Thread Subject: MEX 'specified procedure could not be found' in 2007b

Hello,

I am a user of the "ndfun" function, created by Peter
Boettcher to enable matrix operations on n-dimensional arrays.

After switching to 2007b, I re-compiled it from the C code
(with the BLAS and LAPACK libraries in the command line, as
the help page suggested) with no problem.

Now, when I try to use it, I get the following error:

??? Invalid MEX-file 'D:\.....\ndfun.mexw32': The
specified procedure could not be found.

This is not an issue of version incompatibility, as I have
just compiled it on this very system (hence a different
issue from the one reported here:
www.mathworks.com/matlabcentral/newsreader/view_thread/153618 )

Any ideas?

-Tom

Hi Tom,

I suggest you try DependencyWalker, it's a free tool you can
use to find out if there's some libraries missing. It can be
downloaded from
http://dependencywalker.com/
Just open your *.mexw32 with the tool and check what's missing.

Regards,
Martti

A CHOLMOD user just emailed me with the same problem - not
with ndfun but with CHOLMOD. Curious ... seems that it
might not be related to NDFUN or CHOLMOD but to a compiler
issue.

With 2007b lcc compiler, to me it seems to be impossible to
get both LAPACK and BLAS linked to the mex dll. In my
system, only the library mentioned first when calling mex
gets linked. That behaviour is only when using lcc.

Has any solution been found for this issue? I'm running into
the same thing trying to get pseudomarker
(http://research.jax.org/faculty/churchill/software/pseudomarker/index.html)
to work on 2007b.

Thanks
