Hi !

I don't have a clue but check the order you put the libraries in, the gcc linker is picky about the order of all libraries, any references to a library must be ahead of the implementing library.

This are just warning messages about the old iostream library, this is deprecated but it's just a warning and should work fine, at least as long as you don't try to mix it with new iostream functions.

Hi, I had the same error... i didn't find answer what is it about and what i did wrong...
but when I write all definitions of my functions in my new class my compile pass :)
so its really simple,but mayby try :)

I don't know if you solved your problem yet, but any such errors coming from object files mean
1. compilation worked :)
2. you forgot to add some lib in the linking flags (the 'lxxx' type of flags). Simply find what lib has those symbols, and add the flag.
For example, for 'libTKBO.so' you should add '-lTKBO' (lose suffix and replace 'lib' prefix with '-l')
Hope this helps,
Vio
