Summary: Unresolved symbol due to linkage error
Initial Comment:
While compiling wxruby from source on an Ubuntu system using the
distribution''s own wxgtk 2.8 development package, I noticed a missing
link dependency:
The wxruby2.so module is created at the end of the rake-driven compilation with
the command
g++ -shared -fPIC -o -L. -rdynamic -Wl,-export-dynamic -shared

After installing everything with rake install, trying to use the wx extension
fails with error message
/usr/local/lib/site_ruby/1.8/i486-linux/wxruby2.so:
/usr/local/lib/site_ruby/1.8/i486-linux/wxruby2.so: undefined symbol:
_ZNK11wxMediaCtrl12GetClassInfoEv -
/usr/local/lib/site_ruby/1.8/i486-linux/wxruby2.so (LoadError)
from /usr/local/lib/site_ruby/1.8/wx.rb:12
Searching for the missing symbol, I find it is defined on the system in
/usr/lib/libwx_gtk2u_media-2.8.so.
I try to fix it by adding -lwx_gtk2u_media-2.8 to the linker command line:

After repeating the rake install step, the unresolved symbol error is gone and I
can execute the example programs.
Please fix this error by linking against the library that contains the
wxMediaCtrl class.
