libpcre2-dev 10.34-7ubuntu0.1 (riscv64 binary) in ubuntu focal

 This is PCRE2, the new implementation of PCRE, a library of functions
 to support regular expressions whose syntax and semantics are as
 close as possible to those of the Perl 5 language. New projects
 should use this library in preference to the older library,
 confusingly called pcre3 in Debian.
 .
 This package contains the development files, including headers,
 static libraries, and documentation.
