I’m trying a text editor called “Kate”. I have a warning in a bottom window:
[12:54:48 PATH Info] /usr/local/gnat12/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:/home/user/bin
[13:04:46 LSP Client Warning] Failed to find server binary: ada_language_server
Please check your PATH for the binary
See also https://github.com/AdaCore/ada_language_server for installation or details
What is the PATH for the ada_language_server binary in FreeBSD?
Add it to your ~/bin? 
EDIT: Also, make sure it’s executable.
Where did you unpack it?
I checked and found the gnat12 and gprbuild packages installed. I looked in the directories and did not see anything that seemed associated with the ada_language_server. I see only the /usr/local/gnat12/bin that seems to have everything. I’m new to FreeBSD and also Ada and don’t know if I had to install ada_language_server or if it is automatically installed. If I have to install it, can you send me a link with the exact package? I know how to set the path.
The ada_language_server is its own program and needs to be installed separately, it does not come with the compiler nor the builder (gprbuild). Also, it seems you installed a fairly old compiler (v12), there are much newer ones. Check this thread with updated information: GitHub - hodong-kim/gcc15-ada: This port is unofficial and maintained separately from the FreeBSD Ports Collection. It is based on modifications to `/usr/ports/lang/gcc15` to enable Ada support. On top of this, I would also recommend you check out Full Ada programming toolchain now on FreeBSD | The FreeBSD Forums Here you can find a compiled version of Alire for FreeBSD, which is the package manager for Ada programs and you should be able to easily install the language server using it.
Best regards,
Fer
Thank you all so far for the replies. Before I posted here, I tried the hodong-kim/gcc15-ada build and it did not go well for me. Alire is also not working. I get a .toml error when I try any command as well. When I tried just the gnatmake or gprbuild commands, all works until the linker step. This gives me an error involving the /ld directory. My version of FreeBSD (GhostBSD) will update on the 16th of this month to FreeBSD 15. I have a spare computer and will try to build a main stream FreeBSD and try that. If that does not work, I’ll try NetBSD. Thanks for the help so far!
