I am quite new to EPICS and currently trying to get some synApps_6_1

I want to use EPICS for building a SCADA system for an experimental

Welcome to the community!

re2c.exe -s -b -o lexer.c ../snl.re

The specification of my "building-environment":
* Windows 10, 64-bit, ProcessorArchitecture: AMD64
* x64 Native Tools Command Prompt for VS 2019
* make --version outputs: GNU Make 4.3 Built for Windows32
* perl --version outputs: This is perl 5, version 32, subversion 0
(v5.32.0) built for MSWin32-x64-multi-thread

I followed the instructions in
synApps_6_1/support/documentation/synApps.html. Point 2.4 in this
documentation says: "synApps is tested with the architectures
linux-x86_64, win32-x86, and win64-x86". Does it also run with windows-x64?

There’s a typo in that documentation, there is no win64-x86 architecture, it really means windows-x64. That isn’t your problem though, the sequencer needs another external program “re2c” which those synApps instructions appear to have missed mentioning. If you used Chocolatey to install any of those other tools you can also use it to get re2c, or you can download a pre-built copy from this link.

Since i need asyn, i cannot comment it in support/configure/RELEASE.

You can actually build ASYN and some of the other synApps modules without the sequencer, but it’s probably simpler just to install it.

HTH,

- Andrew
