cygpath not doing anything on a fresh install

cygpath not doing anything on a fresh install

[Antonio Petrelli]

Hello
I just installed cygwin on my Windows 10 laptop.
I need to use the cygpath utility and it simply does not do anything, even
cygpath --help
does anything.

What should I do?

Thanks
Antonio Petrelli

Make sure cygwin1.dll is there. Some "antivirus" may have eaten it.

It's there AFAIK, I see it in the C:\cygwin64\bin directory. Is that right?

Thanks

check that is the last version

ls -l /usr/bin/cygwin1.dll
-rwxr-xr-x 1 matzeri Domain Users 3554998 Jan 31 20:37 /usr/bin/cygwin1.dll

if you updated with a process still running it maybe not the last one

This is what I see:
-rwxr-xr-x 1 MYCOMPANY+Antonio_Petrelli MYCOMPANY+Antonio_Petrelli 3554998
Jan 31 19:37 /usr/bin/cygwin1.dll

So it seems it is OK (notice that I am at UTC+1).

The result is here:

Notice that it caused a Segmentation fault, though.

This looks suspicious:

Process 2480 loaded C:\Program Files\SentinelOne\Sentinel Agent 
21.7.4.1043\InProcessClient64.dll at 00007ffb7c940000

I suspect that SentinelOne is interfering with Cygwin (see 
https://cygwin.com/faq/faq.html#faq.using.bloda).  Can you disable it or at 
least exclude the Cygwin directory from whatever it does?

No I can't, at least not immediately, it's controlled by the corporate.
I think that SentinelOne can be safely put in the list of interfering
software :-(

Thanks anyway

as your corporate is paying for it, you can probably
open a ticket and complain about the behaviour

Maybe they will learn something...
