MATLAB R2012a LAPLACK BLAS load error Mac OSX Lion

I just installed MATLAB R2012a on a relatively new MacBook with OSX Lion. Install and activation was clean. The first thing I tried to run was "bench" in order to verify the install. I was surprised when bench crashed with the following error:

libmwlapack: load error: dlopen(mkl.dylib, 1): no suitable image found.  Did find:
  /Applications/MATLAB_R2012a.app/bin/maci64/mkl.dylib: truncated mach-o error: segment __LINKEDIT extends to 21094872 which is past end of file 21094672

Caught "std::exception" Exception message is:

I have tried reinstalling twice, once with a minimal install (custom install option, selected only MATLAB and Simulink) and once with all of my toolboxes (typical install option). So far, no luck getting past this error.

Some of my m-files will execute, but any dependent on BLAS or LAPACK fail with a similar error as above. I have no MEX-code (although I'm not sure what bench uses).

Hope someone out there has an idea on what is happening here!

This is strange indeed. Can you open a Terminal application and run the following command:

ls -l /Applications/MATLAB_R2012a.app/bin/maci64/mkl.dylib

and compare against my working R2012a MATLAB, also installed on Lion:

-r-xr-xr-x 1 local admin 21094872 Dec 29 01:22 /Applications/MATLAB_R2012a.app/bin/maci64/mkl.dylib

It is exactly the same?

It appears that the file size is different than yours. File size is coming in at 21094672. Missing 200 bytes somewhere...

[Ken Atwell]

Sounds like those 200 bytes are important! Did you download off the web site, or install from a DVD? If the former, I would try re-downloading the MATLAB image from scratch (you mentioned re-installing above, but not re-downloading) before re-installing. If the problem *still* persists, MathWorks support should be able to get your a clean copy of this file to drop in by hand.

[M-flyer]

I tried reinstalling from a DVD (using the same .ISO) which failed similarly. I then installed using downloads from the MATLAB web site (internet method) and it appears to be working correctly. I must have an issue with the ISO image...I did not calculate an MD5 checksum on it...perhaps I should have. Regardless I appear to have a functional install. Thanks for the suggestions.

Reinstalling from a web-based download versus the ISO solved the problem.
