How to get rid of so many warning message when compiling fortran code in Mac Sonoma?

[tz0616]

 Hi,

 I get so many warning messages (see below) when I compile a fortran code in Mac Sonoma.

 I am using intel fortran compiler 2023.2.0 build.

 Could you direct me how to get rid of so many warning messages?

 Thanks a lot

[andrew_4619]

there are numerous -warn: options  to control diagnostic output, see https://www.intel.com/content/www/us/en/docs/fortran-compiler/developer-guide-reference/2023-0/warn.html

[tz0616]

How to suppress this specific warming "ld: warning: -keep_dwarf_unwind is obsolete" ?

Thanks

[Steve_Lionel]

These are not compiler warnings, they are ld warnings. An earlier report is 'no platform load command found in' ... macOS - Intel Community  for the "no platform" messages. The first couple of messages are different, and possibly due to incompatible changes introduced by Apple. One of Intel's Mac experts will need to comment.

[Barbara_P_Intel · Accepted solution]

macOS Sonoma is not supported. See the System Requirements.

[mcdssmwa]

I get exactly the same problem on my Mac M2 with Ventura 13.6

[DSfusion-1972]

I'm also getting similar warning messages under MacOS Ventura. According to what I saw on your System Requirements link, you are supposed to still be supporting MacOS Ventura.

[Ron_Green]

Do you have a reproducer and build script or makefile?

Or perhaps a list of your compile and link options?

[DSfusion-1972]

Hi Ron,

Yes, I have attached a tar file that contains the source code and a build script (build_far3d.sh). Let me know if you have questions.

Don

[Barbara_P_Intel]

Intel Fortran is only supported for Mac* computers with Intel® Processors.

[DSfusion-1972]

I'm running on a MacBook Pro with a 2.7 GHz Quad-Core Intel Core i7 processor, so I would think that should still be supported.

Don

[Barbara_P_Intel]

@DSfusion-1972, you're fine with an Intel processor; we'll work on that. It's @mcdssmwa who's using Apple silicon.

[Ron_Green]

You can try this option:

 -Wl,-ld_classic

this gets rid of the bulk of them but leaves a couple:

$ ifort hello.f90 -Wl,-ld_classic

-macosx_version_min has been renamed to -macos_version_min

ld: warning: -keep_dwarf_unwind is obsolete
$
$ ./a.out

but as has been said, ifort is no longer officially supported on macOS.
