alone application, so do like this (even if you don't have uClibc
installed, because you will tell the compiler exactly what to do, and it
will obey):

[simons@odin testbench]$ or32-uclinux-gcc -I./support -c basic.S -o
basic.o
[simons@odin testbench]$ or32-uclinux-gcc -nostdlib -o basic
-T.//default.ld basic.o

Try to run it on the simulator:

[simons@odin testbench]$ or32-uclinux-sim -f default.cfg basic

It is serching for libc library, which you didn't install.

*.S/*.s problem.

Yes, there is me :)
