Intel Compiler support For Mac OS* X 10.7 and Xcode* 4.1

THIS ARTICLE IS OLD AND NO LONGER APPLICABLE. Lion support was added in the version 12.1 compilers.

Product :
Intel Compilers for Mac OS* X

Operating System : Mac OS* X 10.7 aka "Lion"

Support Status: July 19, 2011

Intel Fortran Composer XE 2011 for Mac OS* X and the Intel C++ Composer XE 2011 for Mac OS* X do not officially support use under Mac OS* X 10.7 "Lion". This also applies to official support for integration into Xcode 4.1 - this configuration is not supported at this time.

At this time Intel does not officially support use under Mac OS* X 10.7 and/or integration into Xcode* 4.1.

Compilers versions 11.1 and older are known to NOT work under Lion, and these older compilers will not be updated to work for Lion.

A future update of the 12.x compiler will support Lion, but the currently released 12.0 Update 4 also does NOT support Lion.

Do not upgrade to Lion if you need a working Intel compiler until we officially support Lion.

Official Intel compiler support for Lion will occur sometime after official release of Lion by Apple, whenever that may be.  Typically, Intel attempts to have a compiler update or release to support a major Mac OS* X release within 3 months or less of official launch.  Intel will alert customers to official support in the Release Notes of a compiler update or major release along with notices on our User Forums:

C++ User Forum:  /en-us/forums/intel-c-compiler/
Fortran Linux/Mac User Forum:  /en-us/forums/intel-fortran-compiler-for-linux-and-mac-os-x/

While official support is currently not available, users may find that their existing Intel compilers for Mac OS X may or may not work as expected in this environment.  We do begin early testing during beta phases of Lion and will attempt to make our compilers compatible as soon as possible after official release.  Official support will follow official release of Lion and sufficient time to qualify our compilers under the officially released OS, and must synchronize with our internal release schedules for the compilers.  Again, typically this is 3 months or less after official OS release.

Fortran Note:  The Intel Fortran compiler integration into Xcode is a "Limited Feature", meaning that not all functionality within Xcode is available to Fortran users.  In particular, module dependencies are not detected and not respected: a user must manually compile modules in dependency sequence.  Also, the built-in Xcode debugger is not Fortran language aware, making debug rudimentary and problematic.  These and other current "Limited Feature" Fortran integrations into Xcode are also expected in the integration into Xcode 4.1.  This does not apply to users of Intel C++ for Mac OS X.

After installing OS X 10.9.7 the similar issues with SystemStubs showed up. I searched for three files "libsystemstubs_debug.a, libsystemstubs_profile.a and libsystemstubs.a", but It seems they are not exist any more. Any suggestions would be highly appreciated.

Update? After one year, can we ifort with lion?

Where I can make a download of the ifort10 for my macboopro13 with OS lion?

a few other notes from the community:


It appears Apple moved all the development tools out of /usr/bin and placed them in /Developer/usr/bin

So tips:

install Xcode 4.1
update your PATH to /Developer/usr/bin

not sure but you may need to add /Developer/usr/lib to DYLD_LIBRARY_PATH and maybe LD_LIBRARY_PATH. Would like comments on the need for load library path updates.

I found two problems.
1) Apple moved the g++ compiler. There is a help page about that. You provide the path to the compiler. The link to the page is: If you follow the instructions at the bottom of the page the compiler works to compile.
2) My problem is that the link step fails. ifort is looking for libctr0.10.6.o . Maybe Klaus's trick will help for that, I didn't try it yet.

A comment to Ron. What you say is 100% correct. But people using ifort are developing code and can be expected to be tolerant of complexity and the odd kludgy thing. So when there is a new OS version that messes stuff up it is a big help to have a pointer or two to patch over the problem until the definitive solution can be made available. The goal is to help your customers avoid being dead in the water.

Just my 2 cents.

Klaus, the best way to make a compiler's generated object files and executables compatible with an OS of any kind is to use the linker and libraries of that OS. It's that simple - you want to be compatible, use the system provided linkers, librarian utilities and libraries. Don't fall for easy (but wrong) assumptions or conspiracy theories.

as for official support of Mac OS versions: For official support we have to wait for an OS to have an OFFICIAL release. Yes, we start testing with beta versions, BUT OS vendors often throw in a surprise between last beta version and released version of the OS. So never never never bet that the beta version will match what they release, you will get burned. So after an OS releases, we replace our beta versions and then have to run the next update through a full QA and PV cycle to make sure there are no surprises. Our updates come out on a 3 month cycle roughly, so that is the ceiling function on when you will see support.

Your trick Klaus didn't work for me. It's complaining about not knowing the path to g++

anonymous's picture

this worked for me.
Note that the library names have capitalized S --- libSystemStubs.a etc.

ok,now, after waiting for hours that you post my contribution I will post my remedy on other sources and
mention that INTEL wants to make money by ignoring simple remedies to get the old version running.

By the way: Why does ifort use gcc (I though that GNU is free of charge)???? You earn much money with free software?


anonymous's picture

My remedy (for ifort 12.0, but hopefully also for ifort 11):
copy the 3 libsystemstubs files (libsystemstubs_debug.a, libsystemstubs_profile.a and libsystemstubs.a) from /Developer/SDKs/MacOsX10.6.sdk/usr/lib to /usr/lib.
After that I was able to compile even my large source files with netcdf support!
And Intel CC also works again.
Good luck!
