Hi Hinko,
I see the mex compile is using -DEPICS_DLL_NO which is the pre-processor define for static rather than shared libraries, as you mention "shared vs. static build issue" I'm guessing your EPICS base is built as DLLs then? If it is a DLL build then, assuming you can see the variables being exported as Mark describes below, does removing the -DEPICS_DLL_NO from mex make a difference? Alternatively, you could try building your EPICS base as a static library if it is currently a DLL
Regards,
Freddie

You have 3 undefined symbols:
dbr_value_size
dbr_size
dbf_text_dim
Those values should all be defined in ca.dll from EPICS base as shown by the following:

This output is for EPICS base 3.14.12.5, which is the same as you are using.
One possible problem I see is the Makefile you are using is linking ca.lib after Com.lib. This does not seem correct, Com.lib should be linked after ca.lib. You should try swapping those in the Makefile.

Subject: MCA under windows7 64-bit
Hi,
I'm trying to get MCA R4-4 extension built under Windows7, 64-bit, for Matlab 2016a. I'm using Microsoft Windows SDK v7.1 and set of compilers that SDK provides (VS2010?).
EPICS base compilation goes nicely through, using windows-x64 target.
Compiler reports:
c:\MATLAB\R2016a\toolbox\mca>cl

[... lots of cruft that I can post if needed ...]
I'm seeing this problem when linking:

Looking a bit into ca access.cpp source, epicsShareDef is used for dbr_value_size, dbr_size and dbf_text_dim.
Am I hitting shared vs. static build issue?
I'm also not sure if the -DWIN32 is adequate in MCA compile line - I want 64-bit mca mex object.
Any pointers welcomed.
Thanks,
Hinko
