Re: libimf.so
Thanks a lot.
I am planning for the "install Intel(R) Fortran
Compiler (v 9.1.036)" route, while I am also
downloading the Intel C++ 9.1.042 compiler (to install
only if I get requests, besides ifort, when running
jobs).
If I understand correctly from:
http://www.theochem.uwa.edu.au/fortran/intel_on_debian
the installation of the ifort compiler on debian
requires remastering a rpm package, for which
indications are provided (I never did before such a
procedure). So far I have only untarred the compiler.
Checking the Installation Guide for ifort, do the
"Requirements to develop applications for AMD Opteron"
also apply to my case of simply providing the math
library libimf.so?
If so, I checked my amd64 system, for the requirements
by this 32bit Intel compiler:
#updatedb
$locate libm.so.6 (or libpthread.so.0, or libc.so.6)
showed all three under both
/lib/* (64bit)
and
/emul/ia32-linux/lib/* (32bit)
In contrast, both libstdc++.so.5 and lib_s.so.1 are
only present at 64bit, the former in /usr/lib/
(together with version so.5.07), and the second in
/lib/. Should the 32bit versions be provided? I never
managed 32bit libraries in my system. What is there is
from the base installation, subsequently added of X
("nv" driver, no nvidia drivers) and gnome (both
started only if needed, the system boots on $).
I wondered whether recompiling (I have the source)
with GNU compilers would be a better route, though it
is an extremy complex application, difficult to carry
out from scratch for a single case.
One further question: the package compiled with ifort
for amd64 (as indicated in my previous email
reproduced below) was installed as user in my HOME.
Should I install the Intel compiler as root or as
user?
Thanks for this further guidance and for your patience
with people like me who have only scattered knowledge
of these affairs.
cheers
