Sailfish OS 4 comes with gcc 8.3, which includes Ada language support. However the version of gcc shipped hasn’t been compiled with the Ada language support.
When compiling an Ada file, gcc says that an Ada compiler isn’t installed.
I’m no compiler expert, but is shipping gcc with Ada support something you folks @Jolla can add in the next version (mainly, if I understood the gcc building docs, just activating ada when building gcc)?
As a workaround for now, compiling an Ada project on an ARM machine, such as Rapsberry Pi (tested on 3B+) with static linking for libraries (important, otherwise it won’t find libgnat), and copying the binary to Sailfish OS works (tested on Gemini)
