Open pjljvandelaar opened 2 years ago

Hi Atomic-Developers,

I tried to build septum.gpr with alire. septum.gpr uses atomic 0.4.1.

The build however fails with

Looking at https://github.com/Fabien-Chouteau/atomic/blob/14bb7db33dff4b6f1219967a809d0f787cae33cb/src/atomic.ads#L91 I was unable to understand why.

Hope you can solve it soon!

Hi @pjljvandelaar,

Which version of compiler are you using here?

pjljvandelaar commented 2 years ago

Hi @Fabien-Chouteau

I have only installed GNATPRO 23.0.

I am using (according to alr toolchain --select)

Note: gnat is currently not configured. (alr will use the version found in the environment.)
Note: Currently configured: gprbuild=22.0.1

For more info:

> alr toolchain
CRATE        VERSION STATUS    NOTES
gprbuild     22.0.1  Default
gnat_arm_elf 12.2.1  Available
gnat_native  12.1.2  Available
>  alr config
last_build_profile=DEVELOPMENT
toolchain.assistant=false
msys2.install_dir=C:\Users\laarpjljvd\.cache\alire\msys64
toolchain.use.gprbuild=gprbuild=22.0.1

Greetings, Pierre

P.S. If you want more info, just let me know!

Note with gnat_native=12.2.1 compilation succeeds (with some warnings):

So Atomic is not compatible with GNAT Pro 23 yet, you can use GNAT Pro 22 in the meantime.
