Hi Paul,
maybe it's a good idea to enable ifc/icc like this with a shell-compatible
file called intel.sh somewhere in your system:
---intel.sh---
export INTELHOME=/opt/intel/compiler70
export PATH=$INTELHOME/ia32/bin:$PATH
export LD_LIBRARY_PATH=$INTELHOME/ia32/lib:$LD_LIBRARY_PATH
export MANPATH=$INTELHOME/man:$MANPATH
---intel.sh---
Copy this to /etc/profile.d and relogin completely or put a call to it into
your own .bashrc file:
source <path>/intel.sh
Then you can access ifc/icc from any location on your machine and set the
LAM-variables during configuring LAM simply with:
export CC=icc
export CXX=icc
export FC=ifc
and skip the remaining LD_RUN_PATH.
I usually spend some work to find the best set of optimising ifc/icc variables
for the given system. This one is for a Pentium4 machine:
---my config---
./configure --prefix=/opt/intel/compiler70/lam --with-cc=icc
--with-cflags="-O3 -tpp7 -xW -Xa -w -ipo -ipo_obj" --with-cxx=icc
--with-cxxflags="-O3 -tpp7 -xW -Xa -w -ipo -ipo_obj" --with-fc=ifc
--with-fflags="-O3 -tpp7 -xW -w -ipo -ipo_obj" --with-trillium --with-rpi=tcp
--with-rsh=rsh
---my config---
Yes, we are the bad guys and keep on using rsh...
Regards,
Michael
