Re: [PerfSuite-bugs] request of information

[Rick K. <rk...@nc...>]

Giuseppe,

I've tried to reproduce your error today using the Intel 9.0 compilers on=
=20
both Itanium and Xeon systems but unfortunately cannot get the same=20
behavior.  That is, I get no link or runtime errors when building the
matvec example.

The message that you are referring to in the INSTALL file is a little bit=
=20
confusing, I think.  It is primarily directed towards problems that were=20
encountered in building the PerfSuite test suite, not example programs or=
=20
actual user applications.  The issue comes down to: how do you link=20
programs properly that mix Fortran and C?  For the matvec example, this=20
should not be an issue as it is completely a Fortran program.

Can you build and run the matvec example that contains no calls to the=20
PerfSuite library?  It should be as simple as doing:

# ifort -o matvec matvec.f

If you can, then we can assume your Fortran compiler is working properly.

The "MAIN_" symbol should actually be contained in your executable, in=20
this case "matvec".  You can see if it is there by running the command
"nm -g matvec | grep -i main".  My output for that command is:

         U __libc_start_main@@GLIBC_2.0
08049b70 T main
08049bbc T MAIN__

I'll wait to hear back from you about these experiments before we try=20
further.  Thanks for your patience and reports.

Rick

p.s. just to reiterate, you can ignore the sentences in the INSTALL file=20
about modifying "config.h".  This was applicable only to the build of=20
PerfSuite itself.  If your test suite runs to completion after you have=20
built PerfSuite (make -s check), your build should be OK.  If not, then I=
=20
would like to see your "config.log" file if you still have it available.
