Description Ben Woods freebsd_committer freebsd_triage 2014-10-08 10:24:17 UTC 
My port of plexhometheater v1.2.2 to FreeBSD is crashing on startup and printing the following error to the terminal:
/usr/local/lib/plexhometheater/system/ImageLib-x86_64-freebsd.so: Undefined symbol "dll_fopen"

The last two lines in the log file show what it was attempting to do at the time:
DEBUG: SECTION:LoadDLL(special://xbmcbin/system/ImageLib-x86_64-freebsd.so)
DEBUG: Loading: /usr/local/lib/plexhometheater/system/ImageLib-x86_64-freebsd.so

This can be fixed by running the following command, after which PHT runs well.
# sed -i.bak s/dll_fopen/fopen/g /usr/local/lib/plexhometheater/system/ImageLib-x86_64-freebsd.so

If I look in the logs after that, I can see there are still some issues:
DEBUG: SECTION:LoadDLL(special://xbmcbin/system/ImageLib-x86_64-freebsd.so)
DEBUG: Loading: /usr/local/lib/plexhometheater/system/ImageLib-x86_64-freebsd.so
ERROR: Unable to load /usr/local/lib/plexhometheater/system/ImageLib-x86_64-freebsd.so, reason: /usr/local/lib/plexhometheater/system/ImageLib-x86_64-freebsd.so: Shared object has no run-time symbol table

Patch to resolve PR194237: fix object files included in libwrapper.a

This patch fixes PR194237 by ensuring libwrapper.a includes the object files with the necessary dll_fopen function.
Patch should be applied with svn patch.

Comment 3 Ben Woods freebsd_committer freebsd_triage 2014-10-08 14:51:43 UTC 
Sorry... not ready to commit just yet. Now instead of ImageLib failing with an error about dll_fopen, I get the following:
$ /usr/local/bin/plexhometheater.sh
/usr/local/lib/plexhometheater/system/ImageLib-x86_64-freebsd.so: Undefined symbol "_ZN11XbmcThreads8pthreads14RecursiveMutex16getRecursiveAttrEv"

Still investigating, will feedback once I have a solution.
