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.
