Hello everyone,
I'm new in mac and with IMKL too, trying to get up some f90 codes for signal processing in a

Macmini3,1. 1Proc, two cores (In the near future we expected to run our applications in a cluster of similar Macs).

After a while I was able to compile without errors, nevertheless the executable doesn't run. Showing the error in the thread title. Here down details:

MKLPATH=/Developer/opt/intel/Compiler/11.1/088/Frameworks/mkl/lib/em64tMKLINCLUDE=/Developer/opt/intel/Compiler/11.1/088/Frameworks/mkl/include/em64t/ilp64Script:ifort -o exec $1 $2 -L MKLPATH -I MKLINCLUDE/Developer/opt/intel/Compiler/11.1/088/Frameworks/mkl/lib/em64t/libmkl_intel_ilp64.dylib /Developer/opt/intel/Compiler/11.1/088/Frameworks/mkl/lib/em64t/libmkl_intel_thread.dylib /Developer/opt/intel/Compiler/11.1/088/Frameworks/mkl/lib/em64t/libmkl_core.dylib /Developer/opt/intel/Compiler/11.1/088/lib/libiomp5.dylib -openmp -lpthreadwhen you execute your recently compiled file, the following output is shown:dhcp-0083712665-16-41:FFT_INTEL_MAC erwin$ ./execdyld: Library not loaded: libmkl_intel_ilp64.dylibReferenced from: /Users/erwin/Desktop/FFT_INTEL_MAC/./execReason: image not foundTrace/BPT trapdhcp-0083712665-16-41:FFT_INTEL_MAC erwin$ ./execdyld: Library not loaded: libmkl_intel_ilp64.dylibReferenced from: /Users/erwin/Desktop/FFT_INTEL_MAC/./execReason: image not foundTrace/BPT trap___I'll thank any help or comment you can share with me.In advance thanks a lot.C.

Hi,

Have you setDYLD_LIBRARY_PATH to point to the directory location of the Intel MKL dylib's?

Example:

export DYLD_LIBRARY_PATH=/Developer/opt/intel/Compiler/11.1/088/Frameworks/mkl/lib/em64t/

Hello Todd,

Thank you for your answer, I already included this path and the compilation is going well, but now when Im trying to run de application the following output is obtained:

dhcp-0083712665-16-41:FFT_INTEL_MAC$ ./exec

dyld: Library not loaded: libiomp5.dylib

Referenced from: /Users/rwm/Desktop/FFT_INTEL_MAC/./exec

Reason: image not found

Trace/BPT trap

I looked for this particular library to address the compilation to take into account it, and there are

sh-3.2# find / -name libiomp5.dylib -print

/Applications/MATLAB_R2009b.app/bin/maci/libiomp5.dylib

/Applications/MATLAB_R2009b.app/bin/maci64/libiomp5.dylib

find: /dev/fd/3: Not a directory

find: /dev/fd/4: Not a directory

/Developer/opt/intel/Compiler/11.1/088/lib/libiomp5.dylib

/Library/Frameworks/Intel_MKL.framework/Versions/10.0.5.025/lib/32/libiomp5.dylib

/Library/Frameworks/Intel_MKL.framework/Versions/10.0.5.025/lib/em64t/libiomp5.dylib

/Library/Frameworks/Intel_MKL.framework/Versions/10.0.5.025/lib/universal/libiomp5.dylib

/opt/intel/Compiler/11.1/088/lib/libiomp5.dylib

I tried to compile pointing out to all of these paths, nothing worked. So I copied the libiomp5.dylib file to the folder

/Library/Frameworks/Intel_MKL.framework/Versions/10.0.5.025/lib/em64t/

and now I was able to compile with out errors. Nevertheless there are some run time errors:

dhcp-0083712665-16-41:FFT_INTEL_MAC $ ./exec

forrtl: severe (174): SIGSEGV, segmentation fault occurred

One of the probs could be that the libiomp5.dylib is not loaded into the OS. Doing this with ld.so.conf + ldconfig in linux is extremely easy, but I dont know how to do this in Mac OS X.

Any advise will be very welcome!

Thank you for your attention.

Best

Evns

Thanks for the help, it

Hi,

In OSX* there are fat MKL libraries, so please set DYLD_LIBRARY_PATH to MKL lib location without arch-specific word just .../mkl/lib

Hi all sorry to bother you

Hi all sorry to bother you but I'm having similar problems.

I get this error when running first v 12

dyld: Library not loaded: libiomp5.dylib

So I tried fixing it by entering this into the console

DYLD_LIBRARY_PATH="/opt/intel/composer_xe_2013_sp1.1.103/compiler/lib"

but no luck.

any hints would be much appreciated
