Description Darrell 2013-04-20 16:30:19 CDT

Attempting to start tderadio from the launcher menu or mini cli results in a sequence of dialogs about being unable to open various plugin modules/libraries.

Starting tderadio from the command line shows the following errors:

The Trinity ltdl loader was unable to dlopen() the shared library '/opt/trinity/lib/tderadio/plugins/libtimecontrol.so' : '/opt/trinity/lib/tderadio/plugins/libtimecontrol.so: undefined symbol: _ZTI18ITimeControlClient'

Adding this bug report to the R14.0.0 etherpad road map.

Comment 1 Timothy Pearson 2013-06-19 10:26:16 CDT

I cannot replicate this.  Are you building against Qt3 or TQt3?

Comment 2 Timothy Pearson 2013-06-19 10:29:17 CDT

Some additional information that might help you find the root cause of your tderadio failure:

_ZTI18ITimeControlClient translates to "typeinfo for ITimeControlClient".  I have pretty much only seen this failure when moc is not properly run on a Qt3/TQt3 header file.  Check your build logs for moc failures (and/or post them here).

Comment 3 Darrell 2013-06-19 12:36:53 CDT

TQt3

Comment 4 Darrell 2013-06-19 18:46:50 CDT

I am not finding any (t)moc related errors in the log.

Comment 5 Darrell 2013-06-19 19:42:24 CDT

I do see the following in the config.log:

Comment 6 Darrell 2013-06-19 20:14:26 CDT

Looks like the problem is --enable-gcc-hidden-visibility. Changing that to --disable-gcc-hidden-visibility and the stderr messages are gone and the app starts.

Comment 7 Timothy Pearson 2013-06-21 18:12:38 CDT

tderadio should then be added to the list of known problem applications with hidden symbols.  Can you update this if it is not already on that list?

Thanks!

Comment 8 Darrell 2013-06-21 18:40:29 CDT

If you mean bug report 1285, tderadio is already on the list as kradio. As I originally created the list, I have no idea why I changed my build script!
