Cool, thanks, glad to see it's not just me.

I'm seeing a bit of a different backtrace than you:

Strange, I don't recall having to move libraries around, maybe I forgot a step.  Did you copy the libraries from /usr/pluto/lib over first?

Ok, i tried it again with a fresh source tree and everything built ok.  I was working with a source tree that I manually built a few parts of (basically manually following the script in the Ubuntu_Helpers folder), so I'm not sure what happened there.

I still can't load the MythTV_plugin.so though (neither the one from the bin dir or the MythTV_Plugin folder), DCERouter quits with the same undefined symbol. 

That seems very strange to me unless you have linked to the lib directory instead of copying it.

Yeah sorry,  I copied the nm and just changed that text to try and avoid confusion, but neither of the files has any symbols.

It was my original intention to look at those mythtv wrappers as well, so I'll try what you did and see what happens here.

Let me know if you can actually get it to run your .so, I'm pretty sure I've got the changes to make it work with the new protocol (not that they're that hard to figure out) I just can't test it

Hmm, I didn't even get this far...

It fails trying to link the orbiter:

Code: [Select]

/home/clehmann/builds/LinuxMCE-1.1-SRC/src/Orbiter/../CreateDevice/UserUtils.cpp:108: undefined reference to `db_wrapper_fetch_row(DB_RES*)'

This symbol looks like it's supposed to come from libplusto_main.so, but when I look at the symbols using nm:

Code: [Select]

clehmann@cascade:~/builds/LinuxMCE-1.1-SRC/src$ nm lib/libpluto_main.so
nm: /usr/pluto/lib/libpluto_main.so: no symbols

So I copy libpluto_main.so that just got built from pluto_main to the lib folder, and everything links just fine.

I'm trying to add support for svn mythtv, so I build the MythTV_Plugin.so by changing to the  MythTV_Plugin and doing a make so. I then copy the MythTV_Plugin.so /usr/pluto/bin and restart the DCERouter, but it won't load due to unresolved symbols:

Code: [Select]

/usr/pluto/bin/DCERouter: symbol lookup error: ./MythTV_PlugIn.so: undefined symbol: _Z20db_wrapper_fetch_rowP6DB_RES

Finally, I copy my new libpluto_main.so to /usr/pluto/lib and try and start the DCERouter again, but it just segfaults.

Code: [Select]

Any ideas?
