Open64 is the compiler maintained by AMD, here are the links: and the Community Maintained one

I would love to know how to install it. The instructions from this link: didn't work nor the instructions from the HOWTO-INSTALL-OPEN64 file, which are the same...

It returns error 127 and then error 2.

I want to point out that the community Open64 had no activity for a few years and seems like AMD's Open64 is unmaintained too... – Lilian A. Moraru Feb 21 '14 at 14:30

I got the Open64 compiler built on my 64-bit system running Ubuntu 11.10 by following these steps that I pieced together from a few places:

Make sure you have prerequisites installed:

sudo apt-get install mawk csh bash make flex bison gfortran ia32-libs gcc-multilib g++-multilib gfortran-multilib

Make sure sh is linked to bash and not dash:

sudo dpkg-reconfigure dash

and select 'No'.

Make sure that awk is linked to mawk:

ls -al /etc/alternatives/awk

Fix looking for the crt libraries in the wrong locations by making symbolic links:

cd /usr/lib
sudo ln -s /usr/lib32/crt* .

sudo mkdir /usr/lib64/
cd /usr/lib64/
sudo ln -s /usr/lib/x86_64-linux-gnu/crt* .

Download the Open64 source and uncompress:

cd ~

tar xjvf open64-5.0-0.src.tar.bz2
cd open64-5.0/

Now make another directory inside this for building the compiler

mkdir objs
cd objs

Decide where you want to install, and run the configure script. Replace /opt/open64/5.0 with where you want to install open64. If you want to use the default location, leave off the --prefix argument.

../configure --prefix=/opt/open64/5.0

Now fix an unrecognized option error:

nano ../osprey/ipa/local/Makefile.gbase

and delete or comment out the last line containing:

ipl_summarize_util.o: OPTIMIZER += -CG:all_sched=0

Build the compiler (assuming an 8-core machine, -j 6 seems reasonable)

make -j 6
sudo make install

It worked, Thanks. Would be great if you will also add information how to add the binary to the PATH( it will help the others who will find this post. Bounty in 23 hours. – Lilian A. Moraru Feb 26 '12 at 22:32
Wow! That rocks :] Thanks a lot for this answer. On 12.04 it works as well. – Misery May 28 '12 at 11:36
