Plugin Hitting Errors While Loading

[Wazutiman]

I'm trying to create a project that depends on a browser plugin. I'm just getting started, and I wanted to make sure that the plugin would work in CEF, so I was just testing it out in the sample applications. On a windows computer it worked just fine, and I could use the browser plugin without any issues at all, but on an Apple, the plugin is listed as an Installed Plugin when I select the plugin test from the Tests menu (in cefclient) but when the plugin actually tries to load, i get this error:

Code: Select all

2014-04-11 11:45:55.153 cefclient Helper EH[3745:507] Error loading /Library/Internet Plug-Ins/CiscoWebCommunicator.plugin/Contents/MacOS/CiscoWebCommunicator:  dlopen(/Library/Internet Plug-Ins/CiscoWebCommunicator.plugin/Contents/MacOS/CiscoWebCommunicator, 262): can't resolve symbol __DefaultRuneLocale in /usr/lib/libcrypto.dylib because dependent dylib #3 could not be loaded in /usr/lib/libcrypto.dylib

I am wondering what steps to take to try and get this working?

Are you using the 32-bit or 64-bit version of CEF on Mac? Does the plugin work in Chrome on the same system?

I am using the 32 bit version of CEF. And yes, it works in Chrome (and Safari though you didn't ask) on the same system.

Are you using the 32-bit or 64-bit version of CEF on Mac? Does the plugin work in Chrome on the same system?

What does the following command show? Are there any missing dependencies?

Code: Select all

otool -L /Library/Internet\ Plug-Ins/CiscoWebCommunicator.plugin/Contents/MacOS/CiscoWebCommunicator

This is the output from that command.

I am not much of an Apple person, but that to me looks like everything is good. My current train of thought is this:

the line '@loader_path/../Frameworks/libcrypto.0.9.8.dylib (compatibility version 0.9.8, current version 0.9.8)
' to me looks like the plugin is expecting to load the dylib from the Frameworks directory included in the installed plugin, but in the error I got, it showed a that it was trying to load '/usr/lib/libcrypto.dylib'
I am suspicious that the plugin is using the wrong libraries, so my current effort is to see if I can figure out what @loader_path resolves to when the application runs, and/or see if I can make sure the plugin is loading the correct dylibs

In case it is useful, here is the otool output for those two dylibs.

Code: Select all

$ otool -L /Library/Internet\ Plug-Ins/CiscoWebCommunicator.plugin/Contents/Frameworks/libcrypto.0.9.8.dylib

If I make any progress I will update.

Still no resolution. Anyone have a suggestion on what to try next?
