libcef_dll_wrapper.a is missing #27

ghost · 2015-07-31T14:11:12Z

Hi!

hm, in the example for osX the "libcef_dll_wrapper.a" is missing...

greetings ascorbin

Hey guys. I'm considering going down the rabbit hole that is CEF 😝 I'm seeing the same thing here, no libcef_dll_wrapper.a in the addon or in the downloads from cefbuilds.com. Did you build this from source? Hoping to not go through all that, but it may be worth it to get a newer version with 64-bit support anyway..

ofZach · 2015-10-27T15:55:39Z

ha welcome to a dark and mysterious cave! I haven't touched this on windows at all (or looked at it w/ 0.9...) pinging @smallfly will look at this in 0.9 / osx shortly....

mattfelsen · 2015-10-27T16:06:20Z

Believe it or not this isn't for Windows (I've escaped, if only for a little while..) Got a WKWebKit into OF easily but oddly can't get it to respond to mouse events properly, so figured I'd see what was up here ☺️

ofZach · 2015-10-27T16:10:54Z

ha right, when I saw "dll" I tuned out... I'll take a look when I have a moment. here's a .a file I had on my hard drive in the ofxCef addon:

https://www.dropbox.com/s/jz1tf2xilmfl3wd/libcef_dll_wrapper.a?dl=0

can you see if this helps, I have about 8-9 "libcef_dll_wrapper.a" around, I think some are compiled with different settings so I'll try to understand this more clearly when I have a moment.

mattfelsen · 2015-10-27T16:36:48Z

Hm, no dice. With the lib in there I get the same linker errors as if I had removed the lib from the project. Ah well, I may give building a newer version a shot, or keep trying with WebKit, or...

smallfly · 2015-10-27T18:04:38Z

Hi,

I have just reopened this repo yesterday. My plan is to update the add-on (incl. the CEF version - lib and framework - 64 bits on OS X and 32/64bits on Windows), and make the add-on work with OF 0.9.0 (starting with OS X). Hopefully I will have this done by the end of the week, but I can not guarantee it.

To answer your question: yes, you need to compile the libcef lib from the source.

BruceWheaton · 2016-03-07T21:00:03Z

I guess you didn't complete that work? I hit this same error, and 32-bit Mac CEF appears to be deprecated.

BruceWheaton · 2016-03-08T01:46:18Z

Following up... I'm trying to move to modern CEF and OF and OS X and 64-bit. I used the latest CEF, and after much much pain, have got the dll wrapper compiled with lbstdC++ not GNU (which stopped the helper and ofx app compiling with C++11). The key was to edit the deploy target in the CMAKE target, which it calls 'min'.
Haven't made it run yet, I suspect I don't have the libraries in the right place yet. Tried to copy in the CEF framework, but I haven't looked at loader paths. Yuck.
Yes:
dyld: Library not loaded: @executable_path/../Frameworks/Chromium Embedded Framework.framework/Chromium Embedded Framework
Referenced from: /Users/me/openFrameworks/addons/ofxCef/example_ofxCEF/bin/example-ofxCEFDebug.app/Contents/MacOS/example-ofxCEFDebug

The CEF framework I have is the one from the CEF binary download...

ofZach · 2016-03-08T02:08:31Z

sorry I should have followed up - I've done basically the same thing (!) and have 64 bit 0.9.0 osx working, but I did (I think, not 100% sure) roll back some of the changes to what was a more performant version of the addon code. I honestly don't have the bandwidth to do the merge but if you are fine poking around a zip of a working 0.9 / osx thing I'm happy to put it online for you and then take a PR...

BruceWheaton · 2016-03-08T02:48:52Z

Oh, cool. Yes please! I've been digging all day and punting. Love to have a trove that I know will work. Everything else I tried isn't getting me the result I need (Awesomium rendering looks nasty, for instance).

BruceWheaton · 2016-03-08T19:03:37Z

Yes, an example would be great please. I solved the link error - a script that copied in the 32-bit CEF framework, but I only get a blank window with a frame rate counter, so something is off.
Of course, I'm an ofxNewbie.

robotconscience · 2016-03-09T22:48:57Z

Hey @BruceWheaton I'm in the same spot as you. Let me know if you've had any luck!

For other OF 0.9+ w/ CEF-seekers out there, here's what I did so far to at least get stuff compiling:

Download latest CEF

Make Xcode projects based on their instructions:

 $ cd path/to/cef_binary_*
 $ mkdir build && cd build
 $ cmake -G "Xcode"

Open Xcode project and edit these settings for libcef_dll_helper product
- Architectures: Universal
- OS X Deployment target: 10.7
- Other C++ Flags: change "-mmacosx-version-min=10.6" to "-mmacosx-version-min=10.7"
- C Language dialect: C++11
- C++ Standard Library: libc++
Also edited the Scheme to build as "Release"
Build libcef_dll_helper.a and copy files to the addon:
- Chromium Embedded Framework.framework
- libcef_dll_helper.a
- 'include' folder

Beyond that, the only other thing I changed was switching "C++ Standard Library" in cefHelper target to libc++ as well.

robotconscience · 2016-03-09T22:54:12Z

Oh! Update, now it's working!

The issue I was having was cefHelper was throwing errors that it didn't have FMOD (which I ignored). I added a "Run Script" phase to build, and added the default copy-fmod-in script from general OF project (below) and viola, it works.

# Copy libfmod and change install directory for fmod to run
rsync -aved ../../../libs/fmodex/lib/osx/libfmodex.dylib "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/Frameworks/";
install_name_tool -change @executable_path/libfmodex.dylib @executable_path/../Frameworks/libfmodex.dylib "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/MacOS/$PRODUCT_NAME";
# Copy GLUT framework (must remove for AppStore submissions)
rsync -aved ../../../libs/glut/lib/osx/GLUT.framework "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/Frameworks/"

ofZach · 2016-03-09T22:58:24Z

if it's helpful, here's a 0.9 version where I think I have rolled back the addon code for performance reasons (not 100% sure but I found the code got slower in most recent version of the addon). I don't have time to merge this or study this but just zipping it up in case it helps.

https://dl.dropboxusercontent.com/u/92337283/OF/ofxCef_works3.zip

cef is quite hard! happy to have more eyeballs on this on this --

@robotconscience also I think you can remove fmod from the linking on cefHelper, which I may have done here -- that gets rid of the dylib needs, etc

robotconscience · 2016-03-09T23:00:31Z

@ofZach thank you for posting! Totally helpful.

And yes, agreed–CEF is hard an weird, but also pretty cool. Will post if I make any headway! Thanks again for sharing your WIP stuff.

ascorbin · 2016-03-09T23:25:01Z

yey!

BruceWheaton · 2016-03-09T23:37:33Z

Great, thanks. I had mine compiling but it produced no output. Yours came right up - cool.
Just need to see how much javascript and events to fight with! For instance - scrolling events not working on a page? Is that an ofx thing?

ofZach · 2016-03-09T23:42:12Z

hmm - this should be linking scroll up:

https://github.com/ofZach/ofxCef/blob/master/example_ofxCEF/src/ofApp.cpp#L6-L8

there's still alot to connect up...

BruceWheaton · 2016-03-10T01:26:01Z

Ah ha! In your scratch repo, it’s commented out. Thanks! Remind me to look at least a tiny bit before posting next time.
