Hello, how did you install libvips? If you use brew, libglib-2.0.dylib should be on your system as well.

stereobooster · 2017-09-04T20:53:55Z

brew install glib
Warning: glib 2.52.3 is already installed

Yes it is brew

jcupitt · 2017-09-05T10:22:19Z

I just tried on my mac and it all seems to work for me. Here's what I see. First, brew:

john@katamata ~ $ brew update
Already up-to-date.
john@katamata ~ $ brew install vips

john@katamata ~ $ vips --version
vips-8.5.8-Tue Aug 29 10:02:35 BST 2017

Then Ruby (I'm using the old Apple one):

john@katamata ~ $ which gem
/usr/bin/gem
john@katamata ~ $ which ruby
/usr/bin/ruby
john@katamata ~ $ ruby --version

So I'd check:

you have glib and libvips in /usr/local/lib
you can run command-line vips stuff correctly
your gem and Ruby know about /usr/local

jcupitt · 2017-09-05T10:38:02Z

I tried with the brew Ruby and that worked too.

$ ruby --version

Hello again, it doesn't need to build it, it's all written in Ruby, it uses FFI to call into the dylib.

Were you able to confirm that you have the dylibs in /usr/local/lib and that the command-line vips works?

If they are fine, I think the issue must be with your Ruby install. For some reason it cannot see libraries in /usr/local/lib. You probably need to check your configuration.

stereobooster · 2017-09-07T07:59:52Z

/opt/boxen/homebrew/Cellar/glib/2.52.3/lib/libglib-2.0.0.dylib
vips --version
vips-8.5.8-Mon Sep  4 21:14:48 CEST 2017

your gem and Ruby know about /usr/local

What does this mean?

jcupitt · 2017-09-07T08:54:38Z

Do you have the libraries in /usr/local/lib? I see:

john@katamata ~ $ ls /usr/local/lib/libglib*
/usr/local/lib/libglib-2.0.0.dylib /usr/local/lib/libglib-2.0.dylib
/usr/local/lib/libglib-2.0.a

stereobooster · 2017-09-07T17:11:20Z

Nope, homebrew installed it in other place

brew --prefix glib
/opt/boxen/homebrew/opt/glib

ioquatix · 2018-03-14T23:44:20Z

I'm not sure why this isn't working with Macports but after I manually (yuck) copied the required library to /usr/local/lib, it worked. So, is there something special about /usr/local/lib but not /opt/local/lib?

thubamamba · 2022-07-12T05:31:24Z

Facing this error on M1, any quick fix?

thanadol-git · 2022-08-10T14:00:39Z

Facing this error on M1, any quick fix?

Same for me

jcupitt · 2022-08-10T15:43:01Z

It's an ffi issue -- ruby-vips is asking for glib-2.0.0, and ffi is failing to locate the library.

Here's the ruby-vips code:

https://github.com/libvips/ruby-vips/blob/master/lib/vips.rb#L13-L45

This then runs here in ffi:

https://github.com/ffi/ffi/blob/master/lib/ffi/library.rb#L34-L112

As you can see, it'll first try dlopen("libglib-2.0.0.dylib"), which ought to be the name of the library on your platform. If you don't have your library path set up, dlopen() will fail and you'll drop into ffi's rather haphazard fallback system:

https://github.com/ffi/ffi/blob/master/lib/ffi/library.rb#L129

You can see it has various possible directories wired into the code. If you're lucky, one of these will happen to be correct and it'll work. Homebrew on apple silicon uses a directory that's NOT on that list, so it'll always fail.

I think the best solution is to get your system library lookup working. Try man dyld and have a look at the env vars you can set. I don't have an M1 mac, so I can't experiment myself, unfortunately.

If you look on ffi, you'll find several PRs which attempt to improve this unfortunate situation. ioquatix has tried, and there are others in the list as well:

ffi/ffi#968

ffi/ffi#963

Merovex · 2022-08-15T12:00:46Z

Looking at @jcupitt 's comments, I went to ffi/ffi#968 and to the forked library. From there, I went to gems/ffi-1.15.5/lib/ffi which is the culprit for me.

mv library.rb library.rb.old
create new library.rb and copy contents from https://github.com/eregon/ffi/blob/refactor-library-lookup/lib/ffi/library.rb
create new dynamic_library.rb and copy contents from https://github.com/eregon/ffi/blob/refactor-library-lookup/lib/ffi/dynamic_library.rb

Yields a satisfying:

irb
3.1.2 :001 > require 'vips'
 => true

Yes, this is a hack. But, it looks like there is conversation around a long-term fix, and this gets me through the night.

jcupitt · 2022-08-15T13:40:45Z

Oh nice @Merovex. If you have time, I'd post a patch to that ffi issue as an example of what's fixed it for you. It might help the devs there.
