Re: MCSim on Cygwin

I have not tried to compile MCSim under Cygwin, but have successfully
compiled and used it under MinGW, using the tools for compiling R and R
packages called Rtools.  I submitted a patch to Frederic which he has
made available at the MCSim web page. Only statically-linked executables
are produced, but I question the advantage of using dlls for the mcsim
library, as it is small, and I understand there is a small performance
hit of using a dll over a statically-linked library (but my
understanding in these matters is small, and I'm quite open to being
wrong on this).

RE: MCSim on Cygwin

I'm less concerned about using DLL's versus statically linking libraries and
executables than I am about trying to come up with a stable way to build and
use MCSim on a windows (or even a Mac OS) platform. In both cases I have
found only anecdotal accounts of how people have been able to manually
install and use it rather than specific and clear instructions.

I think too, the benefit to making an open source product available is to
allow the community to enhance the source and the documentation regarding a
wide variety of platforms. Open source that compiles only on a limited
platform is not much more useful than a proprietary tool.

I'm coming at MCSim not so much as a biological modeling end user, but
rather as a computer scientist who has been asked to evaluate, recommend and
provide local support for such tools as would enhance the capabilities of
our team of modelers. I'm more than willing to help improve the portability
of MCSim if it would help make it more useful to us in the process.

Thanks; I'll check it out.

FWIW, I have no real problem with statically linked MCSim models.

Tim,

I just saw your note tonight, and I must say I'm not a biological
modeling end user, either.  I come at this from the field of system
dynamics, which normally uses commercial simulators such as Vensim and
iThink or STELLA.  http://facilitatedsystems.com/links.html#sd points to
a talk and a quick reference guide I created on MCSim, if it helps
anyone.

I agree that it's important to the larger picture to have MCSim work
across platforms.  When I first found it, I was running cygwin on XP,
and I seem to recall it compiling quite easily.  Unfortunately, that
wasn't the case when I tried it again recently, but I haven't had time
to get back to it in a few weeks.  I'll continue to try to make it work,
for I need (or want) to use it in my work where I am in a Windows
environment.

Bill

New patch for Windows installation

A new patch has just been posted for installing version 5.3.1 under Windows
(see http://www.gnu.org/software/mcsim/WindowsInstall.html).
