MATLAB Central Newsreader - after mex-file Matlab exists with "Alarm clock"

after mex-file Matlab exists with "Alarm clock"

Ben Abbott — Sat, 23 Jun 2007 13:14:56 -0400

I've been using g95 to produce mex-files for Matlab (r2006b) on a PPC
Mac running OS X 10.4.10.

A short period after running the mex-file, Matlab exists. Running
Matlab from a terminal window (command line), an error/comment is
issued as Matlab exists. The error is simply "Alarm clock".

Any thoughts?

I did a timing and found that the "alarm" occurs 10 minutes after the
mex-file is run.

When the mex-file is run several times the timing increases. However,
I'm not yet sure of the progression.

Of course, the progression is not directly relevant. What I need is a
way to turn if off!

Any thoughts?

Ben, please see this thread on the g95 mailing list:

I believe the developers of g95 have produced a fix for this issue in
v0.91. You may want to contact them to check that this is the case
before upgrading.

I have confirmed with Andy the developer of g95. He says that the fix is in
0.91. I've run rudimentary testing and this issue goes away if you use
version 0.91.

Note that g95 0.91 has not been qualified with MATLAB. Use it at your own
risk.

Thanks Eric

I checked my g95 version ...

Using built-in specs.
Target:
Configured with: ../configure
--prefix=/sw/lib/gcc-lib/powerpc-apple-darwin8/4.0.3
--enable-languages=c --with-as=/sw/lib/odcctools590/bin/as
--with-ld=/sw/lib/odcctools590/bin/ld
--with-nm=/sw/lib/odcctools590/bin/nm --with-included-gettext
Thread model: posix
gcc version 4.0.3 (g95 0.90!) May 5 2007

Unfortunately, Fink doesn't have a more recent g95 available. I'll
contact Fink's maintainer for g95 to see if he can do an update.

In the meantime, can you put in a work ar Mathworks to have other
Fortran compilers supported on the Mac (other than Absoft, pls). I'd
love to be able to mex with both g95 and gfortran ... Intel Fortran
would be great as well!

Thanks again!
Ben
