Hi, all.
I don't know if anyone cares to fix this since it's on EPICS Base
3.14.12.7, but when I generate a new app and IOC with the makeBaseApp.pl
program on Windows and compile it, I get the following warning about a
conversion from "epicsFloat64" to "float" (the full output is at the end
of this email):
===
cl -c -nologo -D__STDC__=0 -D_CRT_SECURE_NO_DEPRECATE -D_CRT_NONSTDC_NO_DEPRECATE -Ox -GL -Oy- -W3 -MD -I. -I..\\O.Common -I. -I.. -I..\\..\\..\\include\\os\\WIN32 -I..\\..\\..\\include -IC:\\opt\\epics-base\\include\\os\\WIN32 -IC:\\opt\\epics-base\\include ..\\xxxRecord.c
xxxRecord.c
..\xxxRecord.c(211) : warning C4244: '=' : conversion from 'epicsFloat64' to 'float', possible loss of data
..\xxxRecord.c(211) : warning C4244: '=' : conversion from 'epicsFloat64' to 'float', possible loss of data

Environment:
* 32-bit Windows 7 Pro
* Visual Studio C++ 2010 Express SP1
* 32-bit Strawberry Perl 5.26.2.1
* EPICS Base 3.14.12.7 + Known Problems patches
* EPICS_HOST_ARCH=win32-x86
Regards,
Lewis
