I suspect your version of gprbuild is too old and doesn't support GNAT LLVM. Which version of gprbuild are you using? And which version of GNAT/GCC are you using to build GNAT LLVM?

OK, I suspect you will need a more recent version of gprbuild, although I'd recommend first running the displayed gprbuild command with the -v switch, and then run the displayed gprconfig command by hand with -v to get more info about why the toolchain isn't found. The simplest would be to use a more recent version of gprbuild though.

There's already gprbuild -v, so instead try gprbuild -vh to get the call to gprconfig

Same recommendation for your version of GNAT/GCC: 2021 is now getting old, and there is no guarantee that GNAT LLVM will continue being buildable with it.

You'll find more recent versions via Alire.
