For what it is worth, lbfgs works on linux.
I stuck it on github, along with fortran source and Makefile in case it helps
others.

I also took the liberty of using the same code to do the box constrained
version of the algorithm. The example is no good, and I t
I guess you need not known the meaning of LASTIN because it is just
an arbitary global noun for holding the last input arguments.
Lapack does not work in linux64 becuase the lapack.so in that addons
is 32-bit only.

I'm pretty familiar with lbfgs and lbfgsb and wouldn't mind having a crack at
this. It looks straightforward to do, but I am stumped as to what LASTIN
means. The only other place where this word is mentioned is in Lapack, and
those don't work on my 64 bit Linux machine.

So you have moved
Yes, I did move from J6 on Windows to J7 on Mac
I browsed the links you sent. Linking J7 to lbfgs on a Mac looks a
formidable task or at least a task requiring much expertise that I
don't have. Maybe someone with such expertise can
do this. I, for one, would be very grateful.

Looking at the manifest for math/lbfgs it has only been released for
Windows and J6.

To get it working on Mac (or Linux) the .dylib or .so versions of the
.dll will be required.

No, *.dll files cannot be made to run on the Mac. That is -- not when
it's running MacOS. (But yes -- it's actually possible to get the Mac
running Windows using a product called BootCamp).
The counterpart on the Mac to the dll is called a dylib. People who
ship compatible Mac and Windows versions
Thanks for your help. I got deoptim to work with my minimization problem.
I run J7 on a Mac.
Are *.dll files supported on a Mac?
Know almost nothing about getting a ddl to work with J.
Thanks again for your help.

Yes I understand my typo:+/@*: should have been +/@:*:

By the way, if you use getDEoptim instead of deoptim the output is as
a table with labels in the first column and maybe easier to interpret
i.e.
getDEoptim 'ssq_base_'; _3 3

looking through the test script which I've fixed the link to on the
wiki page for the addon. It has some simple examples there.

As you said, there seem to be a number of issues:
