When I try to generate unit tests in GNAT 2020 Community Edition (Windows 10 64 bit), I get an error on missing gnattest tool: could not locate gnattest.
Same happens on Ubuntu 20.04 (in WSL) with package gnat-10: could not locate x86_64-linux-gnu-gnattest-10.
Is GNATtest not part of GNAT 2020 Community Edition, as shown on AdaCores website (https://www.adacore.com/gnatpro/comparison)?
Yes in 2020 Community Edition gnattest is not included. Main reason: gnattest is tool based on library ASIS which is no longer maintained. AdaCore is moving towards libadalang library and for now gnattest is a victim of these changes. It will back soon or later to Community Edition (when it will be rewritten to use libadalang). Source: I was hit by this same problem and I got this answer from AdaCore :)
At this moment, you can download source package asis-2019-20190517-18AB5-src.tar.gz from previous version of GNAT and compile it by self. At least for me, it works.
AdaCore are moving away from ASIS to their own libadalang technology, and GNAT CE 2020 doesn’t include ASIS.
The ASIS-based applications in GNAT CE 2019 are
gnat2xml
gnat2xsd
gnatcheck
gnatelim
gnatmetric *
gnatpp *
gnatstub *
gnattest
of which only the ones marked with an asterisk are in GNAT CE 2020 (for macOS, at any rate).
If you do go with @thindil’s answer, it’d be best to install the ASIS tools in their own directory, so as to avoid stomping on gnatpp etc.
For info, gnatelim is missing because - for targets using the GNU linker - -ffunction-sections, -fdata-sections, and -gc-sections do the equivalent job
On Ubuntu you can just install asis applications with : sudo apt install asis-programs
