Most of the Ada packages for Arch Linux have been updated, in particular the latest 2026.2 release of Adacore projects in the Gnatstudio stack.
Unfortunately, the ‘gnatstudio’ package (built from source) crashes on startup with only address backtraces shown, which makes it difficult to discover the reason. The ‘gnatstudio-bin’ package, however, appears to work ok. As a final resort, there is also the ‘gnatstudio-appimage’ package, although it is a few years old now (from the 20240506 release).
Pre-built packages are available at the unofficial Ada repository described here … Unofficial user repositories - ArchWiki .
Please leave a comment on the relevant Arch AUR package page in case of any problems.
