No, not really.
This may ruin you .bat files.

A better solution is to set up a proper .gitattributes file,
like this:

I remember I had a problem once with git doing automatic LF->CRLF on
Windows. The solution was to

git config --global core.autocrlf input

You may or may not want to leave out the --global flag here.

Hi Greg,

I tried it just now and it all built and ran OK with no changes. My dbd file also looks to be with the correct line endings

/mnt/c/devel/wsl-epics-base$ file dbd/softIoc.dbd
dbd/softIoc.dbd: ASCII text

So I think you are right that the issue is line endings. If you run file on the top epics base README what does it give? For me that is also:

/mnt/c/devel/wsl-epics-base$ file README
README: ASCII text

If yours mentions CRLF etc. did you do the checkout using git from WSL or with windows git? Is a git config file getting picked up from somewhere that sets the line endings incorrectly?

I think the dbd files get generated from a .pod file using perl. If the above README is the correct line endings, then I would assume the .pod files are too. Another possibility is then that the wrong perl program is being picked up - Windows strawberry perl would add CRLF. If you type    which perl    in WSL does it look right?

Regards,

Freddie

Subject: EPICS 7 base on WSL2

Anybody tried running EPICS under WSL?  I was just playing around, trying to decide if heading down the EPICS path makes sense for our lab.

I followed the docs at: https://docs.epics-controls.org/projects/how-tos/en/latest/getting-started/installation.html
I had to edit the EpicsHostArch script to change the line endings from CRLF to LF (or was it vice-versa?).  After that, the build went well.  I tried to run softIoc to do a test, and got the following:

$ softIoc
Error: Invalid character 'c'
at or before "c" in file "/home/leblanc/EPICS/epics-base/bin/linux-x86_64/../../dbd/softIoc.dbd" line 1
Error: Invalid character 'a'
Error: Invalid character 'l'
Error: Invalid character 'c'
Error: Invalid character 'o'
Error: Invalid character 'u'
Error: Invalid character 't'
Error: Invalid character 'D'
Error: Invalid character 'O'
Error: Invalid character 'P'
Error: Invalid character 'T'
Error: syntax error
Error: Failed to load DBD file: /home/leblanc/EPICS/epics-base/bin/linux-x86_64/../../dbd/softIoc.dbd

At which point   I decided that was enough for a Friday night.  I wonder if it might also be line endings, since file reports:

$ file EPICS/epics-base/dbd/softIoc.dbd
EPICS/epics-base/dbd/softIoc.dbd: ASCII text, with CRLF, LF line terminators

Am I out to lunch, or is it worth a try next week?
      Greg
