Experimental Physics and
Industrial Control System

I have made some progress.  I changed the Makefile as follows:

 

******************************

diff --git a/Makefile b/Makefile

index cc33f71..4f85930 100644

--- a/Makefile

+++ b/Makefile

@@ -18,11 +18,13 @@ SCRIPTS_HOST = ezcaIDL.pro ezcaIDLWidgets.pro

 

SHARED_LIBRARIES=YES

LOADABLE_LIBRARY_HOST_Darwin = ezcaIDL

+STATIC_BUILD=YES

LIBRARY_HOST_DEFAULT = ezcaIDL

LIBRARY_HOST_Darwin = -nil-

ezcaIDL_LDFLAGS_WIN32 += /manifest

ezcaIDL_SRCS = ezcaIDL.c

ezcaIDL_LIBS += ezca EzcaScan ca Com

-ezcaIDL_SYS_LIBS_WIN32 = ws2_32 advapi32 user32

+ezcaIDL_SYS_LIBS_WIN32 = ws2_32 advapi32 user32 msvcrt

+USR_LDFLAGS_WIN32 += /nodefaultlib:libcmt

******************************

 

STATIC_BUILD=YES was required to get the linker to use the statically built libraries for ezca and EzcaScan.

 

I needed to add msvcrt to SYS_LIBS_WIN32, otherwise it gave an error that functions from the C run-time were undefined.

 

I needed to add the nodefaultlib to prevent a warning the libcmt was not compatible.

 

Perhaps there is a better solution to the above 2 problems.

 

Once I made those changes then I still get warnings like this:

ezcaIDL.obj : warning LNK4197: export 'EzcaMonitorQueue_Zero' specified multiple times; using first specification

 

but it builds OK.  It is exporting the undecorated symbols, as I want.  The DLL does not depend on ezca.dll or EzcaScan.dll, as I want.  However, it does depend on Com.dll and ca.dll, which I do not want.

 

I then tried a different approach.  I used the windows-x64-static architecture, rather than windows-x64.  I was able to revert to the original Makefile.  Although it is the static architecture, the Makefile defines SHARED_LIBRARIES=YES so it will build the DLL. I still get the warnings about exports defined multiple times.  I then get this error:

Is there a way around that error?

 

Thanks,

Note that the existing version of the DLL am using was built in 2013, so it is definitely built with old versions of base and Visual Studio.

 

This is the output of dumpbin/exports, which shows that the DLL is exporting undecorated symbols, which is what I need.

This is the output of dumpbin /imports, which shows that although the DLL uses the Com and ca libraries, they are statically linked into the DLL, there is no dependency of the DLL on Com.dll or ca.dll.  That is what I want, so I can easily distribute the DLL without any dependencies.

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:
