Hi Guix people,
I have been working on creating a package definition for
pulseaudio-equalizer¹ and when built with the current definition
of the grep package, it prints this error message when running:
grep: Perl matching not supported in a --disable-perl-regexp build
grep: write error: Broken pipe
Searching for that error message, I came across this:
So it seems that, for version 3.8, the pcre input package for grep
should be changed to pcre2. I have made this change in a new
definition which inherits grep and told my pulseaudio-equalizer
package to use that as a propagated input, and that causes the
error to go away. For the sake of completeness, here’s the
definition I used:
(define grep-fixed
(package
(inherit grep)
(inputs (list pcre2))))
Best wishes,
Matt
