Bug #13724: make install does not install bundled gems

• Status: Closed

• ruby -v: ruby 2.5.0dev (2017-07-06 trunk 59273) [x86_64-linux]

I believe the usual way to build C (autoconf) software is

autoconf
./configure --prefix=...
make
make install

However, such a sequence does not download nor install bundled gems.
One needs to "make up" before "make install".
This is also not documented in "make help" nor in the README:
https://github.com/ruby/ruby#how-to-compile-and-install

As a consequence many people who build ruby from the source repository might get a ruby without the usual bundled gems (and therefore different from a release).

As an example, did_you_mean does not work without "make up":

$ ruby -e 'p [].eac'

At first sight it seems the standard Homebrew ruby formula does not install bundled gems either due to this:
https://github.com/Homebrew/homebrew-core/blob/a71cdcd43814c8692718eca61bf67ef0b61cdf9e/Formula/ruby.rb#L75-L76

[hsbt (Hiroshi SHIBATA)]

installation of bundled gems requires make update-gems and make extract-gems.

We should add above instructions to README.md.

A few years later this still caught me as a big surprise:
https://github.com/ruby/openssl/pull/319#issuecomment-583781961

Most C software is fully built/installed with ./configure && make && make install, why should Ruby be any different?
