mu error for libguile-2.0.so.22

[Benjamin Slade]

Updated an arch system, and now mu won't run.

If I try something like

 mu index --rebuild

then I get the error:

mu: error while loading shared libraries: libguile-2.0.so.22: cannot open shared object file: No such file or directory

guile is installed. I tried reinstalling it, and downgrading it, but nothing seems to make a difference.  Can anyone suggest a possible path for resolving/debugging?

Hello Benjamin, 

I run Arch but I am on vacation and on my phone. Yet I feel a bit concerned obviously. A couple of ideas: 

Have you tried removing the libguile .so 22 file, perhaps the entire folder then reinstalling libguile? 

What's the package source for mu4e? Is it coming from AUR ?  If yes which one ? Have you tried fetching mu4e directly from github and compiling it on your system ? 

It's worth noting that if libguile's latest version is problematic then everybody here will soon know...

Best,

Charles.

Hmm, do you have libguile-2.0.so.22 on your system (in /usr/lib or
/usr/local/lib)? Did you run `ldconfig` after installing it?

Kind regards,
Dirk.

Thanks, Charles & Dirk.

So I found that in /usr/lib/ I have a copy of (other) symlinks pointing to `libguile-2.2.so.1.2.0`. So I created a new symlink pointing to this same file from `libguile-2.0.so.22`, and this seems to work.  It may or may not be the true solution, of course, and I'm still not certain why this happened.

I just have the stable `mu` package (0.9.18-1) installed from the Arch repos.
