Thanks for the report, @octonion . I'll look into it.
This is a run-time incompatibility with the GNAT 2021 release, the package GNAT.Case_Utils
has new functions that conflicts with Ada.Characters.Handling
. This was fixed in the gprbuild/libgpr repo: https://github.com/AdaCore/gprbuild/commit/d80333875c76f16623bfc0c3d1c2c6f1987993fe#diff-94a9fa9c99dfbf54eb4a3a0773213e4e321faa2056a89427a5d9a9018a3794fd
Will this problem persist with the new bundled compilers?
No, I checked and libgpr compiles fine with GNAT FSF 10.
I'm hitting the same problem. Would it be possible to release a new version of the crate?
There are no new major releases available for those projects. The only solution so far is to use an older compiler (e.g. GNAT Community 2020).
I've been working fine, but compiled first thing this morning and got it for some reason with the error appearing in gpr.adb
, gnatcoll-projects.adb
and gpr-knowledge.adb
. I haven't changed my environment in any way that I'm aware, I tried using 10.3.1 and it also fails.

It compiles on my side with GNAT 11.2.1
from Alire.

Seems broken with gcc-12
This doesn't look like issue with Alire. I've got same error with gprbuild (fsf gnat from gcc-12) without alire involved.
The following
fails with numerous errors similar to
gpr.adb:1757:13: error: ambiguous expression (cannot resolve "To_Lower")
. Likewise, the dependencygnatcoll_gmp
will exhibit errors while building.This is on Linux Ubuntu 20.04, GNAT 2021 community (but same error with GNAT-9 installed via
apt-get
). I've attached my alire.toml and alire.lock files. toml.zip
