Problem with Julia API on Ubuntu 24.04 about open_spiel HOT 7 CLOSED

Ohhh, I had totally forgotten about that extra environment variable. Good call, and I just checked: it works! I will add a test that re-enables the Julia API test. Thanks for helping with this!

Note: I tried updating the versions of Julia and CxxWrap in Project.toml but that didn't seem to work.

Note: you should not need to build with python, so you can safely remove -DPython3_EXECUTABLE=python.. I'm just used to always including it.

Got it, I'll look into it soon.

I finally got a workable environment. Still working on it.

Here's what I found with a fresh new docker image of tag ubuntu:24.04:

1. The error with install.sh can be safely ignored. Because at that time, the openspiel lib is not built yet.

Based on discussions here: https://discourse.julialang.org/t/how-to-disable-automatic-precompilation-of-packages-in-julia-1-6/57053

We can set the JULIA_PKG_PRECOMPILE_AUTO environment variable to 0 to stop the precompiling here.

2. The above line needs to be updated:

- cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 $HOME/packages/julias/julia-1.6.1/lib/julia 
+ cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /opt/julias/julia-1.6.1/bin/../lib/julia/libstdc++.so.6

Hmm, I retried and I am still getting that CMake error above that it cannot find the configuration file.

There is also nothing in /opt, because the installer is putting it into $HOME/packages/julias like before.

This is on a fresh install of Ubuntu 24.04.

So I assume you executed like this?

(venv) lanctot@nitro-exp:~/open_spiel/build$ OPEN_SPIEL_BUILD_WITH_JULIA=ON cmake -DPython3_EXECUTABLE=python -DCMAKE_CXX_COMPILER=clang++ ../open_spiel

Well that is not enough since some extra environment variables needs to be set. See

You can simply execute build_and_run_tests.sh to build the lib.

There is also nothing in /opt, because the installer is putting it into $HOME/packages/julias like before.

I see, in that case we don't need that modification.
