Emacs build fails loading UNICOWS.DLL

[Juan José García-Ripoll]

Hi,

I am trying to build emacs using my own script
(https://github.com/juanjosegarciaripoll/emacs-build) for cloning the
official repo, downloading MSYS2 and building from scratch.

This which worked in the past but with a recent MSYS2 distribution,
Emacs does not seem to build. When it launches 'temacs' it aborts with
an error window that complains about UNICOWS.DLL not being available in
the system (which it is not).

I am puzzled, because I am writing this from a previously installed and
built emacs 27.1.90 and it definitely does not load such library. Am I
missing anything? Any help is appreciated

The build options
/c/Users/juanj/src/emacs-build/git/emacs-27_1_90/configure
--prefix=/c/Users/juanj/src/emacs-build/pkg/emacs-27_1_90-x86_64
--without-native-compilation --with-zlib --with-gnutls --with-xml2
--with-lcms2 --with-json --with-harfbuzz --with-cairo --with-rsvg
--with-png --with-gif --with-tiff --with-jpeg --with-xpm
--disable-build-details --disable-silent-rules --without-dbus
--without-compress-install

Juanjo
