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 ~
wget http://downloads.sourceforge.net/project/open64/open64/Open64-5.0/open64-5.0-0.src.tar.bz2
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
