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
Microsoft (R) C/C++ Optimizing Compiler Version 16.00.30319.01 for x64
Copyright (C) Microsoft Corporation.  All rights reserved.

MCA compile line taken from one of the alt_compile files in mca.

c:\MATLAB\R2016a\toolbox\mca>mex mca.cpp MCAError.cpp Channel.cpp

c:\base-3.14.12.5\lib\windows-x64\Com.lib

c:\base-3.14.12.5\lib\windows-x64\ca.lib -DDB_TEXT_

LBLSOURCE -DMSCC -DEPICS_DLL_NO -DWIN64 -Ic:\base-3.14.12.5\include

-Ic:\base-3.14.12.5\include\os\WIN32 -v -DWIN32

[... 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
