Hello,

What compiler are you using? Is it a GNAT Community release (https://www.adacore.com/download), or a compiler built from sources at the FSF? (for instance http://gnuada.sourceforge.net/). You can tell running: gprbuild --version.

There is a Makefile file at the root of this repository: I’m not sure what else you would expect. :-)

I think "make" is a command in Cygwin terminal. Updating now the Cygwin64 setup.

Ok. It seems that you have a fairly old toolchain: you’ll probably need to update it in order to be able to build GNATCOLL, anyway. Either download a recent GNAT Community release (https://www.adacore.com/download), either try to get an upgrade from your distribution.

make is indeed a valid command in Cygwin, but what you will find in this repository is Makefile, which is the file that make looks for by default. So all should be fine here.

Thanks for the suggestion.
Downloading recent GNAT Community release.

Ok. By the way, GNAT Community 2018 ships with GNATCOLL, so you will not need to compile it yourself. :-)

Ok.. Good News! Thanks!!
