It literally took me hours to get
gnattestinstalled, from the point of reading the project's README to where I finally had a set of instructions that actually got the binaries on my PATH, so I thought I would save the next person the trouble.The README says to first install libadalang, but libadalang itself recommends to use the Alire crate. Unfortunately, it does not tell us how to do this, which is where many would drop off. If one ventures into the Alire docs and figure out the right incantations, one might end up with
alr build, but it is very unclear where to go from here, asalr installwill not make libadalong available for gprbuild or anything used in libadalong-tools ... Actually, after runningalr -vit does not seem to do anything for libraries? At least nothing is added under ~/.alire.At this point, I figured that there might be a crate for such a common set of tools to avoid all of this trouble, and lo and behold, there was ... not sure why this was missing from the README, though, as it is what most people are after.
