Cannot run Gnat Studio

I'm trying to run Gnat Studio on Ubuntu 22.04 but I get the following error:

/opt/gnatstudio/bin/gnatstudio_exe: error while loading shared libraries: cannot open shared object file: No such file or directory

I have installed it via the following steps:

  • Downloaded the "x86 GNU Linux (64 bits)" community edition and ran this
  • Ran /opt/GNAT/2021/doinstall
  • Ran /opt/gnatstudio/bin/gnatstudio and got the above error (sudo-running this yields the same error)

I'm wondering if this is down to 22.04 being a very recent release and some shared libraries are missing from the installation bundle?

Any pointers would be much appreciated.



  • It seems you're missing libtinfo5. Just try to install it via

    $ sudo apt install libtinfo5
