Hi,

I’ve compiled and run base 3.14.12.5-rc1 on Windows 8 64bit with Visual Studio 2013, shared build, both windows-x64-debug and windows-x64 as EPICS_HOST_ARCH targets - all built OK and “make runtests” passed too :-)

I noticed a couple of warnings in the build log that might have some relevance

c:\epics-base-3.14.12.5-rc1\src\ca\oldAccess.h(594) : warning C4930: 'epicsGuardRelease<T> guardRelease(void)': prototyped function not called (was a variable definition intended?)
        with
        [
            T=epicsMutex
        ]
        c:\epics-base-3.14.12.5-rc1\src\ca\sgAutoPtr.h(59) : see reference to function template instantiation 'void ca_client_context::whenThereIsAnExceptionDestroySyncGroupIO<T>(epicsGuard<epicsMutex> &,T &)' being compiled
        with
        [
            T=syncGroupWriteNotify
        ]
        c:\epics-base-3.14.12.5-rc1\src\ca\sgAutoPtr.h(55) : while compiling class template member function 'sgAutoPtr<syncGroupWriteNotify>::~sgAutoPtr(void)'
        ..\CASG.cpp(216) : see reference to function template instantiation 'sgAutoPtr<syncGroupWriteNotify>::~sgAutoPtr(void)' being compiled
        ..\CASG.cpp(216) : see reference to class template instantiation 'sgAutoPtr<syncGroupWriteNotify>' being compiled

Passing “guard” as the argument would remove the warning, but I don’t know if that is the desired behaviour. Removing the () from the line gives a “no appropriate default constructor” error.   

cl -c              /favor:blend   /nologo /D__STDC__=0 /D_CRT_SECURE_NO_DEPRECATE /D_CRT_NONSTDC_NO_DEPRECATE   /Zi /RTCsu   /W3 /w44355        /MDd     -I. -I..\\O.Common -I. -I.. -I..\\..\\..\\include\\os\\WIN32 -I..\\..\\..\\include         ..\\tool_lib.c 
tool_lib.c
c:\epics-base-3.14.12.5-rc1\include\alarmString.h(30) : warning C4273: 'epicsAlarmSeverityStrings' : inconsistent dll linkage
        C:\epics-base-3.14.12.5-rc1\include\alarm.h(46) : see previous definition of 'epicsAlarmSeverityStrings'
c:\epics-base-3.14.12.5-rc1\include\alarmString.h(40) : warning C4273: 'epicsAlarmConditionStrings' : inconsistent dll linkage
        C:\epics-base-3.14.12.5-rc1\include\alarm.h(101) : see previous definition of 'epicsAlarmConditionStrings'

epicsAlarmSeverityStrings is declared epicsShareExtern in alarm.h but just extern in alarmString.h – making both extern removes the warning, making them both epicsShareExtern causes a “error C2491: 'epicsAlarmSeverityStrings' : definition of dllimport data not allowed” issue when compiling  tool_lib.c 

I also enclose a diff of a couple of minor mods I have locally in 3-14-12-4:
* With a debug build on windows, isprint() throws an exception if the function argument is < 0
* The windows implementation of currentTime::getCurrentTime is missing a divide by EPICS_TIME_TICKS_PER_SEC when reporting a time discontinuity

Regards,

Freddie
