I'm trying to set up OpenRISC GNU tool chain on Red Hat Enterprise Linux Server release 6.3 (Santiago) and my question is that the tool chain file "or32-elf-1.0rc1-x86.tar.bz2" does it work on 64 bit Linux. since i'm getting an error "Segmentation fault (core dumped)"

If not then should i install the tool chain on Linux 32 bit version?

Please suggest me the steps to install the complete tool chain with library files on Linux OS 32/64 bit.

Hi Chetan,

I'm not sure where you got that particular version from. However the stable GCC 4.5.1 tool chain in Subversion should build OK on 64-bit. If not, post a message.

You can find details of how to build this here:

http://opencores.org/or1k/OpenRISC_GNU_tool_chain#Installation_from_source

There is a newer, development version, of the tool chain available, described lower down on the same page. I would expect this to build on 64-bit as well, but if you have problems, please post a message.

HTH,

Jeremy

Thanks for the reply, I had downloaded the file or32-elf-1.0rc1-x86.tar.bz2 from this link

http://www.rte.se/blog/blogg-modesty-corex/openrisc-1200-soft-processor and the FTP Link for the file is

ftp://ocuser:ocuser@openrisc.opencores.org/toolchain/or32-elf-1.0rc1-x86.tar.bz2

I'm trying to understand the installation setup and steps please read the below installation steps and guide me if I'm doing any wrong steps or missing any steps. Please Note: My requirement is to step up OpenRISC GNU Tool Chain for OR1200 Processor on RHEL 6 server release 6.3 (Santiago).

The steps I have been following for setting up OpenRISC GNU Tool Chain on RHEL 6.3 are:

1. Downloaded the 64 bit tool chain or32-elf-1.0rc1-CentOS-x86_64.tar.bz2 from the link

http://opencores.org/or1k/OpenRISC_GNU_tool_chain#1.0rc1

2. Installed the toolchain from the download archive under the folder /opt/ using commands

a. cd /opt
b. tar xjf or32-elf-1.0rc1-CentOS-x86_64.tar.bz2
c. sudo ln -s or32-elf-1.0rc1 or32-elf
d. sudo ln -s or1ksim-0.5.1rc1 or1ksim

3. Added the PATH into the .cshrc file - setenv PATH /opt/or32-elf/bin:/opt/or1ksim/bin:$PATH

4. As per your suggestion i tried to install the libraries from the link http://opencores.org/or1k/OpenRISC_GNU_tool_chain#Installation_from_source for some reason yum command is not working in my system, so manually downloaded the libraries - binutils-2.20.1, gcc-4.5.1, newlib-1.18.0 and gdb-7.2 from the link http://opencores.org/ocsvn/openrisc/openrisc/trunk/gnu-stable/ and placed it under the folder /opt/openrisc/

5. Before Building the tool chain I tried to install the libraries for the Linux (uClibc) toolchain (or1k-linux) as per the steps mentioned in the link http://opencores.org/or1k/OpenRISC_GNU_tool_chain#Initial_preparations

a. Created a directory mkdir /opt/or1k-toolchain, sudo chown username:username /opt/or1k-toolchain and set the path export PATH=$PATH:/opt/or1k-toolchain/bin

b. Downloaded the OR1K source but the link mention in opencores page is not working so I used this command git clone https://github.com/openrisc/or1k-src.git and used the command

../or1k-src/configure --target=or1k-linux --prefix=/opt/or1k-toolchain \
--disable-shared --disable-itcl --disable-tk --disable-tcl --disable-winsup \
--disable-libgui --disable-rda --disable-sid --disable-sim --disable-gdb \
--with-sysroot --disable-newlib --disable-libgloss

c. Downloaded the Linux Headers and this time to the link mentioned in the opencore page is not work and the right link is git clone http://git.openrisc.net/cgit.cgi/jonas/linux/ (it took long time to download) and used the command make INSTALL_HDR_PATH=${SYSROOT}/usr_headers_install to installed it.

d. Downloaded the ork1-gcc and the right link is git clone https://github.com/openrisc/or1k-gcc.git and used the command

../or1k-gcc/configure --target=or1k-linux --prefix=/opt/or1k-toolchain --disable-libssp \
--srcdir=../or1k-gcc --enable-languages=c --without-headers --enable-threads=single \
--disable-libgomp --disable-libmudflap --disable-shared --disable-libquadmath \
--disable-libatomic

make && make install and installed it.

e. Downloaded the uClibc from the link git clone https://github.com/openrisc/or1k-gcc.git and used the command

make ARCH=or1k defconfig
make && make PREFIX=$SYSROOT install

f. Completed the gcc stage 2 using command

../or1k-gcc/configure --target=or1k-linux --prefix=/opt/or1k-toolchain --disable-libssp \
--srcdir=../or1k-gcc --enable-languages=c,c++ --enable-threads=posix --disable-libgomp \
--disable-libmudflap --with-sysroot=${SYSROOT} --disable-multilib

make && make install and installed it.

./bld-all.sh --force --prefix /opt/openrisc --or1ksim-dir /opt/or1ksim --uclibc-dir uClibc --linux-dir linux --no-newlib --no-or32-elf

The command in the opencores page need to be updated since the last switch --no-or32 to --no-or32-elf

Download Or1ksim from SVN, configure and install in /opt/or1ksim (use --prefix to specify this when configuring).

./bld-all.sh --force --prefix /opt/openrisc --or1ksim-dir /opt/or1ksim --uclibc-dir uClibc --linux-dir linux

I think you have building of three different versions of the tool chain intermingled. For the stable tool chain all you should need is:

Download Or1ksim from SVN, configure and install in /opt/or1ksim (use --prefix to specify this when configuring).

Add /opt/or1ksim/bin to your path.

Download everything from SVN in the gnu-stable directory into somewhere in your home directory.

Download linux and uClibc from git.

Run

./bld-all.sh --force --prefix /opt/openrisc --or1ksim-dir /opt/or1ksim --uclibc-dir uClibc --linux-dir linux

Add /opt/openrisc/bin to you path.

Hi Jeremy,

So here are the steps as I understood from your suggestion.

a. svn co http://opencores.org/ocsvn/openrisc/openrisc/trunk/or1ksim

c. cd builddir_or1ksim

Here the target is specified as or32-elf but I want to install it in a Linux so should I use target as or1k-linux or both since we need to build the tool chain for both (Im sorry I dont know the significance of both)

f. make install

svn co http://opencores.org/ocsvn/openrisc/openrisc/trunk/gnu-stable

a. Do I have to install anything from the gnu-stable diredtory?

git clone http://git.openrisc.net/cgit.cgi/jonas/linux/

a. What is the Path I should use to set the SYSROOT

./bld-all.sh --force --prefix /opt/openrisc --or1ksim-dir /opt/or1ksim --uclibc-dir uClibc --linux-dir linux

I will surly update the link in the Opencores page.

Im very thankful to you for supporting and helping me to understanding the flow to setup the tool chain.

Chetan.
