Mark,

I now have EPICS base-3.14.6 and asyn-4.0 building under Cygwin thanks.

However, my application won't build and complains of undefined references to
various devGpib functions (even though I have added the device driver and
asyn libs in the relevant Makefiles).

Eg.

... undefined reference to `_devGpib_initAi'
<snip>
... undefined reference to `_devGpib_readSi'

Any tips please?

Mark

Subject: RE: Asyn build under win32

Hi Mark,

asyn does not build under the win32-x86 architecture, for the reasons
you discovered.  It uses the termios API for serial ports, and that does
not seem to be available under native Windows.

I am running quite a few IOCs on Windows machines now, for controlling
Roper CCD detectors, XIA spectroscopy detectors, and running small
laboratories with RS-232 motor controllers.  I use the cygwin-x86
environment so that I can use asyn.

To develop applications with cygwin you need to install basic cygwin
plus "make", "gcc", "perl", "g++" and the "SUN rpc" package.  However,
to run an application that has been built statically with cygwin-x86 you
only need to install the basic cygwin package on the target machine, and
that takes about 2 minutes.  Really all it should need is to have
cygwin1.dll in your PATH on Windows.

With the exception of the message I posted to tech-talk yesterday about
some CA problems, I have had excellent experience with cygwin.  I think
the problems I had yesterday should be viewed as an anomaly, perhaps due
to an errant application.  Rebooting has fixed the problem, at least for
now.
