I like to use “make -sj” so it is fast and only shows me warnings and errors.  But it is then possible to miss the fact that the build actually failed because the failure message has scrolled away to be followed by warnings from a thread that is still building.

So I then typically run “make -sj” again to make sure there is no output, confirming that the previous build succeeded.

This change makes that no longer possible. I wonder if minute precision is really useful?

What you are describing is a result of a change I made
to include VCS revision in the build in place of __DATE__.

This makes the output of eg. iocInit a bit more useful.

Starting iocInit
############################################################################
## EPICS R7.0.4.1-DEV
## Rev. R7.0.4-36-g4ba9dafeef3934e5e10d

Or anything which calls coreRelease() from epicsRelease.h

If no VCS tool is in use (eg. no '.git'), or not available,
the default fallback is to use the current time with minute precision.

Actually on base 7.0.4 it does recompile on Linux as well, you just don’t see any output if using –sj.



But this problem does not occur on base 7.0.3.1.  Here is the output when I rebuild with windows-x64-static on base 7.0.3.1.



H:\epics\base-7.0.3.1>make -sj8



H:\epics\base-7.0.3.1>



It does not do anything, but on 7.0.4 there is lots of output as it recompiles and rebuilds libraries each time you run it.

When I try to build base 7.0.4 on windows-x64-static with Visual Studio 2015 I have the following issues, which appear to be minor:



1)      “make clean uninstall” produces many error messages like this:



H:\epics-devel\base-7.0.4>make -sj clean uninstall

Can't locate EPICS/Path.pm in @INC (you may need to install the EPICS::Path module) (@INC contains: H:/epics-devel/base-7.0.4/src/tools/../../lib/perl C:/Perl64/site/lib C:/Perl64/lib .) at H:/epics-devel/base-7.0.4/src/tools/convertRelease.pl line 24.

…



2)      “make –sj” produces these messages:



H:\epics-devel\base-7.0.4>make –sj8 > windows_build1.txt

3)      Normally when “make” completes successfully and then one runs “make” again it does not actually do anything.  For base 7.0.4 that is what I observe for Linux.  But on Windows every time I run “make” after it has completed successfully it produces the following output.
