RE: EPICS 7 Release Candidate 1

[Mark Rivers <rivers@cars.uchicago.edu>]

Folks,

I have successfully built base 7.0.1-rc1, and all of the synApps modules (including asyn, seq and areaDetector) on the following architectures:

linux-x86-64 (Centos 7)
linux-x86 (Centos 7)
windows-x64-static (Visual Studio 2010)
vxWorks-ppc32 (VxWorks 6.9.4.1)

I had to make minor changes to the following modules:

motor
camac
areaDetector
    ADCore
    ADPointGrey
    pvaDriver

These changes have been pushed to the master branch for these repositories on Github.

I applied the following patch to base-7.0.1-rc1 in order for the Windows builds of dxp and quadEM to succeed.  Thanks to Andrew Johnson for this.

There is still a problem building with more recent releases of Visual Studio (2013, 2015, 2017).

Thanks to the core developers for their hard work on this.
