Phantomjs: Phantomjs 2.5 expects libwebp.6.dylib, webp 0.6.0 provides libwebp.7.dylib

[Empact]

1. Which version of PhantomJS are you using? Tip: run phantomjs --version.

The 2.5 beta, phantomjs --version outputs:
2.5.0-development

1. What steps will reproduce the problem?

$ phantomjs --version
dyld: Library not loaded: /usr/local/opt/webp/lib/libwebp.6.dylib
  Referenced from: /usr/local/bin/phantomjs
  Reason: image not found
Abort trap: 6

1. Which operating system are you using?

$ brew info webp
webp: stable 0.6.0 (bottled), HEAD
Image format providing lossless and lossy compression for web images
https://developers.google.com/speed/webp/
/usr/local/Cellar/webp/0.6.0 (37 files, 2.0M) *

From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/webp.rb

1. Did you use binary PhantomJS or did you compile it from source?

binary

1. Please provide any additional information below.

linking /usr/local/opt/webp/lib/libwebp.dylib to /usr/local/opt/webp/lib/libwebp.6.dylib seems to work, but I didn't test it against actual webp images.

[vitallium]

Damn. Looks like I need to update the binary.

Here are the contents btw - note I added the libwebp.6.dylib link.

@Empact Can you explain how to do this:

linking /usr/local/opt/webp/lib/libwebp.dylib to /usr/local/opt/webp/lib/libwebp.6.dylib

[Empact]

On linux/unix/mac:
ln -s /usr/local/opt/webp/lib/libweb.dylib /usr/local/opt/webp/lib/libwebp.6.dylib

[santosh-hegde]

@Vitallium When can we get new binary ?

[mattpr]

Looks like webp is a required dependency on macos (at least for me on Yosemite).

The release notification only cites required dependencies for Ubuntu.
https://groups.google.com/forum/#!topic/phantomjs/AefOuwkgBh0

It also appears that system installed QT5 and QtWebKit will be required dependencies as well...but that doesn't seem to be the case with the released 2.5.0-beta macos binary package.
https://github.com/ariya/phantomjs/issues/14458

I know the team is probably overwhelmed with tickets and issues, but just wondering if there is some documentation I missed clarifying the current dependencies and requirements for 2.5.0-beta.

The 2.5.0-beta binary works for me on macos x yosemite (after brew install webp; ln -s /usr/local/opt/webp/lib/libwebp.dylib /usr/local/opt/webp/lib/libwebp.6.dylib). Just starting to wonder if I have an older QtWebkit installed in my system or if it was bundled in the beta binary. Guess I'll try to sort that out later. phantomjs --debug=true doesn't yield any insight into which Qt and QtWebKit are being used as far as I can tell.

Creating the symlink doesn't work on my machine (mac Sierra) - I had to change the command to ln -s /usr/local/opt/webp/lib/libwebp.7.dylib /usr/local/opt/webp/lib/libwebp.6.dylib

[haroon-sheikh]

@Empact Linking doesn't work for me either.
@Vitallium any ETA on updated binary?

[Empact]

@monkpit @haroon-sheikh I installed via homebrew, here's what my package shows (after linking):

[haroon-sheikh]

@Vitallium Do we have an update on this? This is currently blocking a lot of us trying out 2.5.

[ghost]

You can download webp 0.5.2 from google, that generates libwebp.6.dylib. That's how I got round it anyway... I didn't have libwebp.6.dylib on my system at all...

[tute]

This worked for me in Sierra:

cd /usr/local/opt/webp/lib
cp libwebp.{7,6}.dylib

[Empact]

@tute minor point but ln is preferable as it avoids copying the file, just creates an alias for it.

[tute]

Indeed. I must have had a typo cause the ln didn't work for me. Thanks!

[laycoding]

@tute omg thank you very much , ln didn't work for me too, but cp did!

[clarkk]

How did you build and install master when there is no build.py file?

[takuhii]

It's installable via homebrew, so I guess homebrew does all the donkey work... Alternatively I just download it direct from Google

[clarkk]

Are you sure?

Isn't master only available from github?

The latest release is 2.1.1 and I can't use it.. Need some of the fixes comitted after that release

[ghost]

In all honesty I haven't tried it direct from GitHub... Are we talking about the libwebp.6.dylib or PhantomJS in general?

[clarkk]

I just searched all issues and found this with phantomjs 2.5 in the subject..

I'm talking about phantomjs in general.. Can't find out how to build and install master

[takuhii]

Do you use Node? Try my NPM module; phantomjs25-beta

I ported the whole thing across...

[clarkk]

@takuhii no not really but maybe I might if you have a working version available :)

If you have a working instance of phantomjs 2.5 maybe you could make a quick test for me? (This is another issue I just found)

poppler's pdftohtml does seem to strip all spaces
https://bugs.freedesktop.org/show_bug.cgi?id=103724

Could you generate a simple PDF file for me with this content? :)

<div>This is a test</div>

[JoyChou93]

@mattpr brew install webp; ln -s /usr/local/opt/webp/lib/libwebp.dylib /usr/local/opt/webp/lib/libwebp.6.dylib sovled my problem.

[ariya]

Any plan for version > 2.1.1 is effectively abandoned. Please see #15344 for more details.
