Bug description

I'm getting the following error: Failed to start the Kernel. OSError: libedit.so.2: cannot open shared object file: No such file or directory. View Jupyter log for further details.

This occurs when trying to execute mojo code in a .ipynb file inside of vscode. These are the terminal commands I have executed before the opening of vscode:

usr@fedora:~/code/mojo/test$ magic init mojo --format mojoproject
✔ Created /home/usr/code/mojo/test/mojo/mojoproject.toml
✔ Added max >=24.5.0,<25
usr@fedora:~/code/mojo/test$ cd mojo
usr@fedora:~/code/mojo/test/mojo$ magic shell
 . "/tmp/pixi_env_7Qa.sh"
usr@fedora:~/code/mojo/test/mojo$  . "/tmp/pixi_env_7Qa.sh"
(mojo) usr@fedora:~/code/mojo/test/mojo$ mojo --version
mojo 24.5.0 (e8aacb95)
(mojo) usr@fedora:~/code/mojo/test/mojo$ code .
(mojo) usr@fedora:~/code/mojo/test/mojo$ magic --version
magic 0.3.1 - (based on pixi 0.29.0)

after this, in vscode i made a file called learn.ipynb in vscode (I have the mojo extension and jupyter notebook extensions installed) and after selecting the mojo kernel when trying to run any code, the error message appears.

Steps to reproduce

@walter I know lots has changed here in the past month. Is this still an issue?

[Mogball]

This sounds like it could be a dependency issue on Fedora. Maybe magic is missing a dep?

Probably not the Walter you are after. Unsubscribing to thread.

@ematejska , notebooks rely on LLDB, which have a dependency on libedit.so.2 being available on the system. This is similar to https://github.com/modularml/mojo/issues/855 Maybe Zac can figure out how to specify that dependency in the proper way

[teleporterx]

https://github.com/modularml/mojo/issues/3629#issuecomment-2495578802 worked for me to get MOJO-REPL. I just symlinked libedit.so.2 and exported LD_LIBRARY_PATH. But this is just a temporary workaround and would need to be fixed in the future.

[walter-erquinigo]

@teleporterx , do you know where your system has libedit.so.2 by default? We might be able to just add that location to the RPATH of our builds.
