C compiler stops on new install under WIndows

[Thomas Beale]

I did a new install of 22.12 on an up-to-date Windows 11 installation and re-compiled existing software. The Eiffel recompile worked (with hundreds of warnings) but the C compilation stopped dead with the following:

Preparing C compilation using already configured mingw C compiler...
Makefile:32: *** missing separator.  Stop.

Not helpful, to say the least.

The compilation goes to completion on my usual machine, same platform, also using mingw.

Unfortunately, I need to get ES going on this machine in order to debug the application with data that can't leave a secure environment.

Any ideas?

No clue, really, but I'd look at environment variables and try running make -n in the affected folder to, maybe, get a little more info.

Maybe show line 32 of Makefile.

I was being a bit lazy, and thinking this might be a well-known error with a well-known explanation (to those in the know).

Here's a screenshot of the Makefile. You'll see that there is a CR LF inserted where there shouldn't be. Manually fixing it isn't much help, since the Makefile is always generated incorrectly. I can't see anything wrong with the paths in the Windows Env vars (2nd screenshot). Editing them shows no extra characters at all at the end of any paths.

So, the proximate problem is clear, but doesn't help much really.

Just curious why the PATH line (32) uses the Eiffel assignment operator instead of the shell one :)

Maybe you have a CRLF in the beginning of the "PowerShell" env variable?

Anders,

amazingly, you are right. Now I wouldn't want you to think I didn't check - of course I went into the PATH variable and hit 'edit' on the paths possibly implicated in that CRLF. Powershell path is included twice (who knows why, I don't care about powershell at all). Following your reply, I thought I had better double check. On one of those two paths I found that if I went to the start of the path, I could move the cursor one char to the right, visually perhaps a single pixel (i.e. invisible). But I could delete one character (not two). Then restarted ES and the compile went to completion.

The machine I am on is a new machine with few things on it - mainly MS corporate-ware.

Thanks for the hint!

I would also like to know why the PATH assignment line uses the ':=' operator, per Roger. It does in the working version of the Makefile as well. Very strange.

Thanks, and great that it helped. I saw the small indentation and thought it was worth a try.
