libotf.so.1, libotf.so.0, Fedora 39, and Emacs 30.0.50

[Frederick Bartlett]

After testing on another machine, I updated to F39 on my main one.

And Emacs failed with the message "emacs: error while loading shared
libraries: libotf.so.0: cannot open shared object file: No such file or
directory"

This did not happen on my older and slower test machine.

The same library caused trouble about a dozen years ago, but this is a
different problem.

F39 has updated to libotf.so.1.0.0, while Emacs still wants libotf.so.0.

So I added a symlink in /lib64 from libotf.so.0 to libotf.so.1.0.0.

This actually works (for now), but I expect something to break soon ...

Whose problem is this, though? Fedora or Emacs?

Thanks!
Fred

Same seen here. "make bootstrap" did solve.

I wouldn't call it a problem. Something you could expect after OS upgrade.

Best regards, Michael.

Michael,

Thanks for that suggestion. make bootstrap worked like a charm: it even
compiled in under 30 minutes.

If possible use multiple jobs by specifying the -j command line arg to
make.  Then it will build faster.


(Some other) Michael.

If you have a multicore CPU - you can use htop(1) to find out
- and want to prevent compilation from making your computer
nonresponsive by monopolizing the CPU - you can use
taskset(1) on Linux.

It works very well! For example, if you have a quad-core you
can do

  $ taskset -c 0,1 make

to only use cores one and two for the compilation business.
