Hi all,
According to the glib documentation [1] (emphasis mine):
GRegex uses the PCRE library for regular expression matching. The
default is to use the internal version of PCRE that is patched to use
GLib for memory management and Unicode handling. If you prefer to use
the system-supplied PCRE library you can pass the --with-pcre=system
option to, *but it is not recommended*.
[1]: https://developer.gnome.org/glib/stable/glib-building.html
I see that the glib package for ptxdist has a hardcoded
--with-pcre=system option. Is there a reason for this?
Thank you,
Guillermo Rodriguez Garcia

Copying libraries into one's source code and using local versions is a
bad habbit for people who do not have full control over their system :-)

But that's a decision that is taken by the glib developers. I mean,
wouldn't it be wise to use glib as they intend it to be used? They
explicitly mention that the internal version has been patched, and
that using the system-supplied PCRE is not recommended.

So someone probably needs to have a look at what they patched.

The docs say: "the internal version of PCRE that is patched to use
GLib for memory management and Unicode handling"

And most distributions ignore the recommendation because they don't like
bundled libraries. So system-supplied PCRE is actually what most people
use, so I did the same in PTXdist.
