RE: re2c on Windows

["Engbretson, Mark S. via Tech-talk" <tech-talk at aps.anl.gov>]

I use 0.13.5 doing MSVC 2022 builds (and before) on windows 11 and there are no issues using that with base-R7.0.8 and it has no issues building seq-R2-2-9 as of 2 weeks ago.

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
