[opensource-dev] Linux x64 - libmedia_plugin_cef.so error
Hi Guys, I am working to try and get a Linux version of the FS viewer running and I have been successful for the most part after fixing a bunch of build issues.. however I seem to have an issue with CEF failing in the new viewer, this can be seen in the logs: 2018-03-20T07:44:13Z WARNING: LLPluginInstance::load: apr_dso_load of /home/alex/fsivy/bin/llplugin/libmedia_plugin_cef.so failed with error 20019 , additional info string: /home/alex/fsivy/bin/llplugin/libmedia_plugin_cef.so: undefined symbol: AtomicOps_Internalx86CPUFeatures Some Googling reveals that AtomicOps_Internalx86CPUFeatures is part of CEF? Has something gone wrong with linking somewhere? What might have gone wrong for this to happen? I am out of ideas as to what it might be. Any thoughts appreciated. -- Kind Regards, Alex. ___ Policies and (un)subscribe information available here: http://wiki.secondlife.com/wiki/OpenSource-Dev Please read the policies before posting to keep unmoderated posting privileges

When typed from a terminal pointing in your viewer directory, what does LD_LIRABRY_PATH="./lib:$LD_LIRABRY_PATH" ldd ./path bin/llplugin/libmedia_plugin_cef.so tells you ? If it can't find libcef.so, then it would explain it... Make sure your viewer_manifest.py script does properly copy all the CEF libraries, binaries and resources in the right places. Also, you will find a working Dullahan Linux plugin on the Cool VL Viewer site (in http://sldev.free.fr/libraries/ ), as well as the corresponding sources (in http://sldev.free.fr/libraries/sources/ ). Note however that this is a modified version with extended parameters for CEF (to learn how to use them, have a look at indra/media_plugins/libvlc/media_plugin_libvlc.cpp in the sources for the Cool VL Viewer v1.26.21.x). This plugin can also be used to compile the viewer with a non C++11 compliant compiler (e.g. with gcc v4.6, even though you will still need to link the viewer to a version of libstdc++.so v6.0.19 or newer (shipped with gcc v4.8 or newer), since this is what libcef.so expects), unlike LL's version.

Interestingly if I run ldd against a pre dullahan era instance of FS: alex@desktop:~/fs_avx2/bin/llplugin$ ldd libmedia_plugin_cef.so linux-vdso.so.1 => (0x7fff637d2000) libllceflib.so => not found librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x7f341b9ed000) libexpat.so.1 => /lib/x86_64-linux-gnu/libexpat.so.1 (0x7f341b7c2000) libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x7f341b43c000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x7f341b0e6000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x7f341aecf000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x7f341aaef000) /lib64/ld-linux-x86-64.so.2 (0x7f341bffd000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x7f341a8d) The 'not found' is probably just due to LD_LIBRARY_PATH not being set. But at least the dependency is there! In my problematic install it seems the dependency is completely missing!

Yes, obviously, libcef.so did not get linked with your plugin...
Check your indra/cmake/CEFPlugin.cmake: the library names changed there,
from libllceflib.a to libdullahan.a. Note also the bit of vodoo magic
needed under Linux to avoid seeing ld "optimizing out" the functions that
are needed in libcef_dll_wrapper.a and libdullahan.a. It should look like
this (note the -Wl,-[no-]whole-archive options):
if (LINUX)
set(CEF_PLUGIN_LIBRARIES
-Wl,-whole-archive
${ARCH_PREBUILT_DIRS_RELEASE}/libcef_dll_wrapper.a
${ARCH_PREBUILT_DIRS_RELEASE}/libdullahan.a
-Wl,-no-whole-archive
${ARCH_PREBUILT_DIRS_RELEASE}/libcef.so
)
endif ()

Ah!! Yes! That will do it... I just checked that cmake file and that
section was wrong (and missing things). I'll try another rebuild with
that. I have a feeling thats going to fix it! Now how can I send you a
nice bottle of wine? :D
Thank you so much! appreciate it!

Apparently a failure to properly link libdullahan.a to your plugin
(the library should be statically linked and so apr_dso_load() should
not search for this method symbol at all)...
Still something wrong in indra/cmake/CEFPlugin.cmake, or perhaps a
failure to specify the $CEF_PLUGIN_LIBRARIES in
indra/media_plugins/cef/CMakeLists.txt
Watch out for (similar) lines in it:
set(media_plugin_cef_LINK_LIBRARIES
${LLPLUGIN_LIBRARIES}
${MEDIA_PLUGIN_BASE_LIBRARIES}
${CEF_PLUGIN_LIBRARIES}
${LLCOMMON_LIBRARIES}
${PLUGIN_API_LIBRARIES}
)

I couldn't spot a problem in either of those files, but my eyes might
have missed something.

Looks fine to me... Putting the blame on a buggy ld, you could try this
trick (specifying libcef.so twice for linking) in CEFPlugin.cmake:
.../...
elseif (LINUX)
set(CEF_PLUGIN_LIBRARIES
${ARCH_PREBUILT_DIRS_RELEASE}/libcef.so
-Wl,-whole-archive
${ARCH_PREBUILT_DIRS_RELEASE}/libcef_dll_wrapper.a
${ARCH_PREBUILT_DIRS_RELEASE}/libdullahan.a
-Wl,-no-whole-archive
${ARCH_PREBUILT_DIRS_RELEASE}/libcef.so
)
endif (WINDOWS)
What is your Linux build system ?

Ah. But in the case of boost and dullahan, it was making use of header only parts of boost right? Relinking libcef twice didnt help sadly.. I gave up for the night and went to sleep hehe.

Yes, only templates from the three boost/function.hpp, boost/bind.hpp and boost/move/unique_ptr.hpp headers are used. > Relinking libcef twice didnt help sadly..

AFAIK, nm only lists exported symbols (i.e. the entries for the definitions), not their invocations from another linked module (the references). nm -C /usr/local/CoolVLViewer-1.26.21/bin/llplugin/media_plugin_cef.so | grep setOnStatusMessageCallback 000ed710 T dullahan_callback_manager::setOnStatusMessageCallback(std::function) 000e4090 T dullahan::setOnStatusMessageCallback(boost::function) These correspond to the two definitions of the homonymous methods in the Dullahan's library classes 'dullahan' and 'dullahan_callback_manager', but nm does not list the call to dullahan::setOnStatusMessageCallback() from media_plugin_cef.cpp, which should correspond to the third string in media_plugin_cef.so.

It lists: U _ZN8dullahan26setOnStatusMessageCallbackESt8functionIFvSsEE So it indeed shows that the libdullahan.a library did not get properly linked to your plugin...

Ah! You're right: nm --print-file-name -C libmedia_plugin_cef.so | grep setOnStatusMessageCallback libmedia_plugin_cef.so:0011ecf0 T dullahan_callback_manager::setOnStatusMessageCallback(std::function) libmedia_plugin_cef.so:00114cd0 T dullahan::setOnStatusMessageCallback(boost::function) libmedia_plugin_cef.so: U dullahan::setOnStatusMessageCallback(std::function) A lot easier to read. Would this suggest that the libdullahan.a library itself I am trying to link against is fine and there is a problem with the viewer build configuration somewhere? -- Kind Regards, Alex. ___ Policies and (un)subscribe information available here: http://wiki.secondlife.com/wiki/OpenSource-Dev Please read the policies before posting to keep unmoderated posting privileges
