problems compiling gcc-4.2.2 with or32-elf target

[Gijs Molenaar-3]

Hi,

Please correct me if I'm wrong, I'm quite new to embedded programming
and even C programming, but I'm trying the best I can. I have a Jennic
JN5139 set, which includes a IDE and toolchain for windows only. But I
want to get the toolchain running under linux.

On the Jennic forum there is a link to this page:
http://www.zubira.com/openrisc/or1k_gcc3_4_4_bu2_11_93.html

But the source files are not available anymore, and the owner is
unreachable. After some googling and trying out I stumbled upon
opencores, which maintains the or32 toolchain. I downloaded or1k
toolchain, and started compiling binutils and gcc. But with GCC I
encountered some problems.

My GCC doesn't support -Wno-overlength-strings but somehow the configure
scripts thinks it does. I removed all no-overlength-strings statements
from the configure script, and now it compiles. Maybe this is a bug, or
maybe my error, I don't know.

The next problem I have, and this one I can't solve, is this:

/home/gijs/Stuff/or1k-tools/build/b-gcc/./gcc/xgcc

So hereby I report a bug :) I tried to search the mailingarchives, but I
couldnt figure out if this was posted before.

My Linux distribution is Ubuntu 8.10, I tried GCC 4.1 and 4.3. My
configure statement is:

../gcc-4.2.2/configure --target=or32-elf --prefix=/usr/local/or32-elf
--enable-languages=c,c++ --with-gnu-as --with-gnu-ld --with-newlib
--with-gxx-include-dir=/usr/local/or32-elf/or32-elf/include

Anyone has a idea?

Thanks,

 - Gijs

Hi Gijs,

I'll address your technical issue below, but first some general comment.

Whoever supplied your GCC compiler is obliged to supply you with the
source code. You should tell them that the link is broken, and request
that they supply you with the GCC source. Most companies understand this
and are quick to fix the problem.

The Free Software Foundation provides advice on how to deal with GPL
license problems.

        http://www.fsf.org/licensing/licenses/gpl-violation.html

I don't understand your comment about GCC not supporting
-Wno-overlength-strings. Could you explain further. Editing the GCC
configure script is almost certain to end in disaster!

I don't believe the target "or32-elf" has been tested recently. The only
target I know is valid is "or32-uclinux". However this is an ELF target,
so should be suitable for you.

How well the compiled code will work depends on how close the JN5139 is
to a standard OR1200 core. Since the OR1200 core is licensed under the
LGPL, you should be able to get the source code of the processor core
(but not anything else) from your JN5139 supplier and compare it.

You may find the following application note helpful:

try using --target =or32-uclinux --disable -checking option with configure..it might help...
