MKL in Xcode

Raph — Fri, 29 Aug 2008 21:02:19 GMT

I'm in the process of transitioning from a PPC Mac and xlf to an Intel Mac and ifort. I have managed to transfer over an XCode project, fix the compiler and options and get one program to compile. So I'm pretty sure I have the basics down.

However, another executable in the same project, which unlike the first program links against MKL's LAPACK, does not compile. I can compile and run the same execuatable using Make on the command line, so I'm pretty sure the problem is in configuring the build in XCode.

I'm using Xcode 3.1, MKL 10.0.4.022 and ifort 10.1.017.

Here's what I've done.
1) Added Intel_MKL.framework to the "Link Binary with Libraries".

2) Under build in the Get Info box, I set

LIBRARY_SEARCH_PATHS = /Library/Frameworks/Intel_MKL.framework/Versions/Current/lib/em64t/

USER_HEADER_SEARCH_PATHS = /Library/Frameworks/Intel_MKL.framework/Headers/**

OTHER_LDFLAGS = -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lmkl_sequential -lmkl_core -lguide

I get the following error

ipo: warning #11023: file format not recognized for /Library/Frameworks/Intel_MKL.framework/Versions/Current/lib/em64t/libmkl_intel_lp64.dylib
ipo: warning #11023: file format not recognized for /Library/Frameworks/Intel_MKL.framework/Versions/Current/lib/em64t/libmkl_sequential.dylib

IPO link: can not find -framework Intel_MKL
ifort: error #10014: problem during multi-file optimization compilation (code 1)
Build failed (2 errors, 6 warnings)

Any ideas what I've forgotten to do?

Sounds like you are building a 32-bit XCode target, but linking against the 64-bit MKL.

I finally got back to this problem.

How to I build a 64 bit XCode target? The "Architectures" setting is set to "Native Architecture of Build Machine" on this MacBook. The code compiles, links and runs fine with Make on this machine (see below), so I'm pretty sure 64 bit is the right libraries to use.

Could you add -V to ifort's options to see exactly which version of compiler is used?

Adding -V to the loader in the Makefile adds

Intel Fortran Compiler for applications running on Intel 64, Version 10.1 Build 20080801 Package ID: m_fc_p_10.1.017

and

@(#)PROGRAM:ld PROJECT:ld64-85

Library search paths:

I'm not sure how to do this in XCode.

You canadd -V in Xcode by ->

get info -> build tab -> Intel Fortran Compiler 11.1 -> Additonal options

post the build log.
