Experimental Physics and
Industrial Control System

I am trying to build the master branch of https://github.com/epics-extensions/ezcaIDL on windows-x64 with base 7.0.4 and VS 2015.  This used to build OK, either on an earlier version of base or VS or both.

 

This extension builds a shareable library/DLL to call Channel Access from IDL.  It depends on extensions/ezca and extensions/EzcaScan.  Both of those libraries build fine on Windows.

 

ezcaIDL builds fine on Linux.  However, on Windows I get this:

 

H:\epics\extensions\src\ezcaIDL>make

make -C O.windows-x64 -f ../Makefile TOP=../../.. \

    T_A=windows-x64 install

Note that it uses a .DEF file to define what symbols should be exported.

 

Has support for that changed?  If so, how do I need to do it now?

 

Thanks,
