[Magic CLI]: `mojo` or `mojo debug` lead to "error while loading shared libraries: libedit.so.2"

Julian-J-S commented 1 month ago

Issue description

When running

mojo or
mojo debug main.mojo

Getting the error: /home/julian/programming/mojo/hello2/.magic/envs/default/bin/mojo-lldb: error while loading shared libraries: libedit.so.2: cannot open shared object file: No such file or directory

However mojo main.mojo works! :green_circle:

Steps to reproduce

Setup project with magic init hello --format mojoproject Run commands from issue description

Version Info

- magic: magic 0.3.1 - (based on pixi 0.29.0)
- mojo: mojo 24.5.0 (e8aacb95)
- OS: Fedora Linux 40 (Workstation Edition)

I am currently having the same issue on Fedora 40. As far as I can see, a workaround for missing libraries on Fedora (including this one) was already discussed here. But it would be nice if these would be covered by the installer instead of leaving them to the user to deal with.

I was trying out mojo following the official docs https://docs.modular.com/mojo/manual/get-started/.

I am on arch, although I feel that the workaround for the same issue I faced will help you on Fedora

$ uname -a                                    
Linux archusb 6.11.9-zen1-1-zen #1 ZEN SMP PREEMPT_DYNAMIC Sun, 17 Nov 2024 16:06:09 +0000 x86_64 GNU/Linux

$ magic init sandbox --format mojoproject # creates a new project
✔ Created /home/teleporterx/Mojo/sandbox/mojoproject.toml
✔ Added max >=24.5.0,<25

$ cd sandbox && magic shell # activates the venv

$ mojo --version
mojo 24.5.0 (e8aacb95)

However, when I try mojo, I get the same error that was mentioned

$ mojo
/home/teleporterx/Mojo/sandbox/.magic/envs/default/bin/mojo-lldb: error while loading shared libraries: libedit.so.2: cannot open shared object file: No such file or directory

and when you check the shared libs

$  ldd .magic/envs/default/bin/mojo-lldb
    linux-vdso.so.1 (0x00007776c266e000)
    liblldb20.0.0git.so => /home/teleporterx/Mojo/sandbox/.magic/envs/default/bin/../lib/liblldb20.0.0git.so (0x00007776b9024000)

libedit.so.2 => not found

I had libedit already installed (but i had the so.0 & others instead of so.2)

$ sudo pacman -Ss libedit
[sudo] password for teleporterx: 
core/libedit 20240517_3.1-1 [installed]
    Command line editor library providing generic line editing, history, and
    tokenization functions

    A small self-contained alternative to readline and libedit that supports

$  ls /usr/lib | grep libedit                            
libeditorconfig.so
libeditorconfig.so.0
libeditorconfig.so.0.12.9
libeditorconfig_static.a
libedit.so
libedit.so.0
libedit.so.0.0.73

Workaround

create a symlink sudo ln -s /usr/lib/libedit.so.0 /usr/lib/libedit.so.2
update an env variable (this is important! If this is not done, executing mojo would throw an unknown error) export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/teleporterx/Mojo/sandbox/.magic/envs/default/lib

** replace with your username & paths wherever appropriate.

and then try mojo

$ mojo # this is with magic shell (activated)

The warning about libstdc++.so.6 is non-fatal—just an issue related to debugging or some internal symbol handling in the library.
