ok, this is going to sound like a lame excuse :|
Tried to compile juce on my ubuntu setup ... failed - complaining about some alsa headers.
You can config juce (juce_config.h) not to use ALSA. Maybe that'll make it go further...
However looking at the source, it looks like the class is able to share a buffer [insert pattern name here] (i.e. when the class is copied, the reference to the buffer is the same - its not a deep copy) ... you would need to be careful here not to de serialize into a class with refcount that is more than one;
on initial inspection text->text seems to me like where the actual text is stored, so you could possibly use this for serializing, and I would suggest using the operator= function when de-serializing as it seems to encapsulate the functionality of maintaining unique references etc.
Yes, would probably need to. Anyway I did a first attempt at making a wrapper for String that exposes the methods as needed by the deprecated implementation of boost/serialization/string.hpp (in the #if 0 clause), but I got a vector with items instead of a plain string in the output (using the xml oarchive) which is not what I wanted... :(
