Alr symbol lookup error

General
1

Brand new ubuntu installation.

sudo apt install alire
alr --version

It says

alr: symbol lookup error: alr: undefined symbol: __gnat_timeval_to_duration

Alire already installs a whole bunch of gnat libraries so I tried

sudo apt install gnat-13
alr

Comes up with the same error message. ldd on alr shows

Questions:

  1. Which library should timeval_to_duration be defined in?
  2. Is this a bug in the ubuntu (24.10) release?
  3. How do I fix this problem?

Instead of apt, can you try installing Alire through GetAda? That should bring in the latest version; here’s the command, no sudo:

curl --proto '=https' -sSf https://www.getada.dev/init.sh | sh

(You may have to uninstall alire vi apt first)

I don’t recommend using the one in the repository, I could be wrong, but I think it’s a very old version.

Yes, it is a very old version 1.2.1.1b1. I’ll try it when my VM finishes installing

  • libgnat should provide that
  • I’d say so
  • Try with sudo apt install libgnat-*, but I’m not sure if that will make alr to change the used library at runtime.

That’s fixed the problem. How do I mark this as solved.

Unfortunately this didn’t fix the problem.
