Hi Brian,
there's a problem with the grep package. It uses the internally
provided GNULIB regex library.
Unfortunately, that's the default if the system doesn't provide a more
recent GLibc. Which we'll never do. The problem is this: Native
language support in GNULIB's regex is *only* available, if it's built as
part of GLibc.
I'd like to ask you to rebuild grep 3.9 with the
--without-included-regex option.
That will allow grep to use Cygwin's own regex, which already comes with
basic native language support, and which I'm working on to sbetter
support equivalence class and collation symbol expressions.
Hi Corinna,
We discussed this and I was going to release grep 3.8 test release 3, for
testing with snapshots or when Cygwin 3.5.0 is released, then grep 3.9 came out,
and I realized grep is updated every few months, so that went on the back
burner. I can do a test release for 3.9-2 with that configuration change.
The current release passes all the class tests and works for me and Andrey.
Are there any other implications of language support affecting grep?
Config option --without-included-regex no longer seems to build with grep 3.9 on
Cygwin - may require glibc regex - or may now autoconfig depending on [g]libc?
