Ifort LAPACK and Fedora core 2

[Deleted_U_Intel]

Hi,

I have just installed ifort under fedora core 2 but it
doesn't work properly.
I can compile and run simple prgorams.
I can compile and run the tests on BLAS
but when I try to compile LAPACK (downloaded form netlib)
it hangs. Well I should say that it builds the
executables successfully but hangs when it tries to execute them.
It hangs on to start with on ./testslamch.

I tried compiling with and without optimization but with
no success.

Any suggestions ?

Thanks

Paul

The problem is a common one.

The issue is that the low-level machine routines which try to
detect machine floating point parameters are upset by modern optimization. (e.g. SLAMCH.F) I have found that using the -mp1 option seems to help.

on OPTS I have

OPTS=-Vaxlib -O3 -unroll -mp1 -static-libcxa

and
NOOPT = -mp -O0 -fltconsistency -fp_port
