I'm using Windows 10, and I found out, following the message from Joakim, it's really have the gnatcool package on GNAT CE installation on directory \GNAT\2019\share\gpr. The files are:

gnacool.gpr
gnacool_gmp.gpr
gnacool_iconv.gpr

Even if I change unix for x86_64-pc-mingw32 the problem continue.

I imagine it's some PATH, or installation problem. The last line says that could not find gnatcool.gpr file, so I copied it from \GNAT\2019\share\gpr and tried to run again, and I got a lot of errors saying that don't find toolchains, project file, etc.

Actually I'm using Ubuntu Subsystem for Windows 10. It's a command line system. So, to compile Ada programs, I installed gnat using:

sudo apt-get install gnat

And when it doesn't find gprconfig, I installed gprbuild as I mentioned in the first message of this thread.

So, my question is: to run Ada from a command line Linux OS, install gnat from apt-get is the best way? And if yes, how to download and install libraries?
