Installation of MRI 2.0/2.1 fails on Ubuntu 14.04

[ku1ik]

I have upgraded to Ubuntu 14.04 and my MRI 2.1.0 started leaking memory (eating 16gb of ram in 1 minute, swapping etc). Looks like some libs changed and you need to recompile.

Anyway, I removed old 2.1.0 directory and started the installation again. This is the error I'm getting: https://gist.github.com/sickill/9911522

It looks sth is wrong re readline, and it also looks similar to this issue in ruby-build: rbenv/ruby-build#526 (though it applies to Arch Linux there).

Note the same error in both cases:

readline.c:1977:26: error: ‘Function’ undeclared (first use in this function)
     rl_pre_input_hook = (Function *)readline_pre_input_hook;

[ku1ik]

I get the exact same error when trying to install 2.0.0-p451.

Related to ruby 2.x lack of support for libreadline >= 6.3. https://bugs.ruby-lang.org/issues/9630

[ku1ik]

I guess for now one needs to apply a patch with -p.

[plexus]

These should work for now, I took the patches posted in the ruby-build issue

ruby-install -p https://gist.githubusercontent.com/plexus/10021256/raw/9d9edf8d4f03643c7dce4d52c576ad40f2a01760/ruby-2.1.1-readline.patch ruby 2.1
ruby-install -p https://gist.githubusercontent.com/plexus/10021261/raw/305492ebd17308e55eee1baab27568fafaa940cb/ruby-2.0-p451-readline.patch ruby 2.0

[postmodern]

Hopefully they will release patched 2.0 and 2.1 versions soon.

@plexus thx, it works perfectly.

@postmodern I'm having some issues with these installation instructions, where ruby-install passes the -L flags, but the installer doesn't recognize them:

ruby-install -p https://gist.githubusercontent.com/plexus/10021261/raw/305492ebd17308e55eee1baab27568fafaa940cb/ruby-2.0-p451-readline.patch ruby 2.0

==> Caveats
This formula is keg-only, so it was not symlinked into /usr/local.

OS X provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/readline/lib
    CPPFLAGS: -I/usr/local/opt/readline/include

I am seeing some weird quotes in the output of the error, in between the path names:

ld: warning: directory not found for option '-L"/usr/local/opt/openssl/lib'
ld: warning: directory not found for option '-L/usr/local/opt/gdbm"/lib'

@postmodern my problem seemed unrelated to this issue, but was instead related to using 0.4.2, which included abaed04 as a change.

The problem is that the change (somehow, I can't really wrap my head around why this happens) makes the -L arguments end in a newline, as you can see in this output:

-I/usr/local/opt/gdbm/include   -I. -I.ext/include/x86_64-darwin13.1.0 -I./include -I.
    DLDFLAGS = -Wl,-undefined,dynamic_lookup -Wl,-multiply_defined,suppress -L/usr/local/opt/openssl/lib
-L/usr/local/opt/readline/lib
-L/usr/local/opt/libyaml/lib
-L/usr/local/opt/gdbm/lib  -fstack-protector -Wl,-u,_objc_msgSend 

after the first -L argument, and until the second to last, it adds a newline after the argument. When reverting back to 0.4.1, the newlines are gone, and the error messages as well.

New ruby releases are coming soon: http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/62088

@plexus thx, it works perfectly in ArchLinux.
