`ruby-build 2.7.1 ...` installs 2.7.0p0 instead

[isikyus]

I originally raised this with asdf (asdf-vm/asdf-ruby#161), which uses ruby-build, but I can reproduce the issue without involving asdf so I'm raising it here instead.

I'm trying to install ruby 2.7.1 on Ubuntu 14.04 (legacy apps :-( ), but the Ruby that gets installed seems to be 2.7.0.

What I did:

$ git clone https://github.com/rbenv/ruby-build.git

ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux]

What I expected:

A Ruby 2.7.1 version string, like ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]

[isikyus]

I've also tried manually unzipping the file https://cache.ruby-lang.org/pub/ruby/2.7/ruby-2.7.1.tar.bz2 and compiling it, which gives me the correct version of Ruby:

$ ruby-2.7.1/ruby --version
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]

I could install this manually as well, but I'd prefer to get it working with a version manager if I can.

[kevinburke1]

I can also reproduce, or, compiling 2.7.1 from scratch installs a bunch of files to "2.7.0" in DESTDIR which seems bizarre.

This is the contents of include/ruby/version.h in the downloaded commit

/* API version */
#define RUBY_API_VERSION_MAJOR 2
#define RUBY_API_VERSION_MINOR 7
#define RUBY_API_VERSION_TEENY 0
#define RUBY_API_VERSION_CODE (RUBY_API_VERSION_MAJOR*10000+RUBY_API_VERSION_MINOR*100+RUBY_API_VERSION_TEENY)

[hsbt]

@kevinburkemeter It's the expected behavior. Ruby API version is different from Ruby version.

@isikyus You might be running into a similar problem I described over here: #1387 (comment)

You're not running (Linux)Homebrew, but Ubuntu 14.04 or something else in your build environment might be doing something similar. ldd /path/to/bin/ruby should show which libruby if any the ruby binary is loading. readelf -d /path/to/bin/ruby and check for the rpath which is built into the binary. If the rpath looks clean it might be LD_LIBRARY_PATH or other things listed in man 8 ld.so.

I've also tried manually unzipping the file and compiling it

If that was on same system it really sounds like ruby-build defaulting to --enable-shared and your by-hand compile not passing --enable-shared to ./configure. I can confirm for you that if you put a 2.7.0 libruby.so.2.7 in the load path of a --enable-shared 2.7.1 ruby binary, ruby --version will print 2.7.0.

You're not running (Linux)Homebrew, but Ubuntu 14.04 or something else in your build environment might be doing something similar. ldd /path/to/bin/ruby should show which libruby if any the ruby binary is loading. readelf -d /path/to/bin/ruby and check for the rpath which is built into the binary. If the rpath looks clean it might be LD_LIBRARY_PATH or other things listed in man 8 ld.so.

This seems very likely; I am in fact running Homebrew on Linux — I'm not sure how I missed mentioning that earlier.

The rpath does seem to be correct:

I can't immediately see any overridden LD variables in my environment, but it's possible they're coming from somewhere else; I'll have to look into this in more detail and get back to you.

ldd does show this Ruby will run with a Homebrew-installed libruby:
