Problem executing m4 (127 error, but it is installed)

Problem executing m4 (127 error, but it is installed)

[Kizito Porta Balanyà]

Hello,

I'm trying to build MONIT, but with the new version of cygwin, I need m4.

I have installed it, but when running it, I get a 127 error:

$cd /usr/bin
$ m4
$ echo $?
127

To test that really m4 exists, I try m5:
$m5
-bash: m5: command not found

It is a little strange, Antivirus is configured to no scan the cygwin unit.

I'm usuing, CYGWIN_NT-6.3 MYHOSTNAME 2.0.1(0.287/5/3) 2015-04-30 18:15
x86_64 Cygwin

Do you have any idea ? Can you help me?

Thanks a lot for your time

Probably a missing dll.  What does:

cygcheck m4

state?  I'm guessing you may be missing libsigsegv2, which would show up
as 'cygcheck: track_down: could not find cygsigsegv-2.dll'?  If so,
rerun setup.exe to install it (however, the m4 dependencies should
automatically be pulling it in).

Can you help me?
I just installed openssl-devel and monit's compilation started to fail
(perhaps this information can help)

Thanks a lot.

Bummer, then something else is wrong.

Looks like the executable is fine, then. Maybe it's a virus scanner
interfering, even though you said you've exempted things?  Also, are you
sure you are getting the correct m4?  What does:

$ type m4

say?  What about trying to execute it by absolute path:

$ /bin/m4 --version
$ /cygdrive/c/Windows/KSR/bin/m4 --version

Could it be a collision between a non-executable file named 'm4' vs. the
normal 'm4.exe' that is confusing cygwin .exe magic?  Are you sure that
nothing is messing with PATH and picking up a bogus m4 earlier in the
lookup process?

Sure, cygwin folder is excluded, but Symantec is Symantec.
Due that I can't stop Symantec via services, I rebooted the server and
now m4 works as expected.

Sorry again for the inconvenience. Thanks to your information I
discovered what passed.

Thanks a lot again.
