On NERSC Hopper supercomputer, they ask to use a wrapper "ftn" as for a fortran compiler, no matter the compiler we use (intel,gcc,cray).
But when typing
Code: Select all
ftn -V
ftn --version
return a first line that is useless and then the compiler vendor/version.
The problem is that in the configure script (or more precisely m4/lang-fortran.m4) the detection of the compiler is done using
Code: Select all
$1 -V | head -n 1
which will fail for all compiler since the first line is not related to the compiler.
I could bypass this behavior for my cas (Intel) modifying the line with
Code: Select all
sed -n "2p"
which worked.
Abinit now detects "intel 13.1" instead of "generic 0.0".
This issue caused the compilation line not to use the option "-module" which messed up the module compilation and crashed at the very beginning.
Maybe the "head -n 1" should be replaced by a grep line the next line ?
Anyways, I had the problem and solved it myself but I wanted to report it here for any other user in the same situation.
