Thanks, static would be good if it's possible. I'm not sure how that would work with sharing the channel access state between functions.

Correct. Since matlab requires each entry point to be a separate 'mex'
file it is not possible
to link everything together into a single static executable.
Hence, you *must* use (and distribute) dlls.

Sounds good.
James, I will zip up the dlls and send to you. :)

Cheers,
Ernest

Hi Ernest

Please can I have the binaries while I work out what's wrong with the Visual Studio 2010 build, I don't have 2008.

Sure.
I will zip it up and mail it to you.
Or maybe, I should create a static executable?

I meant library

Cheers,
Ernest

I built it on 64-bit windows7 for matlab 2011a. I don't recall what
compiler version

Hi,
I used MS Visual Studio 2010

I can provide binaries as well. :)

Cheers,
Ernest.

was used. Maybe Ernest can fill us in. He should also have access to
the binaries; if you're lucky they work for you.

Hi

Has anyone got labCa 3.4 to build on windows-64? If so, what
combination of Matlab, Windows and Compiler are you using. I can't
get it to work with Windows Server 2008, MatlabR2011b, Visual Studio
2010, EPICS 3.14.12.1

Initially the build fails building ezcaglue with some missing libraries:

Adding ws2_32 and advapi32 to USR_SYS_LIBS fixes this but the mex functions

fail:
