Hi,
I need to use GNATcoll in my project, the libraries are located under /usr/include/, but I don’t know how to tell gprbuild/gnat or whatever command, to go find the non-standard and non-local libraries under this directory (recursively). I read the user guides but don’t grok anything, it’s too convoluted.
Is there a environment variable like PATH for packages ?
Are you not using Alire?
I tried and failed: "alr search gnatcoll" fails · Issue #1733 · alire-project/alire · GitHub
Does alr search --list work?
Checked your GPR_PROJECT_PATH? I think the dir which contains gnatcoll.gpr has to be in the path.
In my .zshrc I’ve got export GPR_PROJECT_PATH=/opt/gcc-14.1.0-aarch64/share/gpr:$GPR_PROJECT_PATH
No.

Did you find gnatcoll.gpr and make sure that the path is set?
Yes but I see no change (extracts):
> echo $GPR_PROJECT_PATH
/usr/share/gpr
> gnatmake *.adb
diary.adb:16:06: error: file "gnatcoll.ads" not found
gnatmake: "diary-diary_view.adb" compilation error

I don’t think gnatmake will use GPR_PROJECT_PATH. Use gprbuild instead, or try with gnatmake -P yourproject.gpr (which should behave in the same way as gprbuild, but without any advantage, I think).
If you don’t have a GPR file yet, try with this:
with "gnatcoll"
project Diary is
for Source_Dirs use (".");
for Object_Dir use "obj";
end Diary;

Is there a gnatcoll.gpr located in your /usr/share/gpr?
How did you install gcc, gnatcoll-core and gnatcoll-bindings?
yes, that’s how I found the directory in the first place. I installed gcc and gnat through my debian’s official repos. I can try and install things manually too. As for gnatcoll, I downloaded this and ran the corresponding scripts.
