"Neither readline nor libedit was found" on Raspbian 11 (bullseye)

I am trying to compile Ruby and I am getting the following:

root@raspberrypi:~/ruby-3.1.2# make -j4
...
linking ruby
make[2]: Leaving directory '/root/ruby-3.1.2'
make[1]: Leaving directory '/root/ruby-3.1.2'
make[1]: Entering directory '/root/ruby-3.1.2'
*** Following extensions are not compiled:
readline:
    Could not be configured. It will not be installed.
    /root/ruby-3.1.2/ext/readline/extconf.rb:62: Neither readline nor libedit was found
    Check ext/readline/mkmf.log for more details.
*** Fix the problems, then remove these directories and try again if you want.
make[1]: Leaving directory '/root/ruby-3.1.2'
root@raspberrypi:~/ruby-3.1.2#

However I do have both installed:

root@raspberrypi:~/ruby-3.1.2# apt-get install libreadline-dev libedit-dev

libedit-dev is already the newest version (3.1-20191231-2).
libreadline-dev is already the newest version (8.1-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

This works as expected on Raspbian 10, but not sure why it isn't working on Raspbian 11?

root@raspberrypi:~/ruby-3.1.2# lsb_release -a

Also relevant parts of ext/readline/mkmf.log (towards the bottom) shows the following:

The files definitely exist (in the same path as Raspbian 10):

root@raspberrypi:~/ruby-3.1.2# find / | grep readline.h$
/usr/include/readline/readline.h
/usr/include/editline/readline.h

Any ideas?

Solution

  • I deleted and re-downloaded the source code and it compiled as expected! - I am not sure how the source code managed to get corrupt, but that was the solution!
