No ada_language_server available on FreeBSD.

No ada_language_server available on FreeBSD.

Do you mean a binary release of ada_language_server?

I suggest to add FreeBSD version of GNAT into Alire. This should help us to make a binary release.

FreeBSD folks, are like gentoo folks. My kernel , all applications are compiled from source.
While i surf the internet , 9 cores are reserved for background compiling, 3 for desktop/surfing.

Please note, i also was unable to compile a postgresql/mysql/sqlite connector for ADA on FreeBSD.
No GUI toolkit for ADA compiled on FreeBSD. I suspect "Linuxism".

Without a GUI , Database connection ADA is very limited to text applications on FreeBSD.

If you would have alire/alr commands i can issue to compile to full toolchain/libraries i'm willing to try and issue error reports / bug messages. Please note i understand FreeBSD is not the First O.S. ADA developers think of.

[reznikmm]

What do you think about migrating to GCC 15 with something like this:

https://github.com/hodong-kim/gcc15-ada

gnat 12 looks too old.

libgpr-26 depends on gnat>=15 while libgpr2-25 depends on gnat>=14. There's probably no point in building an older ada_language_server.

PS GtkAda should be buildable with gnat 12, I guess. At least I've just built it on linux.

GNAT 12, 13, 14 are available. GNAT 15 is going to come soon (as of 10 Mar 2026).

I have built all the dependencies by hand (alire is not always helpful here) and then
I had to apply this patch:

    Recognize FreeBSD as "unix"

Now I have run into the linking problem AdaCore/ada_libfswatch#6

We have libfswatch working on FreeBSD but the final linking stage cannot find other C/C++ libraries needed.

to fix this, export PATH=/usr/local/gnatXX/bin:$PATH with XX is your GNAT version installed. (I am using GNAT 15 but 14 should work, too).

You might need to rebuild gprbuild from /usr/ports/deve/gprbuild for your compiler (the default is GNAT 12).

After this you might need to

 alr toolchain --select
