gnat via msys2 pacman + xml/ada

["Björn Lundin" <b.f.lundin@gmail.com>]

Hi!
Is anyone using (recently) the win-64 bit compiler found in msys2 for
windows ?


I found a post here some time ago with instructions, but:

pacman -S mingw-w64-x86_64-gcc-ada
runs fine - installs the compiler

pacman -S mingw-w64-x86_64-gprbuild-gpl
pacman -S mingw-w64-x86_64-aws
pacman -S mingw-w64-x86_64-asis

does not. They do not exist anymore.

I did find another gprbuild
mingw-w64-x86_64-gprbuild-bootstrap-git
which works ok to install.
Looking for xml/ada - I came up short.

so downloading from web I get 4.6.1
Compiling it goes well, but linking - not so much

$ mingw32-make all install
gprbuild -j0 -m -p -XLIBRARY_TYPE=static -XBUILD=Production
-XPROCESSORS=0 xmlada.gpr
gprbuild -j0 -m -p -XLIBRARY_TYPE=relocatable -XBUILD=Production
-XPROCESSORS=0 xmlada.gpr

I even tried to add
  for Switches ("Ada") use ("-L" & "mingw64/bin", "-lgnat");
in share.gpr - but same result - lots of unresolved symbols.


It looks like it cannot find the gnat runtime libs.
Anyone seen this before? And have an idea of how to proceed?
