Hi Henri,

I saw it. Ive resolved the loading issues of the plugin not loading. I 
no longer see symbol errors.

I have no working media still which is strange. I did notice an error in 
the log which looked suspicious so hopefully I am going down the right 
path here with troubleshooting it...

I notice there are no instances of SLPlugin running when my viewer 
starts, or any instance of dullahan_host, that immediately got me 
suspicious.

This is the error I saw in the log:

2018-03-22T10:08:12Z llplugin/slplugin/slplugin.cpp(194) : error
2018-03-22T10:08:12Z ERROR: llplugin/slplugin/slplugin.cpp(194) : main: 
port number must be numeric


I've looked at the code in slplugin.cpp and see this:
#elif LL_DARWIN || LL_LINUX
         if(argc < 2)
         {
                 LL_ERRS("slplugin") << "usage: " << argv[0] << " 
launcher_port" << LL_ENDL;
         }

         U32 port = 0;
         if(!LLStringUtil::convertToU32(argv[1], port))
         {
                 LL_ERRS("slplugin") << "port number must be numeric" << 
LL_ENDL;
         }

So the argc count is being satisfied... and obviously some parameter is 
being sent that obviously is not numeric and throwing the error.

I ran the viewer under strace and observed some interesting behavior:


4589 execve("/home/alex/ivyviewer/bin/SLPlugin", 
["/home/alex/ivyviewer/bin/SLPlugin", "38655"], [/ 66 vars /]

4592 execve("/home/alex/ivyviewer/bin/SLPlugin", 
["/home/alex/ivyviewer/bin/SLPlugin", "--type=zygote", "--lang=en-US", 
"--log-file=/home/alex/ivyviewer/bin/debug.log", 
"--product-version=(Dullahan:1.1.820 [64bit] - SecondLife/5.1.3.54978 
(Firestorm-private-x64build; firestorm skin)) Chrome/59.0."...], [/ 69 
vars /]

I am seeing SLPlugin called once correctly, with the port number it 
expects, then it is being called a second time with data that it is not 
expecting, thus the error condition is triggered in slplugin.cpp

I know this is a bit of a shot in the dark.... but can you think of any 
possibilities why this could happen?

Just thought I would ask since I am all out of ideas at this point.
