Help with Intel fortran building error with PETSc

Hi,

I am using ifort version 15.0.1 to compile and build my code with the open source PETSc and MPI

Compiling has no error msg but during building, I got the errors below, though in the end the build completed with a working a.out. However, I'm still worried there's some underlying problems. What do these errors mean?

ipo: warning #11021: unresolved xcb_connection_has_error

Internal compiler error with long names - ifort 15.0.2

Hello,

I have recently run into an internal compiler error with ifort 15.0, for a piece of code that works just fine with Ifort 14.0.  I think this is a regression bug.

The catastrophic error shows up when I create a polymorphic pointer to an extended type with a long name, which is defined within a module that also has a long name.  I see the error whenever the sum of the two names (module + type) is equal to or larger than 110 characters.

Please consider the following code:

Questions about Intel® Software Development Suite Student Edition for OS X

Hi,

I have some questions about Intel® Software Development Suite Student Edition for OS X:
http://softwarestore.ispfulfillment.com/store/Product.aspx?skupart=I23S97

1. As shown in "product info", Intel Software Development Suite Student Edition for "Linux" and "Windows" includes the MKL. However, it seems that Intel Software Development Suite Student Edition for "Mac OS X" does not !?!?! Is it true???

historical question

I was recently explaining to a colleague why I chose Intel Fortran for a legacy application that will (assuming we receive the expected funding) undergo a modernization process.  I was missing one historical piece of information.  I know that Intel Fortran is descended from DEC Fortran.  But there is also an HP Fortran, which supports HP's proprietary operating systems, including (Open)VMS.  Was there a point at which a single compiler diverged into the two products we see today?  Is there still sharing of effort/code among the two companies?

Unknown option -xSSE4.2

Hi all,

I am trying to compile a fortran code using ifort (version 10.1) in a linux machine (ia64) as follows

ifort -c -O3 -xSSE4.2 -ip my_code.f90

and I am getting the following warning

ifort: command line warning #10006: ignoring unknown option '-xSSE4.2'.

Could anyone give me a hint to avoid this warning?

(Although I could get the executable by compiling the code without the '-xSSE4.2' option, when I execute it, it stops with segmentation fault !!!)
