no regular expressions in less

no regular expressions in less

[Basin Ilya]

Hi list.
I've just noticed that regexp search works identically to exact match search in less and it prints this:

    $ /usr/bin/less --version
    less 581.2 (no regular expressions)
    Copyright (C) 1984-2021  Mark Nudelman
    
    less comes with NO WARRANTY, to the extent permitted by law.
    For information about the terms of redistribution,
    see the file named README in the less distribution.

How to solve this?

Are you using 32bit version of cygwin?
In my environment, this only happens in 32bit cygwin.

In 64 bit cygwin, it says:

less 581.2 (PCRE2 regular expressions)

Yes, 32bit.

Hi Basin,

it seems missing for the 32bit version,
on 64bit it is present.

$ less --version
less 581.2 (PCRE2 regular expressions)
Copyright (C) 1984-2021  Mark Nudelman

But for both the library is present

$ cygcheck -cd |grep "pcre.*devel"
libpcre-devel                           8.45-1
libpcre2-devel                          10.37-1

let me investigate why the 32bit has such issue.

Regards
Marco

new 32bit version less-581.2-2
is on the way.
