Subject: Re: [OMPI users] Pb in configure script when using ifort with "-fast" + link of opal_wrapper
From: Rainer Keller (keller_at_[hidden])

Dear Michel,
per the naming convention test in configure:
   ifort -fast
will turn on -xHOST -O3 -ipo -no-prec-div -static,
of which -ipo turns on interprocedural optimizations for multiple files.
Here the compiled object file does not contain the symbols searched for in the
configure-tests.

Looking into the simple test-case in configure and the options that one has to
figure out the naming convention using compilation (-c), I don't see an other
other than disabling -fast & -ipo for intel-fortan compilers.

Please check trunk in commit r21363.

In order to statically link at least the intel-libraries, please add
  -static-intel (in previous intel compilers called -i-static)
to LDFLAGS

With best regards,
