Before installing the compiler, you should make sure that the following 3 environment variables are set properly, so that ORC v.2.1 is used by default:

Variable Name	Purpose
TOOLROOT	Specify the root for ORC binaries hierarchy, e.g., $HOME/orc-2.1
COMP_TARGET_ROOT	For cross compiler: Specify the root for native archive hierarchy, so that cross ORC binaries will pick up native archives from $COMP_TARGET_ROOT/usr/ia64-orc-linux/lib, For native compiler: Native ORC binaries will pick up archives from $COMP_TARGET_ROOT/usr/lib. Normally, you need *NOT* set this variables for native ORC, so that ORC will use the archives in /usr/lib.
PATH	For native compiler: Add $TOOLROOT/usr/bin to $PATH. For cross compiler:  You should add $TOOLROOT/usr/ia64-orc-linux/bin to $PATH, and make sure your $PATH satisfy the following 2 conditions (outside NUE) 1. Each time when you invoke orcc, $TOOLROOT/usr/ia64-orc-linux/bin/orcc is picked up 2. Each time you invoke as (or ld) from console, your original as (or ld) rather than $TOOLROOT/usr/ia64-orc-linux/bin/as(or ld) is used

How to install the pre-built cross compiler on IA32 machine

　

To install the cross ORC compiler (This binary release is prepared for RedHat 7.2 or higher version):

• Download NUE and install it, you may need to reset the two symbolic links as described above

• Set environment variables properly as described above
• Download orc-2.1-bin.tar.gz from http://prdownloads.sourceforge.net/ipf-orc/orc-2.1-bin.tar.gz
  
• Expand it by "tar zxvf orc-2.1-bin.tar.gz"
  

• Do "cd orc-2.1-bin; ./install.sh -c"
  

Here is an installation example:

　

Assume the account name is joesmith and the IA-32 RedHat 7.2 host name is rose, the login shell of joesmith is GNU BASH. Pay attention to the HIGHLIGHTED part that should not be set for native compiler [joesmith@rose joesmith]$vi $HOME/.bashrc # set $TOOLROOT $COMP_TARGET_ROOT and $PATH [joesmith@rose joesmith]$cat $HOME/.bashrc | grep "TOOLROOT\|PATH" export TOOLROOT=$HOME/music export COMP_TARGET_ROOT=$HOME/photo export PATH=$PATH:$TOOLROOT/usr/ia64-orc-linux/bin [joesmith@rose joesmith]$source $HOME/.bashrc [joesmith@rose joesmith]$tar zxvf orc-2.1-bin.tar.gz [joesmith@rose joesmith]$cd orc-2.1-bin; ./install.sh -c

Note that the nue command will put you under your home directory inside NUE, which may not be your regular home directory. If you want to do cross compile inside NUE, you need to make sure that the ORC binaries are under a directory that is accessible under NUE.

　

ORC 2.1 release allows the users to produce IA64 binary on IA32 machines directly. Simply follow the install instructions to set the environment variables and install the pre-built native archives properly.

How to install the pre-built native compiler on IA64 machine

On an IA64 machine (This binary release is prepared for RedHat 7.2):

• Set the environment variables properly as described above, NOTE: You need not set COMP_TARGET_ROOT

• Download orc-2.1-bin.tar.gz from http://prdownloads.sourceforge.net/ipf-orc/orc-2.1-bin.tar.gz
  
• Expand it by "tar zxvf orc-2.1-bin.tar.gz"
• do "cd orc-2.1-bin; ./install.sh -n"

Here is an installation example:

　

Assume the account name is joesmith and the IA-64 Redhat 7.2 host name is uranus, the login shell of joesmith is GNU BASH. [joesmith@uranus joesmith]$vi $HOME/.bashrc # set $TOOLROOT and $PATH [joesmith@uranus joesmith]$cat $HOME/.bashrc | grep "TOOLROOT\|PATH" export TOOLROOT=$HOME/music export PATH=$PATH:$TOOLROOT/usr/bin [joesmith@uranus joesmith]$source $HOME/.bashrc [joesmith@uranus joesmith]$tar zxvf orc-2.1-bin.tar.gz [joesmith@uranus joesmith]$cd orc-2.1-bin; ./install.sh -n

You can verify your installation by doing a simple "hello world"

　

$cat hello.c

#include <stdio.h>

main()

{

printf("hello world\n");

}
