Subject: re2c on Windows

Folks,

I am trying to help someone build EPICS on Windows.  They need to have a copy of re2c.  I see that on my Windows machine I have re2c.exe which I put in C:\Program Files\re2c.  When I run that I see the version is 1.0.3.

C:\Windows\System32>re2c --version
re2c 1.0.3

I think I got that version from the Appveyor link pointed to by the Sequencer documentation: https://mdavidsaver.github.io/sequencer-mirror/Installation.html#re2c

On Windows things are not quite as smooth. The old re2c download page on sourceforge contains pre-built binaries for Windows systems, albeit only up to version 0.13.5. If this doesn’t work for you, there is EPICS-re2c, a version of re2c that has been wrapped as an EPICS module. There is also a Windows build of re2c-1.0.3 on Appveyor.

However, that artifact on Appveyor no longer exists, because they appear to only be kept for 1 month.

The re2c source version linked in the documentation that builds with the EPICS build system is here:

https://github.com/FreddieAkeroyd/EPICS-re2c/tree/master

But that is re2c 0.16, so does not seem to be what was used to build 1.0.3.

Where are new EPICS Windows users supposed to find re2c?

Thanks,

Mark
