Experimental Physics and Industrial Control System
Hi Michael,
Visual Studio C runtime used 3 digit exponents by default prior to VS 2015, but you can change this behaviour.
https://msdn.microsoft.com/en-us/library/0fatw238(v=vs.120).aspx
in VS 2015 the above function is withdrawn and 2 digit exponents are used, so you'd need to protect any usage of this function with something like
#if defined(_WIN32) && defined(_MSC_VER) && (_MSC_VER < 1900)
Regards,
Freddie

the dllimport/export issue is fixed. My mistake in including epicsExport.h in the wrong place.
The test failure is at least diagnosed:
> not ok 739 - cvtFloatToString(1e+08, 6) == 12 (13) -> "1.000000e+008"
> ok 739 - cvtFloatToString(1e+08, 6) == 12 (12) -> "1.000000e+08"
An extra zero in the exponent. I don't see this as a blocker for a pre-release.
I also fixed an issue with the filterTestHarness and filter registration. The RTEMS tests, individual and test harnesses, now pass for me with qemu.
